With the Stereo M and now the Stereo Cubes, Raumfeld offers bookshelf speakers with a true stereo panorama. You’ll experience dynamic, room-filling sound with a complex soundstage in which individual instruments can be singled out by their sound as well as their relative positions. And thanks to Raumfeld technology, there's no time delay between the two speakers to disrupt the harmonious sound. Expect utter synchronicity and expansive stereo soundstage.

We are one of the few manufacturers to offer this combination of authentic stereo and high- quality synchronous streaming.

Streaming with an added dimension: Authentic stereo

In spite of its ultra compact construction, our engineers in Berlin managed to endow the Stereo Cubes with a hi-fi sound quality comparable to that of large stereo bookshelf speakers. The progressive double bass reflex system integrates 2 bass reflex vents that enable the larger midrange/bass drivers to achieve deep, punchy bass all the way down to 62 Hz – a solid foundation for music at your next party.

The high and midranges are in a coaxial arrangement. A similar design was used with our high-end floor standing stereo speaker, the Definion 5 (Stereoplay Highlight 9/2013). This arrangement minimizes differences in propagation times and approximates a point sound source. The result: Extremely transparent, precise playback over the entire frequency range.

Streaming providers, internet radio, USB, DLNA, UPnP and more

Listen to music via a wide range of streaming providers as well as music from your home network, a USB storage device, or via DLNA or UPnP enabled devices. You can also stream music directly from your Android or iOS device. In addition, Raumfeld guarantees a selection of constantly updated music providers.

Enjoy the same or different music in various rooms

Thanks to its powerful streaming hardware, the Stereo Cubes can function as the centre of a multiroom setup, thus eliminating the need to purchase a Raumfeld Base which is normally required to synchronize music streams in more than two rooms. The Stereo Cubes are, of course, compatible with all Raumfeld devices.

The Stereo Cubes have high-end wooden enclosures for optimal sound quality and an exclusive feel. The combination of lacquer and brushed aluminum gives the speakers a subtly elegant appearance that looks great just about anywhere. The WiFi antenna is integrated into the enclosure. USB port, Ethernet, and a cinch input are all located in the back.

The Stereo Cubes are delivered as a pair.

Techical Details:
  • Progressive double bass reflex system
  • 2-way coax drivers and bi-amping technology
  • A free Raumfeld app allows you to operate internet radio and online streaming services like Spotify Connect
  • Stream from Android, iOS, home network, USB storage device, DLNA and UPnP
Test the Stereo Cubes in your home for up to 8 weeks without obligation.
With Raumfeld, you can listen to millions of songs on Wi-Fi speakers in hi-fi sound quality. High-end audio components and lossless audio transmission deliver a listening experience that is regularly lauded by technical journals for its outstanding transparency, power and depth.

Selecting and controlling playback is effortless thanks to a free app. No additional devices such as amplifiers or AV receivers are required – simply plug the speakers in, connect to the home Wi-Fi and enjoy. All speakers were designed by experienced acousticians in our Berlin headquarters.

"sets new standards in terms of fine resolution"
AudioVideoFoto BILD 1|2015
 [O]ffer [...] authentic stereo sound that sets new standards in terms of fine resolution. The elegant Raumfeld system doesn’t just play a bit in the background, it’s wonderfully suited for concentrated music enjoyment.“

With an overall grade of 2.24, the Raumfeld Cubes achieved third place in a comparison test of 11 Wi-Fi loudspeakers.

Raumfeld Stereo Cubes review of hifitest.de
„[D]ie Cubes [sind] nicht nur "einfach schön" sondern auch einfach zu bedienen. Verbunden mit erstklassigem Sound entsteht so eine echte Alternative für HiFi-Türme.“
hifitest.de 23.07.2014
"Along with all other Raumfeld streaming speakers, the Cube[s] are able to grab just about any music file released on a home network. There are no compatbility issues here.“

"[T]he strength of the Raumfeld system lies in its well thought-out design, the truly advanced multi-room functions (with clients that are served absolutely synchronously) and the intelligent management of network resources for an uncomplicated expansion of the system.”

