Raumfeld Stereo M

The predecessor to the Stereo M was the “AVF Bild” test winner (1/2013), Video magazine’s “Best Buy Recommendation” (04/07/2012), and won first place in the “Stereoplay” readers’ award (04/2012). Commendations and awards from the German technical press and the positive feedback we’ve received from customers confirm that we created a truly great-sounding Wi-Fi stereo bookshelf speaker. The new Stereo M shares all the same qualities along with innovations that set the bar even higher when it comes to hi-fi streaming in authentic stereo.

Authentic stereo
For audiophile enjoyment with streaming speakers, the same acoustic requirements that apply to traditional wired speakers apply. This means that two identical loudspeakers in a stereo arrangement are an absolute necessity. If each of the two stereo speakers are individually controlled, as is the case with most Wi-Fi loudspeakers from other manufacturers, they will not receive the audio signal at exactly the same time. The resulting imbalance leads to a less than ideal listening experience.

Deep bass
The 3-way system uses a dedicated woofer for the lowest frequencies. This long-throw driver delivers exceptionally rich, deep and responsive bass. A double bass reflex system prevents chuffing and disruptive wind noise.

Precision playback
The midrange driver and tweeter are arranged coaxially, a construction that prevents differences in propagation times and approaches the ideal of a point source. This same technology can also be found in our other Wi-Fi stereo speakers, the Raumfeld Stereo Cubes, with the same result: Instruments and voices are tangibly close and precisely rendered. A waveguide for the tweeter helps create a very broad sound dispersion for an even, well-blended sound that can be appreciated from every listening position.

Replaces much larger stereo systems
The days of amassing a huge amount of equipment, stacking them on shelves and low boards and cabling them together in order to enjoy high-quality music playback are over. The Raumfeld Stereo M performs the tasks of an amplifier, tuner, CD or record player and loudspeakers all in two compact enclosures and without compromise. On the contrary, thanks to a 320 watt integrated, low noise class D amplifier, the Stereo M outperforms many floorstanding stereo speakers.

Preset buttons
4 preset buttons on the Stereo M mean that you are not dependent on the app to control the device. Simply save your favourite music streaming services, Internet radio or your personal music library for direct playback at the push of a button – a nice alternative for early mornings before that first cup of coffee.

Technical highlights
  • An authentic 3-way system (the Speaker M was a 2-way speaker)
  • 320 watts produce high, distortion-free levels
  • A larger enclosure, dedicated long-throw woofer and double reflex vents for deeper, richer bass
  • Easier to control: Preset buttons can be programed for instant access to your favourite tunes
  • More setup possibilities: The Stereo M can be placed on a stand as well

Raumfeld Stereo M review of Frankfurter Allgemeine Zeitung
Raumfeld Stereo M review of Frankfurter Allgemeine Zeitung
"Even the largest speakers delineate spatial dimensions precisely and localize instruments with great care on an imaginary stage, just as we expected."
Frankfurter Allgemeine Zeitung 30.01.2015
"Even the largest speakers delineate spatial dimensions precisely and localize instruments with great care on an imaginary stage, just as we expected. Foundational tones lend the Stereo M pair a rather warm, powerful timbre. The treble shines with a bit more restraint but also with a consistently adequate power. What did surprise was how generously Raumfeld dosed the bass tones – they were much stronger than one would expect from speakers of this size.”

Raumfeld Stereo M review of Audio Test
"For the Stereo M, there is no competition in sight.”
Audio Test 02/2015
“From the very beginning, the compact loudspeakers sound truly large. Rock music has a solid foundation, snare drums and electric guitars have a substantial sound and are powerfully played back. The combination of the 140 mm drivers and bass reflex vent ensures plenty of sound pressure in the midbass and upper bass range.”

“Vocals are very vividly positioned between the stereo M’s so that the playback becomes nearly tangible.“

“The Stereo M’s imaging is at a very high level for a bookshelf speaker. It clearly outplayed a multi-room system we were familiar with in a direct comparison. Its lively playback is especially noticeable with smaller musical groups and modern pop and rock productions. The loudspeakers are easy to set up [...] and commendably fill even larger rooms.

With the Stereo M, Raumfeld has succeeded in making a worthy successor to its midsized streaming loudspeaker. We liked the simple controls, large variety of audio formats and true hi-fi sound. For the Stereo M, there is no competition in sight.”

"Terrific wireless speakers that look and sound impressive"
Trusted Reviews 21.04.2016
"The Stereo M is a pair of wireless bookshelf speakers that fit into Raumfeld’s impressive multiroom audio lineup. [...]
Having listened to numerous small wireless speakers over the years, it was a pleasant change to hear units with true presence. There’s no substitute for size when it comes to speaker cabinets.
The Raumfeld Stereo M are speakers that do bass and wide soundstaging extremely well.[...] These are terrific wireless speakers that look and sound impressive. Few competitors can match their sonic scale, especially at this price."

Raumfeld Stereo M review of Stereoplay
"The Stereo M is strongly recommended for all those who have decided on a multi-room streaming system and enjoy a dynamic, rocking and clean sound in even large rooms.”
Stereoplay 01/2015
"In terms of acoustics, the Stereo M [...] is very ambitious with an authentic 3-way crossover design whereby a 16 cm bass driver is reinforced in the back by a bass reflex vent. The midrange driver and tweeter are nestled together in a coax arrangement. The tweeter is constructed a few centimeters from the cone and has a dispersion angle optimized by a waveguide.”

"The Stereo M exhibits a very brisk pacing from the get-go. Charly Antolinis’ “Knock Out 2000” was pushed into the living room with energy and drive. The compact speakers resounded about the listeners‘ ears with drum hits as well as waves of silky bass with such dynamism and directness so that one would suspect that a full-sized floorstanding speaker at the very least is at work [...].“

“That’s why this is our clear recommendation: The Stereo M is strongly recommended for all those who have decided on a multi-room streaming system and enjoy a dynamic, rocking and clean sound in even large rooms.”

Raumfeld Stereo M review of Hi-Fi Choice
Raumfeld Stereo M review of Hi-Fi Choice
"Respect to Raumfeld. The Stereo M delivers streaming with a hi-fi ethos..."
Hi-Fi Choice 11.06.15

Size matters

"They may look like a throwback from the past, but there's more to these speakers than meets the eye reckons David Vivian"

Sound Quality

"If you wanted, you could put the Stereo Ms on a chunky pair of stands, run the supplied speaker cable connecting the active speaker to its passive sibling neatly along the skirting board, experiment with positioning, place your favourite chair in the sweet spot and, tablet in hand, trial Raumfeld's unusual retro/new-tech fusion as a main system. But, as part of Raumfeld's bigger multi-room streaming remit, that's clearly not their natural home. Positioned too close together on top of a (admittedly pretty solid) chest of drawers is where they have to impress.

