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

Expert reviews

"Even the largest speakers delineate spatial dimensions precisely and localize instruments with great care on an imaginary stage, just as we expected."
FAZ 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 2|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 1|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..."

Conclusion

"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 5/2015
“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.“

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

Conclusion:
"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 [...].“

"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.“

Sound

"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!”

Conclusion

"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.””

Sound

"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.”

Conclusion

"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.”

"The aluminium strip is a true eye-catcher that gives the otherwise very simply deisgned speakers a hint of extravagace and style.”

"[...] the Stereo M makes a strong showing as a pair: Easy-going, lively and elegant, [...] without any aggression or exertion. The soundstage is enormously well differentiated. Raumfeld makes use of the complete soundstage with an enormous presence. Active and passive speakers harmonize perfectly, that is to say, in complete harmony. Every musical genre is implemented with good impulse fidelity, no matter whether the music is rock ‘n’ roll, classical or jazzy, it never overshoots the mark when things are meant to be quieter and more restrained. Fired with high-resolution audio files, an experience of pure listening pleasure ensures.”

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.”

Conclusion
"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."

Raumfeld Stereo M review of HiFi Digital
Raumfeld Stereo M review of HiFi Digital
"The perfect solution for everyone who can do without classic hi-fi towers, but not a full stereo sound.”
HiFi Digital 1|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.”

Conclusion:

"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  [...]"

Raumfeld Stereo M review of HiFi einsnull
Raumfeld Stereo M review of HiFi einsnull
"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.“

Conclusion:
"[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
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 1|2015
"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.”

Conclusion:
"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 [...].“

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.
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 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.
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.
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.
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“.
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:

https://www.google.com/intl/en_us/chromecast/built-in/apps/

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.
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:
https://www.google.com/intl/en/chrome/browser/desktop/

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.

Restrictions:
  • 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.
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.