"[B]oth of the coax drivers playback with precision, and the level stability of these speakers is truly formidable. These two speakers are really a lot of fun, thanks to the app as well as the functionality and sound. For modern people who anyway only listen to digital music files and streams, they present an especially interesting concept.”

Conclusion
"In spite of an ever-increasing range, the Teufel Raumfeld Cubes offer a space-saving solution without compromising on style in any way. And the Cubes are not simply attractive – they are also easy to control. Combined with first-class sound, they amount to a real alternative to hi-fi towers.”

Raumfeld Stereo Cubes review of fairaudio.de
"A very subtle exterior belies the many functions as well as the full-bodied sound of Teufel’s Raumfeld Cube."
fairaudio.de 03.2014
"When it comes to setup, flexibility, graphic interface, in short: "user experience“ – I can attest to the following regarding the Cube as well as the accompanying Raumfeld
App: Everything works well and intuitively, even without special networking knowledge.

In addition: The line-in (stereo cinch on the side of the Cube) as well as the A/D converter can be used to transmit digital signals to other Raumfeld devices. This means that even [...] vinyl can be streamed, it even looks nice on a shelf.

The first impression made by the Cube: Fresh and punchy playback! [...] The Raumfeld Cubes can really rock. The books were vibrating on the shelves! [...] When it comes to the upper frequencies, the Cubes are pleasantly restrained and mature [...] The Raumfeld Cubes have plenty of power and render energetic, powerful playback even at volumes well above normal without distortion or unpleasantly harsh tones.

[Test song: "Fade to Grey“]  The Raumfeld Cube built up the song dynamically and brought out [...]  the tonal nuances. Even the stereo image, with sound sources that ping-ponged back and forth within the panorama, succeeded in being clean and stabile.

[Test song: "Blue Ridge Mountains“] I was again surprised by how clean and refined the stereo image was. [...]

[Test concert: Shostakovich, piano concert no. 2][...] Absolute goose bump inducing objects! I was amazing by how richly and cleanly the Cubes were able to create the illusion of an orchester in the room. [...]  Good fun.

Test Conclusion: Raumfeld Cube
Teufel‘s Raumfeld Cube system is an extremely flexible, practical and still amazingly great-sounding solution for multiroom sound.  A very subtle exterior belies the many functions as well as the full-bodied sound of Teufel’s Raumfeld Cube. Setup and connections are child’s play and the app impresses with its functionality, structure, intuitive features, and good design. The sound is especially impressive thanks to a clean and extensive playback and a successfully balanced tone. […]"

Raumfeld Stereo Cubes review of areaDVD
"The high-performance amplifier and coaxial arrangement of the drivers allow the Cube to deliver a harmonious performance especially in respect to dimensionality"
areaDVD 27.01.2014
"[...] Different music in each room or the same music in all rooms in party-mode - thanks to multiroom technology, both are possible. The Cube is, of course, compatible with other Raumfeld devices. [...]

The Raumfeld Cube’s enclosure is made from MDF with a matte white lacquer finish. The lacquer is evenly and smoothly applied, the corners of the enclosure are slightly rounded. [...] Grilles cover the front, but expose the tweeter, giving the Cube and chic and modern design. The tweeter is naturally also covered by a grille to protect against bumbs, but one made from metal. [...]

The Raumfeld App is used to configure the system and will guide you through the setup of the new Raumfeld speakers in three steps. [...] The Ramfeld App allows you to access your entire music library and play it in various [...] rooms in your home. [...]

Sound
[Test with “Get Lucky” by Daft Punk] The Cubes start out with energy and dynamics and construct a very good stereo image. The impression is especially positive with regards to extensivity and dimensionality. We’ve also discovered that the Raumfeld speakers create a solid foundation and offer a lot of potential in the lower range. The mids are clean with pleasant and distinctive voice reproduction. [...]

The Raumfeld Cubes played the ablum "True North“ by Bad Religion at 24-bit/88.2 kHz. We were again surprised by how well both of these little squares reproduced the drums. Clearly, more structure and volume would be possible; but in spite of this, the Raumfeld speakers bring across a very natural sound and won us over with their excellent dimensionality.