My regular Monitor Audio/Edwards Audio second string setup (speakers again less than ideally speaced) sounds lean, fast, airy and very explicit here and, in almost every respect, qualifies as a 'music lover's' hi-fi system. I'm not sure what to expect from the Stereo M, but I could have hardly imagined it would be quite so different. Running through the usual gamut of internet radio stations, Spotify and USB stick-stored CD rips, the sound seems almost ridiculously smooth and velvety in comparison - amply endowed with 'couth' and sophistication, but lacking a degree of energy and sparkle. Not a turn off by any means, just a bit of a shock. Too much of a shock, actually, to entertain any further comparisons with the Monitor Audio/Edwards Audio system. Instead, I am intrigued to see if I can live and get on with a presentation that is so fundamentally skewed from what I am used to.

I suspect that there are two possible reasons why the Stereo M seems to initially sound like this. One, it really is as flat as three year-old lemonade and doesn't like being placed on bedroom furniture. Or two, it is concealing a big Class D stick and, as is sometimes the case, is simply just choosing to speak quietly unless roused to do otherwise.

Going with the second hunch, I turn up the volume and stand back to hear the results. Although the sound remains very 'controlled' and seemingly low in distortion, the gains in presence, weight and dynamic expression seem almost disproportionately potent, boosting the speakers' ability to imbue music with a sense of life and impretus.

The Stereo M can't quite muster the startling immediacy that characterises some true, two-box active designs. That said, the extra weight and resolution of small details are now beginning to lend music a realism that draws me in, the perceived top end roll off being less of an issue. Fed a CD rip of Don Grusin's sumptuaously produced Geography album, for instance, the system sounds satisfyingly solid and propulsive with full-blooded tonal colours and nicely resolved timbres. The bass is a genuine surprise, not just integrating beautifully with the coax mid-treble drivers, but digging deep with real grip and rhythmic integrity..."


"Respect to Raumfeld. The Stereo M delivers streaming with a hi-fi ethos, letting the music make its own case without the addition of artificial sonic sweeteners..."
Raumfeld Stereo M review of i-fidelity.net
Raumfeld Stereo M review of i-fidelity.net
i-fidelity.net 23.02.2015
"The bottom aluminium control panel is a real eye-catcher that endows the otherwise very minimalist enclosure with a hint of extravagance and glamour.”

"The strings have barely begun to strum and one hears and feels the dimensions of the loudspeaker. It plays with ease and confidence and – above all - sublimely.  The playful effortlessness is a pleasure.“

"[...] the Stereo M triumphs as a pair: Relaxed, lively and elegant, [...] without any hint of aggression or overexertion. The soundstage is incredibly differentiated. Raumfeld makes use of the complete stage here with an enormous presence. The active and passive speakers harmonize perfectly; that is to say, in perfect sync. Every musical genre is reproduced with an accurate impulse response, whether rock or classical or jazz. The loudspeakers know how to make clever use of their dynamic and power reserves and don’t overshoot the mark when it should be quieter or more reserved.  Powered by high resolution audio files, the prefect listening experience is produced.”
Raumfeld Stereo M review of HiFi Vision
Raumfeld Stereo M review of HiFi Vision
HiFi Vision 05/2015
“The central feature in the Stereo M is the integrated media streamer that autonomously logs in to one’s home network (Wi-Fi or LAN) after an initial setup and plays back the music made available from PCs or network attached storage devices.“

“One should by all means play high end music files on the Raumfeld Stereo M as the ingenious coax driver system plays them back at a high level. With balanced, clear-as-glass tone and a thrilling 3-dimensionality and precision, the Raumfeld Stereo M expertly reproduces every type of musical genre. The speakers have enough sound pressure and dynamics at their disposal to “rock out” if need be. Thanks to their neutral tuning and realistic 3-dimensionality, fans of jazz and classical music will really get their money’s worth.“

"This is all you need these days: The Raumfeld Stereo M offers a practically complete stereo system with the most modern streaming abilities.“

“High quality music files should be used with the Raumfeld Stereo M, as the clever coax loudspeaker plays at a very high level.”
"With this complete streaming solution, Raumfeld chose to implement a [...]  bass reflex construction with a 3-way system, perfect for powerful, dynamic sound from a manageably-sized bookshelf speaker. An ‘authentic’ long throw bass driver with a 13 cm membrane ensures rich bass tones.“

Test lab and practice
"In the test lab, the Raumfeld Stereo M delivered a truly balanced frequency response with low levels of distortion that kicks in at full levels at about 60 Hertz.”
“High quality music files should be used with the Raumfeld Stereo M, as the clever coax loudspeaker plays at a very high level.”

"The Raumfeld Stereo M looks like an elegant loudspeaker pair with a modern design, but is much more. Behind the chic look, the Stereo M conceals the veritable equivalent of a complete stereo system with modern streaming possibilities. Thanks to its self-sufficient network functionality, internet radio software and integrated streaming services, [...] the fully active Stereo M requires neither an amplifier nor music player or even PC. [...] To top it off, the stereo M set has an excellent sound and sports a look that’s easy on the eyes [...].“

*The score refers to the Raumfeld System. The following devices were tested: The Once S, the Stereo Cubes and the Stereo M

"… the Raumfeld system enjoys great popularity in the multi-room segment, especially for all those for whom nothing less than hi-fi will do.“

"All of the components are well made. The solid metal and wood cabinet conveys a luxurious and premium image.”

"As soon as the multi-room system was set up and supplied with music, the sound of the individual components won us over […] completely. The Raumfeld speakers played with a great sense of openness and had a very fine sound. Above all, the Stereo M fully delivered on hi-fi expectations and gave a spirited performance that had a lot of dynamics at its disposal. This also applied to the smaller loudspeakers in the set which sounded very balanced and offered a lot of power for their size.”

Design, Material & Workmanship

"A really cool feature is the removable protective speaker grilles which adhere to the cabinets magnetically.“

"There’s simply nothing to find fault with in the workmanship or the design.”

Setup & controls

"If the loudspeakers are connected to each other, the setup can begin and is just as easy in this case as with all other Raumfeld speakers.“


"Smiles immediately sprang to our faces when [...] the first strains played from the speakers. The sound is simply insanely good. Colloquially, one would say, "The speakers offer a lot of bang for the buck.”

"The large tweeter, midrange driver and woofer generate a full, well-balanced and truly pure sound. Above all the precision and volume of the sound makes the listening experience a real pleasure. The Stereo M can bring the dynamic and powerful sound of a rock concert to your living room or conjure up relaxing and light jazz. For every occasion and musical taste, these loudspeakers do a good job. I’m hooked!”


"With the Stereo M, Raumfeld brought the first true 3-way bookshelf speaker with a WiFI streaming module to the market and did an outstanding job.“
"I have a clear conscience in giving the Stereo M’s sound the rating “exceptional.””

"If we didn’t know better, tower speakers would have come to mind at first listen. The Raumfeld Stereo M [...] deliver a lot of air pressure.“

"Distorted electric guitars have a great deal of drive and snare drums are reproduced with a powerful foundational tone. The loudspeakers even perfectly master difficult vocals.“

"The coaxial principle employed really pays off here. Instruments are well and clearly distributed in the room, while the midpoint of the stereo plays directly in front of us. Another multi-room system should try to imitate this effect. The hi-fi virtues and modern functionality work in perfect harmony here.”


"Multi-room loudspeakers this size – at the present time, there’s nothing better in the marketplace. Their sound is big, the functionality and the possibilities for expansion are without equal.”

Raumfeld Stereo M review of Area DVD
"When it comes to the sound, we expect great things, and great things are on offer."
Area DVD 15.12.2014
"[Here] the proud owner is offered visual proof that premium sound from all streaming sources can be expected.“

"When it comes to the sound, we expect great things, and great things are on offer."

"The separation of vocals and instrumental parts is masterfully executed at even high levels. [...] [T]he Raumfeld Stereo M manages to never appear aggressive or shrill [...]. In spite of this, the treble range doesn’t sound boring or markedly restrained – on the contrary: It’s lively, fresh and possesses a subtle dynamic with good form.”

"The little Raumfeld Stereo M pair [impressed us] with a solidly constructed soundstage and a fantastic detachment of voice[s]  from the loudspeaker. In the bass range, the Stereo M shows a lot of presence because it lacks neither in enclosure volume nor in driver excursion, and the integrated class D amplifier massively pushes out a total of 320 watts at all times.”

"The sophisticated 3-way construction with coax driver pays off. For each coax driver, a 25 mm tweeter with cloth membrane sits at the center of a 110 mm midrange driver equipped with a coated cellulose cone. The advantage of this ‘point sound source’ is that the sound from the mid and treble ranges originates for the listener from the exact same place, resulting in an exceptional degree of impulse fidelity and excellent group delay. Beneath this, the system still has a few aces up its sleeve thanks to a 140 mm bass driver with a coated polypropylene cone.

"The bass sounds hard and rich; electronic [...] d effects [...] are sent far into the room. High levels don’t lead to any anxieties – on the contrary: The bass range pushes ever further and with all-around enthusiasm into the room.”

"Heavy beat, excellent articulation of the vocal segments, lively, dynamic – in short, first class. The bass pushes assertively and with precision from below, the entirety separates wonderfully from the loudspeakers so that the heart [...] beats faster.”

"With its hi-fi streaming speaker, the Stereo M, Raumfeld presents an additional all-around first class product [...]. Integration into a network is easily accomplished. Solid workmanship and a look typical of the Raumfeld family makes for an attractive Bauhaus-styled loudspeaker. Then, when they let loose acoustically, there’s no stopping them: Powerful, dynamic, with good impulse fidelity and stable levels – they push into sonic realms that many competing bookshelf speakers connected to decent amplifiers are unable to reach. [...] This makes it easy to arrive at a positive assessment: It’s difficult to find anything comparable for the money invested - a bull’s eye for the Berliners."

"The perfect solution for everyone who can do without classic hi-fi towers, but not a full stereo sound.”
HiFi Digital 01/2015
"[...] They have very balanced playback with a powerful yet in no way exaggerated foundational tone, clean mids and clear highs. And their 3-dimensionality is naturally far better than any all-in-one speaker: A clever solution for everyone who would like to forgo hi-fi towers but not a full stereo sound.”


"Solid wooden cabinets and 3-way technology with faultless sound and full 3-dimensionality.”

"Of all the loudspeakers, Raumfeld’s ’Stereo M‘ appealed to us the most  [...]"

Translated from the original German.

"Thanks to their neutral tuning and realistic 3-dimensionality, even classical and jazz music fans will be well served."
HiFi einsnull 06/2014
“For the musically important mid and treble ranges, Raumfeld employs a newly developed coax driver system in which a 25 mm fabric dome tweeter is placed before the 10 cm cone of the midrange driver.  Due to this “on axis” arrangement, phase and group delay errors are completely avoided in the treble and mid ranges [...]"

"Tonally balanced, clear as glass and with a thrilling dimensionality and precision, Raumfeld’s Stereo M reproduces all types of music with panache. They have enough power and dynamics at their disposal to rock out if they need to. Thanks to their neutral tuning and realistic 3-dimensionality, even classical and jazz music fans will be well served.“

"[M]ore than a pair of Raumfeld Stereo M loudspeakers for serious music listening these days is really not required!“

Raumfeld Stereo M review of HiFi Test
“High quality music files should be used with the Raumfeld Stereo M, as the clever coax loudspeaker plays at a very high level.”
HiFi Test 01/2015
„Bei dieser Streaming-Komplett-Lösung setzte Raumfeld auf eine [...]  Bassreflexkonstruktion mit einer 3-Wege-Bestückung, ideal für druckvollen, dynamischen Klang aus einer noch handlichen Regalbox. Für satten Tiefton sorgt ein „echter“ langhubiger Tieftöner mit 13-cm-Membran.“

Labor und Praxis:

„Im Messlabor liefert die Raumfeld Stereo M einen recht ausgewogenen und verzerrungsarmen Frequenzgang, der bereits ab rund 60 Hertz mit vollem Pegel einsetzt.“

„Die Raumfeld Stereo M sieht aus wie ein elegant und modern gestyltes Regallautsprecher-Set, ist jedoch weit mehr. Denn hinter dem schmucken Outfit der Stereo M steckt praktisch eine komplette Stereo-Anlage mit modernsten Streaming-Möglichkeiten. Dank völlig autarker Netzwerk-Funktion, Internetradio-Software und eingebauten Streaming-Diensten [...] benötigt die vollaktive Stereo M weder einen Verstärker noch einen Musik-Player oder gar PC. [...] Dazu klingt das Stereo-M-Set hervorragend und ist auch optisch eine Augenweide [...].“

Help regarding this product
Can I immediately use Raumfeld Speakers and Connectors as UPnP rendering devices?
In order to control a Raumfeld Speaker or Connector via UPnP/AV (e.g. with Windows Media Player) it has to be integrated into a Raumfeld network.