[Test "The Whisper" by Sikk] The track started off with a deep and heavy bass that shouldn’t be played at the maximum level on the compact Raumfeld speakers. Still, they achieve a more than acceptable level with a dry and crisp lower range. The kick also comes across with a rich sound and adds to an authentic total impression. [...]

Conclusion
The Raumeld Cube stereo speakers have a perfect square shape and chic, modern design with solid workmanship. Every the materials – matte lacquer with aluminium elements - lend the speakers an attractive appearance in spite of the not-too-high price of 499 EUR. The high-performance amplifier and coaxial arrangement of the drivers allow the Cube to deliver a harmonious performance especially in respect to dimensionality and an even tone quality at any volume. [...] While with many manufacturers, it would be better to have a degree in network administration, configuration and setup with the help oft he Raumfeld App was a breeze."

Easy Music Streaming

"500 Euros gets you active loudspeakers with integrated WLAN reception, a USB port, and an analogue audio input. One loudspeaker contains the connections and electronics, the second box is connected to the first with a stereo cable. The loudspeaker has a volume rocker switch. All other functions are controlled via a smartphone app available for Apple and Android phones or the Raumfeld Controller. The download is easily accomplished [...]

The player in the app can work [...] with many file types. A mobile phone, an external hard drive via USB port, shared folders on PCs, network players (NAS) as well as DLNA servers. [...] In addition, the software includes the Internet radio provider TuneIn that offers many stations, a good search function, and podcast support. Music subscription options like Last.fm, Napster, MTV Music and simfy are also included [...]

The coaxial bass reflex construction impresses in spite of its small size: The 13 centimeter drivers deliver powerful playback down to 60 Hertz and reproduce voices and music with a full-fledged sound. In front of this is a dome tweeter protected by a metal grille. Thanks to point source sound dispersion, the sound image is well integrated even at a distance. The sonic die  render a timbre that is warm and balanced with a slight emphasis on the mid tones. [...]

Conclusion:
"These [...] little cubes will win you over with their pleasant sound, easy setup, and many connection possibilities. The 500 Euro price is justified in the context of the well-executed total package.”

“We were surprised quite how wonderful these speakers sounded"
TechFruit 16.09.2015
Sound

“[...] here is where Raumfeld really shines. The sound is clear and warm across the frequency range, comparing favourably with a mid-range separates setup. The bass is tight and snappy, making sure you can pick out every note in even the most intricate basslines, the middle is lively, and the top end stays clean and crisp.”

Conclusion
 
“We were surprised quite how wonderful these speakers sounded, and at their price you would be very hard pushed to find an amp and speaker separates setup that could match them. The fact that they also offer WiFi streaming and connect to all the most popular music streaming services means that if you are in the market for a new audio setup on a budget then the Stereo Cubes should be near the top of your list.”

"[T]he stereo set really rocks at full volume!”
hw-journal.de/ 02.07.2015
A detailed look

"Just as with the Raumfeld One S, the quality of the workmanship proves itself to be truly beyond reproach.”

"The quality of the materials used in the Cubes, [...], is really top notch. The high-quality MDF wood of the cabinet conveys a very pleasant feel.
The polished aluminium accents on the front give the loudspeakers a certain something that underscores their exclusive status.“

Test / soundcheck

"If there’s one thing the Raumfeld Stereo Cubes aren’t it’s the sort of effect enhancer one can hear at any electronics market. Both cubes go about their business cleanly and in sync […]“

"[...] the Cubes deliver a very neutral sound that is little effected by flamboyantly presented low tones.”

"Short and to the point, the stereo set really rocks at full volume!”

Conclusion

"No razzle-dazzle, no distortion, the Raumfeld Stereo Cubes prove themselves to be sonically neutral and ‘honest‘ loudspeakers."

"Added to this is the doubtless high-quality workmanship and choice of materials fort he cabinet as well as their overall lokk and feel and coloring.“

"All-in-all, the Raumfeld Cubes, after the little One S, represent the logical extension of a listening zone as well as the next step in terms of expanding the system from the line up of the German streaming manufacturer.“

"From our side, we give the Raumfeld Stereo Cubes a clear purchase recommendation.”