An option to use Raumfeld Speaker and Connector standalone, that means without a connection to the Raumfeld system, is in development.
My devices' wireless signal is permanently low or breaks down frequently
To gain an overview over the signal strength of each Raumfeld devices in your network, open Settings > Network > Network Analysis.

A Loss of WLAN Signal

The constant loss of a device's Wlan signal even at high signal strength is due to interferences with other wireless networks. By changing the Wlan channel, you eliminate this interference and can fix this issue. Should your system contain a Raumfeld Base simply try out different channels as described in the online manual (Modifying of the Channel Setting (Raumfeld Base)) and see if the signal strength becomes steady. Access points from other manufacturers usually offer an according configuration option in their administration interface. 

Alternatively you may contact our service team, which is happy to assist you with the detection of the best channel available.

B Constant Low Signal Strength

If the signal strength of individual wireless devices is constantly beneath 50%, steps should be taken to upgrade the Wlan reception of the device and therewith the music playback reliability. In most cases it is sufficient to reduce the distance or the number of obstacles between your Raumfeld Base and your playback device. Simply check out if the reception increases when positioning the devices at different places.

In general, the less walls and ceilings between the devices, the better the reception is. Thick walls made from concrete or clay brick will especially abate the signal. Often a relocation of a few centimeters is enough to bypass any problems.

Mind the following advice that accounts for both, systems with Raumfeld Base or systems that are run with an access point from another manufacturer:

  • Position the Raumfeld Base or the third party access point you utilise rather high up, on a cupboard for example. Make sure there's some space towards the wall. Do not position the device on the floor or in a corner.
  • If you make use of a wireless phone there may be interferences with the wlan signal. Therefore, do not position the Base or the third party access point you utilise right next to the phone's base station.
  • Set up the devices in a way that ensures there are a minimum amount of obstacles inbetween your access point and the playback device. Avoid setting up the Raumfeld devices in alcoves or behind prominent corners.
  • Make sure there are no large-scale metal bodies between the access point and playback devices (e.g. radiators or fridges)
  • Large plants may also block the signal due to their moisture content and should not be between the access point and playback devices.
 If the reception does not increase after a repositioning we suggest using a standard Wlan repeater or to connect single components of your Raumfeld system with your existing wireless access point (see Connecting of your Raumfeld devices with your personal access point in the online manual). Please contact our service team to find the perfect solution for you.
I’m only able to access the Raumfeld Zones under “available devices“ in my Spotify App. How can I control the individual rooms?
Deactivate the Multiroom Mode for Spotify in the Raumfeld App by switching to the "off“ setting. You will then be able to individually control each device in the Spotify App.
Teufel Streaming (Raumfeld) basics
Would you like to get a comprehensive overview about the possibilities of Teufel Streaming systems? Our Teufel Streaming manual informs you about the basics, operation and integration of music resources. Find out more in the Teufel Streaming handbook: https://manual.teufel.de
I have no more access to the internet radio directory TuneIn in my Teufel Raumfeld app. What could be the reason?
For the further use of the radio service TuneIn, a software update may be required. The update is free of charge and only takes a few minutes. The software can easily be checked and updated:
  1. Start up all devices and opening the Teufel Raumfeld App.
  2. The main menu can now be called up on the app screen by briefly swiping to the right.
  3. First select "Settings" in the main menu, then menu item "System maintenance" and finally "Updates". By simply tapping on the "Check for updates" button, the device will automatically start to search for and download the latest version.
  4. After the download is complete, the update can be re-started by pressing the button again. This takes a maximum of about 3-5 minutes. Afterwards, TuneIn can be used again as usual.
I copied new music to a network share. Why isn't it displayed under My Music?
When you copy new music to a network share you have to manually initiate a rescan in order to see the music on your Controller or in the Raumfeld App, respectively.

In order to do so, go to My Music > Recently Added and tap the button "Update music index" on bottom of the list. Alternatively, visit Settings > Music Resources and activate a scan for new music on the music resource you've copied the music to.

Under Settings > Music Resources there is also an option to make your Raumfeld System check for new music every day. A manual scan is then not necessarily required.
Can different music (Multicast) be played in different rooms?
Multicast (different music in different rooms) is possible with Spotify, but not simultaneously. Due to certain restrictions stipulated by the provider, simultaneous multicast is not possible at the present time.
I use a version 6.0 Android device and am trying to set up my Wi-Fi streaming system. The setup assistant, however, does not continue after the initial screen. How can I proceed?
Make sure that your smart device is signed in to your home WiFi – the same WiFi network you plan to use with your Wi-Fi streaming system. If you are already signed in to your WiFi network, deactivate your smart device’s access to mobile internet for the duration of the setup.
I use an Android device version 6.0 or higher. The music I stream directly from this device drops after a short time. What could be the reason for this?
One reason could be that your smart device is going into standby mode and dropping the connection.

Solution: Add the Teufel Raumfeld app to your standby exception list, also known as your device’s “whitelist.” To do this, go to “Settings” in your Android menu and then “Apps,” “Advanced,” “Battery optimization,” “All apps” and “Raumfeld.”
I can find settings for my subwoofer in the Teufel Raumfeld app. What are these for?
The menu items "subwoofer volume" and "subwoofer crossover frequency" are only stored in the app menu under "room settings" if a Teufel Streaming soundbar is operated over the same Wi-Fi connection. With a soundbar/subwoofer combination, the sound signal is "distributed" to the devices, i.e. the sounbar outputs the higher frequencies and the subwoofer, the lower ones. This signal distribution is defined under the menu item "subwoofer crossover frequency". Installation tips:
  • Leave the crossover frequency on the default setting if you are satisfied with the sound or if the Teufel Streaming subwoofer is located close to the soundbar (recommended).
  • If the subwoofer is placed at the side or at the back of the room, it is possible that the overall sound may no longer be harmonious. In this case, try changing the crossover frequency in the app until you are satisfied with the sound.
  • If, for example, the sound image of the soundbar is too thin, reduce the crossover frequency. If the bass sounds too flat, increase the crossover frequency.
  • You can also adjust the subwoofer volume separately.
Can I use my home cinema with the Teufel Streaming system?
In order to use your home cinema system with your Teufel Streaming system you require a Connector:
  • Connect the analogue or digital output of the Connector to an appropriate input of your home cinema amplifier
  • Connect an analogue output of your amplifier to the analogue input of the Connector
This will allow you:
  • to listen to music from your Teufel Streaming system via your home cinema system
  • to stream the audio signal of TV series or movies into other rooms of your house
Please note that there will be a short delay between video and audio signal when you stream it into other rooms. If you choose to play the audio signal via your home cinema system only, audio playback is of course in perfect sync with the video signal.

Do I need to be experienced with technology (Wi-Fi, SSID, WEP, computers, Internet, programming)?
Knowledge about wireless networks or computer technology is not necessary for setting up or using the Teufel Streaming systems. New devices are added to the system simply at the touch of a button.
I have more than one Raumfeld device and would like to listen to Spotify in the multiroom mode. How does this work?
First check that you have a valid subscription for Spotify Premium. You will also need to have both the Raumfeld and Spotify apps installed on your smart device. Now, open the Raumfeld App and tap on the Spotify symbol under music services or on the home screen. Activate the multiroom mode for Spotify by sliding the switch to the “on” position. Once activated, you can select the rooms where you wish to stream music. These will appear in the Spotify App as Raumfeld Zones.
I want my Raumfeld speakers to use less energy when no stream is playing. Does Raumeld offer an automatic standby mode?
It’s possible to activate a standby mode with all Raumfeld speakers starting with generation 2. To activate this mode, go to the room settings in the app, then select the speaker you would like to configure and “automatically activate standby” from the dropdown menu. Here you will be able to activate “ON” or “Off.” The device’s energy usage in the standby mode will be even lower than the standards mandated by the EU.
Is it possible to reinstall the firmware of a Raumfeld device ("flashing")?
Should one of your Raumeld devices no longer react even after you've disconnected the power and restarted the device, you may reinstall the device's firmware and thereby reset it to factory defaults.

Please note that when reinstalling the firmware all device settings are lost. 

Here you will find advice on reinstalling the firmware of the following devices: 
Reinstalling the firmware in our online manual
Can I connect USB storage to the Raumfeld system?
Music that is stored on USB sticks or USB hard disks will be added to your Raumfeld music collection if the storage device is connected to the host of your Raumfeld system.In a system with a Raumfeld Base the Base is the host. In a system without a Raumfeld Base you may set the host device yourself under Settings > Network > Host Configuration.
USB storage devices that are connected to another Raumfeld device than the host can not be integrated as music resources.Please also note that apart from USB sticks, first-generation Speakers, Ones or Connectors support usb hard disks with their own power supply only. This constraint does not apply to second-generation devices, e.g. Connector 2.

Supported Formats
USB storage devices with the following formats are supported:
  • FAT16 / FAT32
  • NTFS
  • HFS / HFS +
  • EXT2 / EXT 3 / EXT 4
In a few cases problems with USB 1.0 storage has been reported. We therefore suggest to use USB 2.0.
Can I use my iTunes library with Raumfeld?
You may use your iTunes music and playlists in the Raumfeld system. There are several alternatives to do this:

All systems:

Sharing of the iTunes music and playlists on a network share

Your iTunes music and playlists remain on your computer and Raumfeld accesses the files via the network. Please note that they are only available if the computer is turned on.

Alternative methods for systems with a Raumfeld Base:

Copying of iTunes music and playlists onto the Raumfeld Base
Your iTunes music and playlists correspond to the status in iTunes at the time of copying onto the Raumfeld Base. However, you have the option to copy the data again at a later time in order to thereby update it.

Use of the Raumfeld Base as the iTunes Media folder location
Your music library is centrally stored on the Raumfeld Base and iTunes accesses it via the network. Provided that your computer is connected to the home network you will feel no difference to using your iTunes with a locally-stored media library. This method is therefore particularly suitable for desktop computers. Find out more: https://manual.teufel.de/en/online-manual-music-resources.html
Can I listen to the radio on my Raumfeld System?
Yes, via the online service "TuneIn".
Raumfeld offers an equalizer function but I can’t find it in the app. How can I access the equalizer?
The Raumfeld Equalizer has been given a different location within the app. You can now access the sound settings directly via the volume menu.
Does Raumfeld support gapless playback?
Since version 1.2 Raumfeld plays back music gaplessly. That means there is no audible pause between two titles what isn't included into the original recording.
What is special about Teufel Streaming (Raumfeld) compared other multi-room audio products?
Teufel Streaming offers outstanding sound quality. Thanks to roots in the professional audio sector, Teufel Streaming prioritises sound quality above all else. That becomes manifest in the whole audio processing chain - from the usage of high-class audio components to the point of the perfect adjustment of all components to each other.
Teufel Streaming is easy to use, thanks to the development by usability experts and constant consultation with users. Whatever function you want to use you will always reach your goal within a few steps.
Teufel Streaming is complete. Teufel Streaming is a complete multi-room audio system. Third party devices (speaker, data storage, computers) are not necessary in order to use Teufel Streaming.
Which music file formats are supported by Teufel Streaming (Raumfeld)?
Supported audio formats: MP3, WAV, Flac, Ogg Vorbis, ASF, M4A containing AAC or Apple Lossless
Compatible playlist formats: WPL, M3U, PLS, iTunes playlists
Please note that there may be structural bottlenecks in the Wi-Fi transmission of lossless formats. If your music library consists mainly of very large FLAC, Apple Lossless or WAV files, we recommend connecting your Teufel Streaming host device via network cable or using the optional Raumfeld Expand. 

Which speaker is on the left, which one on the right?
In order to allow you to position your speakers perfectly within your room, you can choose which of the two speakers you want to control with the left stereo signal, and which with the right. Find out more: https://manual.teufel.de/en/online-manual-setup-configuring-of-devices.html
How can I add album artwork to my music library?
There are different ways to add album artwork to your music library in order to see them on your Teufel Controller:
  • Embed the artwork within the music file
  • Save the artwork in the album's folder
Also, if your Teufel Streaming system is connected to the Internet, missing artwork will be added automatically (if they can be found on the online music service Last.fm).

Embedding the artwork in the music file

Most media players and special "tagging" applications can be used to embed album artwork in music files.

Saving the cover in the album's folder

If all tracks of an album are stored in their own folder you can simply move the artwork image file to that folder. The Teufel Streaming system will then associate the image file with the album.

Supported image formats, size and resolution

We recommend the usage of JPEG images (300x300 pixels, 72 dpi).