Design & workmanship

"The product name couldn’t be more appropriate: The Raumfeld Stereo Cubes look like loudspeakers in cube form and measuring 19.5 x 19.5 x 19.5, they display the appropriate dimensions.“

"We like the Raumfeld Stereo Cube’s minimalist and attractive design that makes a very attractive impression thanks to the metal accents [...]“

Characteristics & sound quality

"In terms of the system’s controls, we weren’t [...] able to find any ground for criticism.”

"[...] we weren’t disappointed! The bass playback is first class: The 130 mm midbass drivers reach down deep and produce bass that is punchy and precise without neglecting the midrange. The result is a warm and very pleasant soundstage rounded off by the 28 mm tweeters. These are responsible for the consistently pleasant highs whereby even the fine details can be discerned.”
 
"[...] listening to music with fun factor!”

Conclusion

“With their sleek, elegant design, they are well suited to any interior and make an especially high-end impression with their metal accents. When it comes to the sound, the Cubes round it all off […] with a warm and distinct soundstage and punchy bass playback. The setup is, as expected, easily accomplished and even the controls made a good impression [...]“

"Intuitively controlled streaming loudspeakers with a balanced, three-dimensional sound."
HifiDigital 4|2014

"The Cubes are equipped with a 2-way loudspeaker system in a coaxial arrangement. [They have] a standby switch at their disposal that reduces energy consumption to a commendable level of much less than one watt.”

"In our listening room, the Cubes above all impressed us with their amazing three-dimensionality. [...] Tonally, both pairs [The Raumfeld Speaker L and the Raumfeld Cubes] play as if cast from a single mold. This is especially important with multiroom applications. For their tiny enclosure, they sound […]  astoundingly powerful and even reach good depths with their bass. […]

"While setting up our test chain across two listening rooms and an office, we were able to appreciate how well thought out and developed the Raumfeld concept works: Armed with many intelligent and detailed solutions and a self-explanatory setup, we were quickly able to get the system in working order [...]. This system not only offers exceptional sound, but is great when it comes to handling.”

Conclusion:

"Intuitively controlled streaming loudspeakers with a balanced, three-dimensional sound. [...] An open system architecture means it works with practically every network.“

"The Cubes mean business."
einsnull 4|2014
"The cubically formed loudspekaers are very attractive and use coaxial drivers for sound reproduction. There’s a four channel amplifier in the left loudspeaker. Both of the coaxially arranged drivers are supplied with power via bi-amping technology. The Cubes mean business.“

"Setting up the system is wonderfully easy. One simply needs to push a button. The app then searches the network on its own for clients located there and adds them as playback sources. [...] The Cube and all other Raumfeld streaming devices are thereby able to fish just about any playback material from the network that one makes available there. There are no compatibility problems.”

"[F]rom a technical viewpoint, everything’s in top form: Music files up to a 192kHz resolution and 24 Bit can be played. [T]he strength of the Raumfeld System is in the well though-out controls, the truly advanced multiroom function, [and] the ease with which the system can be expanded. And the app is, naturally, constantly improved.

If you want to quickly play some music you have saved on your smartphone on The Cubes, you can do this at the push of a button. Both of the coaxial systems are point source and the level stability of these speakers is top […] – impressive […]. For contemporary people who anyway only want to listen to audio files and streamed music, they represent an especially interesting concept. […] It’s also a very commendable offer for the money. You Berliners did it again.”

"With their rich, room-filling sound, the Cubes are a very good choice"
AudioVideoFoto 4|2014
"It’s barely possible to get more sound with less hardware: Together with a smartphone, these loudspeakers, the Raumfeld Cube from the Berlin manufacturer Teufel, can replace a full-sized stereo system. […]
Quick setup

Connections and setup are easy, in part thanks to good operating instructions […] Integration with the home network can be carried out by cable without the need for additional configurations, or per app. The app is available free of cost for Android and Apple smartphones.
Trouble-free omniplayer