Of course, other image formats (PNG, GIF) and sizes are also supported.
How can I connect a CD or MP3 player?
Raumfeld playback devices come with an analogue audio input (cinch) for connecting your CD or MP3 player, iPhones, iPods etc. The input signal may be played back directly via the connected Raumfeld device, or you may stream the signal to other rooms.

Most MP3 players may additionally be connected to the Raumfeld Base via USB. Should your system not contain a Raumfeld Base you may connect the MP3 player via USB to your Speaker or Connector. 

Please note: As the music library on iPods and iPhones is not directly accessible for third party manufacturers, iPods and iPhones can only be connected via their analogue audio output.
How can I delete imported playlists?
In order to delete imported playlists from the music database you have to delete the corresponding playlist file on the music resource:
  • Use your file management application to navigate to the folder that contains the playlists file (.wpl, .m3u, .pls oder iTunes Music Library.xml). It doesn't matter if it is stored on the Raumfeld Base, USB storage or a network share.
  • Delete the playlist file
If the playlist file was stored on your Raumfeld Base or an attached USB storage your music collection will be updated automatically within a few seconds. Hence, the playlist will no longer be displayed under Playlists > My Music.

If the playlist file was stored on a network share, you have to manually initiate a rescan of the network share in order to see the changes in Playlists > Imported. Find out more: https://manual.teufel.de/en/online-manual-scanning-of-music-resources.html.
How can I import my existing playlists into the Raumfeld system?
The following playlist formats are imported into the Raumfeld system and displayed under Playlists > Imported:
  • iTunes Playlists (iTunes Music Library.xml)
  • Windows Playlists (*.wpl)
  • M3U Playlists (*.m3u)
  • PLS Playlists (*.pls)
In order to import your existing playlists into the Raumfeld system, simply save the corresponding playlist files on a USB storage device, a shared folder or the Raumfeld Base (see also music resources).
How synchronous is the playback of multiple players?
When only Raumfeld devices are grouped in a music zone, they offer perfect synchronisation (less than 5-millisecond phase displacement).  This means that you can use multiple speakers in one room without hearing an echo or hall effect.

Third party UPnP/AV internet radios that are operated with Raumfeld may have less than perfect synchronisation. When positioned in different rooms, however, there is still no echo to be heard.
How do I tag my music collection? Which tagging formats are supported?
To get relevant title information such as the artist or album name of a title, the media server uses the metadata - or tags - of your music files. So in order to browse your music collection by artist, album, or genre, the music files must be tagged accordingly. You can find out more about how to do so at: https://manual.teufel.de/en/faq.html?produkt=1913#faq9
What is the maximum number of rooms that can be filled with sound?
This strongly depends on the Wi-Fi performance. If you have three or more speakers, you should connect the host to your router using an Ethernet cable.
Do I need the same cable length for all speakers?
In our experience, there is no acoustical difference for different cable lengths for lengths up to 15 metres.
The RAMPA insert at the bottom of the speaker sometimes is turned out with the tamping screw. What can I do about that?
Unscrew the tamping screw from the Rampa insert and screw the Rampa insert back into the bottom of the speaker.
I want to save a Chromecast stream on the direct selection keys (not applicable to all devices). How can I do this?
For technical reasons, it is not possible to store Chromecast streams on the direct selection keys.
Ich streame Musik direkt aus dem Chrome-Browser. Die Wiedergabe ist jedoch manchmal verzerrt oder setzt kurz aus. Was kann ich dagegen machen?
The most frequent cause of distortion and drops in playback is insufficiently fast data transfers from the PC to the WiFi speaker. Data transfer rates can be affected by the WiFi router and the internet connection. We recommend enhancing the performance by increasing the WiFi signal strength in the vicinity of your PC and speaker.
The Teufel Raumfeld app setup wizard does not find a device after pressing the setup key on the back of the device. The display shows "Searching for device..." or "No device found". What can I do?
There are many reasons why a Teufel Streaming device may not be found during setup, i.e. when the app displays the notifications "Searching for device“ or "Not found”. The following will cover the most likely causes as well as possible solutions.

1) It’s possible that your home Wi-Fi is unable to recognise the device due to certain settings on your Wi-Fi router.

Solution: You can enable your Wi-Fi to recognise the device by directly connecting the Teufel Streaming device to your router via Ethernet cable and repeating the setup process.

2) Other active network devices may prevent your Wi-Fi router from recognising the device. Solution: Deactivate all devices (such as smart TVs, laptops, smartphones, tablets, AV receivers, media servers) that use your LAN or Wi-Fi network for the duration of the Teufel Streaming setup process. Before beginning a new setup process, be sure to restart your Wi-Fi router and complete the setup using a single smartphone.

3) The use of switches, repeaters and additional access points within your home Wi-Fi network can hinder device recognition. Solution: Either restart all additional network devices or turn off these devices for the duration of the setup process.

4) If you use a cordless phone over a landline (DECT) and have this phone in the vicinity of your router or Teufel Streaming device, it may be disrupting your Wi-Fi signal. This is because both DECT and Wi-Fi use the same 2.4 GHz signal.

Solution: Relocate your DECT base station or switch off your DECT telephone for the duration of the setup process.
The Teufel Raumfeld app indicates an error after selecting the Wi-Fi and entering the network key (Wi-Fi password). What could be the reason for this?
If you're using a smart device with the Android operating system version 5.X (Lollipop), the problem could caused by two possible smart device settings:

1) The setting "Smart network change" switches the smart device to the mobile network whenever the WiFi signal becomes too weak. Since Teufel Streaming requires a continuous Wi-Fi connection, this setting cannot be used.

2) The "Auto IP Support" function determines when the home Wi-Fi network does not support DHCP (the automatic assignation of a network address). Although a very useful feature, Auto IP Support cannot be used with the Teufel Streaming system. This is because Teufel Streaming devices need to be assigned an IP from the router in order to independently communicate with the home network and internet.

Solution: The Android functions "Smart network change" and "Auto IP Support" should be deactivated. Next, ensure that your router allows for DHCP and then repeat the setup process.
Die Teufel Raumfeld App zeigt einen "Hoppla"-Hinweis unmittelbar nach der Raumnamen-Vergabe. Im Display steht "Gerät wird konfiguriert". Woran kann dies liegen?
Other devices in your WiFi network may be preventing the Setup Assistant from completing the setup process.

Solution: Deactivate all devices (such as smart TVs, laptops, smartphones, tablets, AV receivers, media servers) that use your LAN or WiFi network for the duration of the setup process. Before beginning a new setup process, be sure to restart your WiFi router and complete the setup using a single smartphone.

Please note that the processes carried out during the notification "Configuring device..." may take a few minutes to complete. We therefore ask for patience in order to ensure that the setup is indeed experiencing difficulty completing and that your smartphone does not go into standby mode.
Während der Einrichtung muss das WLAN-Passwort eingeben werden, damit Ihre Geräte im Heimnetzwerk angemeldet werden können. Was kann ich machen?
Check that the password you entered is still current. Make sure that you are not using the password for your SIM card, Google account, music service or other account. Teufel Streaming requires the password for your home WiFi. This is sometimes also called the "network key".

Tip I: You'll often find your WiFi password / network key on the back of your WiFi router. As long as this password has not been changed, it should still be valid.

Tip II: The auto correct function in your smart device may be changing the characters you enter. We therefore recommend switching off this auto correct function.
During setup, the Wi-Fi network via which the system is to be integrated in the future must be selected in the app. However, my home network is not listed in the selection list. What could be the reason?
The following are a few reasons why your Wi-Fi network may not appear in the list presented in the app:

1) If the signal strength of your Wi-Fi network is only 30% or less where you are holding your phone, it will not appear. Since the system requires a signal strength greater than 30% in order to function without drops in playback, only networks that offer this minimum signal strength will be displayed.

Solution: Increase the signal strength of your Wi-Fi signal and/or find a better place for your device.

2) It’s technically possible to hide a Wi-Fi network. This option is usually offered in a Wi-Fi router’s settings. If you’ve selected this setting option, your home network will not be displayed within the app.

Solution: Make sure that the Wi-Fi is set to "visible“.
Während der Einrichtung zeigt die App die Meldung "Router inkompatibel" an. Woran kann das liegen?
There can be many reasons for the notification "Wi-Fi router is incompatible”. The most common reasons for this notification have to do with router configurations affecting your home WiFi which can be changed. The following are the most common WiFi settings that may be the cause:

1) The function DHCP (the automatic assignment of a network address) is not switched on. This prevents the Raumefld device from registering with the home WiFi network.

Solution: Activate the DHCP function in your home WiFi router’s settings. Tip: Some manufacturers list DHCP as a feature with names like “Reject unknown devices”. Contact the manufacturer of your router if you are unsure what this feature is called.

2) A so-called Mac filter is switched on in your router. This filter prevents the registration of unknown devices which includes all devices not already using the WiFi network.

Solution: Deactivate the Mac filter for the duration of the setup process or add your device to the router’s list of known devices. Note: Some manufacturers refer to the Mac filter with names like "Only allow known devices.“ Contact the manufacturer of your router if you are unsure what this feature is called.

3) The router is blocking direct communication (the exchange of data) between two or more devices connected to the same WiFi network. Known as “client isolation,” this setting is often preconfigured, especially with guest network access.

It requires direct communication in order to receive information (such as when you press "play“) from your smartphone. The client isolation setting is often overlooked as it does not prevent a device from accessing the internet.

Solution: Do not use a guest WiFi access for your device; deactivate the client isolation feature.

Note: Some manufacturers refer to client isolation under different names. It may also be a preconfigured part of a security level you have chosen for your WiFi network. Contact the manufacturer of your router for more information.
One advantage of streaming with Chromecast is that you can continue to use your usual music app. How can I check if my apps already support Chromecast?
Chromecast built-in already supports 100+ apps, including many popular music services, and works with the Chrome browser. You’ll find an exact overview of all Cast-enabled apps here:


Tip: If you didn’t find your app on this list, you may want to contact the provider directly and ask when Chromecast will be integrated. In the meantime, you should have no trouble finding an alternative from the large selection of Chromecast-enabled apps.
Ich habe eine eigene Sammlung von Musik mit hoher Qualität und möchte diese über eine Chromecast unterstützende Musik-App abspielen. Wieso werden mir die Titel nicht anzeigt?
Chromecast built-in can stream CD-quality audio up to 48 kHz. If your collection has a higher sampling rate, you can stream it via the Teufel Raumfeld App.
I also want to use Chromecast's multi-room function and stream to multiple speakers at the same time. How can I do this?
Multi-room streaming is also possible with Chromecast. To do this, create a grouping of speakers within the free Google Home app which you will need to install on your smart device. You can name created groups on the app.

After you create and name your groups, they will appear alongside individual Cast-enabled speakers in your music app.

Google Home App (Play Store)

App Store iOS
I use the Spotify app to stream to my speakers. I don't see any or not all of my Chromecast speakers under "Available devices". What could be the reason?
In order to stream with Chromecast built-in, you’ll need the most recent version of the Spotify App. We recommend updating your app and trying again. Please note that you will also require a Spotify premium account in order to stream to your speakers.
I like watching YouTube videos. Can I now use Chromecast to wirelessly output the sound of YouTube videos while watching them?
The wireless transmission of audio content from YouTube is possible with the following:

1: A computer running on either the Windows 10/8.1/8/7 32 bit, Mac OS X 10.9 (or higher) or Linux operating systems.

2: A current version of the Chrome browser. You can download the most recent version here:

3: The Chromecast built-in extension for the Chrome browser (if not already integrated)

4: A least one Teufel Streaming device with Chromecast built-in registered to the same Wi-Fi network as the computer using the Chrome browser

Begin a YouTube video. Select the “streaming” option from the “more” menu in the Chrome browser. This will call up a menu displaying all Teufel Streaming devices in the network that can play back the audio.

  • The video displayed on your screen and audio from your speaker may not be in perfect sync.
  • It is not currently possible to directly cast audio from the YouTube app for iOS or Android.

Tip for Android users: You can stream audio from the YouTube app on Android devices using the Android mirroring function. To do so, simply complete the following steps:

Step 1: Install the “Google Home App” and open the menu on the left side.

Step 2: Tap on the option “Screen/Audio streaming” and select the Teufel Streaming device you wish to cast audio to. An active connection will be displayed in your smartphone’s status bar.

Unfortunately, this option is not currently available for smart devices operating on iOS systems.

Step 3: Switch back to the YouTube App and start a video as you normally would. The audio will play from the Teufel Streaming device you just selected.

Please note that the picture and audio may not be in perfect sync.
Ich verfüge über eine sehr große eigene Musiksammlung. Seit ich das Update mit Chromecast built-in durchgeführt habe, reagiert das System öfter nicht. Was kann ich dagegen unternehmen?
The processing of a large number of music files requires Teufel Streaming system resources. This is normal and comparable to a computer that has multiple programs running at the same time. For most music libraries, this does not pose a problem. For exceptionally large libraries, however, such as those in the terabyte range, the system might be strained to a point where normal streaming is compromised.