After installation, the app shows various available titles, artists, albums, and playlists under "own music“ in the menu. These can be located on a computer within the home network [or] on a network hard drive […] The Raumfeld speakers aren’t picky about which format the music is in: They play all standard formats like MP3, AAC, WAV and WMA, in addition to less common ones like Ogg and FLAC. Even high resolution (up to 24 bit) poses no problem.
Hidden loudspeakers

One shouldn’t be fooled by the transparent grilles with their golfball sized diameter […] In the middle of the bass membrane of each speaker is a tweeter. This arrangement enables an especially even dispersion. Teufel endows each driver with its own amplifier […]
Supple app

Navigating through the music is effortless and fast, and thanks to an album cover display, it all looks quite nice. The app allows the Raumfeld speakers to be controlled in multiple rooms. According to one’s needs, different music can be played in every room or the same songs everywhere […]
Spacious sound

Those who expect rather thin sound from the Cubes will be pleasantly surprised, because the Cubes sound much larger than they are. […] Voices are reproduced naturally and without colouration, and the bass is amazingly deep and remains crisp and differentiated even at high volumes. One would, in any case, expect much larger speakers with a full sound […]
Conclusion

With their rich, room-filling sound, the Cubes are a very good choice […]  The wide stereo panorama can be counted among its greatest strengths. […]"

Raumfeld Stereo Cubes review of Audio
Raumfeld Stereo Cubes review of Audio
"The set proved itself to be mighty, extensive, and capable of building a strong soundstage"
Audio 03|2014
 "[...] Raumfeld has packed a complete system into a timeless Bauhaus style and calls it – appropriately, enough – the Cube [renamed as The Stereo Cubes]. The Berlin streaming experts have hereby constructed the ultimate space-saving entry level hi-fi drug with the exceptional advantage of being able to play high resolution content with a sampling rate of up to 192 kHz with ease.

On top of this, there’s gapless streaming [...] as well as an intuitive and extremely informative control concept that makes child’s play of sophisticated multiroom streaming down to the last detail.  [...T]he truly style conscious can place the Cube on a bookshelf or end table without the wife complaining – it looks that good thanks to its white lacquer enclosure.

As soon as the compact mini speakers are set up, they can be connected to the home network. Within minutes, the Cube will start scanning [...] the music resources available on a NAS  [...].  The Cube can also pull content from smartphones, tablets, or external USB storage devices/pen drives.

Thousands of radio stations via TuneIn expand the offerings. Music streaming services like Napster, Simfy, MTV Rhapsody [...] are included. Everything is controlled with an intuitive and graphically well executed Raumfeld App for iOS and Android. A practical feature is the line input: It not only receives  external analogue signals, but converts them into digital signals and sends them to other Raumfeld devices in the home via the network  [...]

Front-facing double bass reflex vents allow the speakers to be positioned against the wall. Even the neutral tuning without excessive bass has been optimized for this most practical placement option. The internal workings are equally [...]  high-tech. A WLAN antennae – invisible from the outside – ensures fast 802.lln (150 Mbit) streaming, while the ARM Cortex A8 processor ensures fast reactions on the control surface and smooth browsing through music databases or media libraries of up to 150,000 songs. Whether with HiRes music [...] CDs or MP3s, the Cube leaves no acoustic stone unturned.

The song „745“ from Kosheen (Solitude) played with astonishingly breadth. There were no overdone effects in the upper range and the voice reproduction was pleasant, the Cube impressed above all due to its enormous dynamics and directness.  The set proved itself to be mighty, extensive, and capable of building a strong soundstage with Rachmaniovs Piano Concerto No. 3 in D minor and had a full-fledged sound that could also be plenty loud when required."

"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.”

"totally blown away"
tweak.dk 03.09.2015
I really don't have much to say here today. The Raumfeld Stereo Cubes are just the right music speaker for me, and anyone else looking for explicit and sharp quality sound and a solid bass for the designer living room. I am totally blown away by the Stereo Cubes and even though the price indeed are in the high end I actually find it reasonable. You really do get what you are paying for! I can't do anything else than give the speakers a score of 10 out of 10 and an Editors Choice Award.
 
Pros:

    • Incredibly nice and clean design
    • Loads of effect; 160 watts in total
    • Easy to use setup via mobile app
    • Brilliant sound and nicely adjusted bass level
    • Support for TuneIn and Spotify Connect
    • Everything just fits perfectly!