Solution: Restart all Teufel Streaming devices and deactivate Chromecast built-in.
Der Stream auf meine Teufel Streaming Geräte über Chromecast beginnt erst nach langer Wartezeit oder startet gar nicht. Woran kann das liegen?
There are many possible reasons why your music stream doesn’t start or only begins after a long delay. The following are the most common causes:

1) Chromecast built-in functionality can vary between providers. It’s therefore important to abide by the instructions given by the provider for using this technology. For instance, some request that users first cast and then start an audio stream while others recommend the reverse order of actions. If you are unsure whether you are casting correctly, please ask your app’s service team for assistance.

2) It can take around 20 seconds or even longer in some cases for a stream to be processed. Contact the provider of the music or audio service you use to learn more.
How can I tell if my Teufel Streaming/Raumfeld devices are compatible with Chromecast built-in?
Chromecast is supported by Teufel Streaming / Raumfeld devices which have a Raumfeld logo on the front panel and no external Wi-Fi antenna on the rear panel. Chromecast is also supported by the Raumfeld Soundbar / Sounddeck and the Teufel Sounddeck Streaming / Teufel Soundbar Streaming.
Wie kann ich das Chromecast built-in für aktivieren?
Chromecast built-in can be activated on your Teufel Streaming device once it has updated its firmware to version 1.60 and actualised the Teufel Raumfeld App (iOS/Android). The app will then automatically display the presence of Chromecast-enabled devices present in the network.

Manual activation can also be completed at any time in the Teufel Raumfeld App’s menu under “Music services”.
Can I order the Teufel speakers in different colours than those offered?
To realise the very reasonable sales prices usual for Teufel, it is not possible to offer the speakers in a multitude of housing designs.

This circumstance would drive up the production and storage costs, which would result in a significantly more expensive sales price.

A paint shop in your vicinity will surely be able to repaint the speaker housing to your preferred colour without loss of warranty - after expiry of the eight-week right of return.
How can I install software updates?
All Raumfeld devices regularly connect to the Raumfeld update service to look for updated software versions. If updates are available you can easily install them at the push of a button.

Hence your components keep up to date and you can benefit from advancements in the latest software releases.

Since Raumfeld software version 1.3 it is also possible to install updates via a USB stick. This enables you to apply updates without an internet connection.

Of course we also provide continuous updates of the Raumfeld App for your smartphone. These updates are distributed via your smartphone's app store.
My USB storage is not recognised
Connected to the Raumfeld Base
When USB storage is attached to the Base your Raumfeld system will automatically begin to scan for new music. You can follow the scan progress under Settings > Music Resources. The following are possible causes as to why your USB storage may not be automatically found:

A) The file system of the disk may not be compatible. We support the following formats:

  • FAT16 / FAT32
  • NTFS
  • HFS / HFS+
  • EXT2 / EXT3 / EXT4

B) We seldomly have had reports of issues with USB 1.0 devices. We therefore recommend using devices that support USB 2.0.

Connected to a Raumfeld Speaker or Connector (System without Raumfeld Base)
USB storage that has been connected to a Raumfeld Speaker or Connector can only be used for playback in the Raumfeld system if the device is configured as the Raumfeld Host (see Network in the online manual).

Please also note that for first-generation Speakers and Connectors, apart from USB sticks only USB 2.0 storage with its own power supply or USB sticks are supported. These constraints do not apply to second-generation devices, e.g. Connector 2.
Can I control the Raumfeld System from an iPod Touch or iPhone?
The Raumfeld Controller App turns your iPhone, iPod touch or iPad into a full controller for your Raumfeld multi room audio system. It is available free in the app store.
What is the difference between active and passive speakers?
An active speaker contains the amplifiers for the pair of speakers. You can easily recognise it as it also holds the power connector and the Wi-Fi antenna. The passive speaker is connected to the active speaker via a speaker cable.
Is it possible to combine several pairs of speakers in larger rooms?
If you want to provide a particularly large room with music, you can easily set up several Teufel Streaming speakers in one room. The Room Configuration settings allow you to assign multiple devices to a single room so that you can easily control music selection and volume.
Which Spotify subscription plan do I need in order to stream music (on a single device or in a multiroom setup) from Spotify to my Raumfeld device?
In order to listen to Spotify with your Raumfeld speakers, you need to subscribe to Spotify Premium. Due to certain restricitons stipulated by the provider, the free account is not sufficient to stream with the system. You can learn more about Spotify Premium here
I activated my iPhone/iPad as a resource in Raumfeld. However, it frequently is displayed as being “offline” even though it’s logged in to the Wi-Fi. What causes this to happen?
This can occur when multiple mobile devices are used with Raumfeld at the same time. The iPhone/iPad goes offline after 10 minutes if not in use. This conserves the battery on the iPhone/iPad.

Solution: If the resources are offline, simply open the Teufel Reumfeld app on the device from which you would like to stream digital content.
Welches Netzwerk-Protokoll (SMB) muss ich einstellen, wenn Teufel Streaming auf Musik, gespeichert auf Netzlaufwerken oder in Ordnerfreigaben zugreifen soll?
With network protocol SMB1 Teufel Streaming recognises music files on network drives or folder sharing the best. Set the SMB1 protocol in the properties of your computer or /NAS to listen to music via Teufel Streaming.
The individual titles of my compilations are each displayed as their own album
Compilations or soundtracks are normally composed of various artists. In order to display them as a complete album, the tracks of a compilation must be grouped.

There are many different methods of accomplishing this, assuming that the same album name, or Album Tag, is assigned to all tracks. 
  • Assign the name of the compilation's producer to the tag Album Artist. Use "Various Artists" if the producer's name is unknown.
  • If you use iTunes, you may select for every song that they are Part of a Compilation under Get Info > Info.
  • As long as the album is stored locally on the Raumfeld Base, a network drive or USB storage, it is sufficient to simply save the music files in the same folder. Make sure, however, that only music files pertaining to the compilation are stored within this folder.
In order to edit your music collection's tags, we recommend the following programs:

Media Players
  • iTunes (Windows, Mac OS; only supports MP3, AAC, M4A, Apple Lossless)
  • Windows Media Player (Windows; only supports MP3)
  • Winamp (Windows; supports the same formats as Raumfeld except for WAV)
Special Tag-Editors
  • MP3-Tag (Windows; supports the same formats as Raumfeld except for WAV)
  • MusicBrainz Picard (Windows, Mac OS, Linux; supports the same formats as Raumfeld except for WAV)