Cons:

    • I can't really find anything

Score: 10 + Editors Choice Award

Raumfeld Stereo Cubes review of Trusted Reviews
“Wireless technology meets stark German design in Raumfeld’s impressive streaming system”
Trusted Reviews 15.04.2015
What are the Raumfeld Stereo Cubes?

[...] They're a pair of cube-shaped speakers – one active, one passive – that deliver true stereo sound, which is unusual in the streaming speaker market. But an even bigger selling point is their ability to stream lossless audio formats like FLAC and WAV in their native form, without converting them to lower quality as some streamers do.

Raumfeld Stereo Cubes – Design

Much like fellow German audio brand Teufel – which acquired Raumfeld in 2010 and has won plenty of plaudits from Trusted Reviews over the years – Raumfeld’s goal is to deliver audiophile sound quality without the wallet-busting prices normally associated with high-end hi-fi, something it achieves by selling products direct to consumers through its website.

And like its stable mate, Raumfeld places an emphasis on high-quality design, which means the Stereo Cubes are both attractive and beautifully made. The robust MDF cubed cabinets sport a tactile lacquered finish and thick rubber feet on the bottom to quell vibrations. At 195mm wide by 195mm deep, they're compact enough to sit on furniture or shelves without much upheaval.

There’s something delightfully Teutonic about the stark styling, rigid lines and striking silk white finish, although if white's not your thing then they also come in black. The front is covered in black cloth with a silver-ringed mesh dome in the centre, behind which lurks a midrange driver and tweeter in a coaxial arrangement (the tweeter sits in the middle of the midrange driver).

A sloping silver panel adorns the bottom of both speakers, but on the active (left) cube it plays host to the volume buttons. The left speaker also features an unlabelled on/off button and two small lights that indicate the power and system status. On the back of the left speaker you’ll find analogue stereo inputs to hook up devices the old fashioned way. If you connect an analogue source to these inputs, the integrated converter turns it into a digital signal that can be sent to other Raumfeld devices in a multiroom setup.

You also get Ethernet and USB ports, the latter allowing you to play music from storage devices. Also on the back are reset and setup buttons, plus a 6.3mm output that sends audio to the Slave speaker using the supplied cable.

Raumfeld Stereo Cubes – Features


The master Stereo Cube contains the Wi-Fi module and two-channel Class D amplifier, which supplies 80W to each speaker. The speakers use a 28mm fabric tweeter and 130mm midrange driver in a two-way design, alongside a bass reflex system with two vents on the front of the speaker (which you can see if you remove the cloth grille).

The Stereo Cubes support a wide range of audio formats, including MP3, WMA, WAV, AAC, FLAC, OGG and ALAC, with support for sample rates up to 192kHz (provided your router has the necessary bandwidth) and gapless playback.

You can play music stored in your Android or iOS device or stream it from PCs, NAS drives or other UPnP/DLNA music servers. At the time of writing, Spotify, WiMP, Napster Last.fm and TuneIn radio were available through the app, but Raumfeld is planning to incorporate other services in the future. [...]

Raumfeld Stereo Cubes – Setup & Operation


Streaming speakers can be a pain to set up compared with traditional hi-fi systems, but to Raumfeld’s credit the Stereo Cubes are relatively easy to install. You have to download Raumfeld’s app onto your smartphone before you start, which includes a helpful setup wizard that takes you through the process step-by-step.
[…] the app itself is attractive and easy to use. Its clean, logical design and tile-based home screen make navigation a cinch. Operation is slick, and interaction with Spotify is seamless.

Music is arranged into lists with artwork thumbnails at the side and different sorting options at the top. It even downloads pictures of the artists in your library, which is a nice touch. You can search your library by keyword and create playlists. Play a song and it expands to full screen with larger cover art and playback controls.

The app also lets you configure multiroom playback, allowing you to assign different colours, rename speakers and tweak the EQ for each device. You can also swap the speaker channels, or make both play the same channel.

Raumfeld Stereo Cubes – Performance

Raumfeld offers an eight-week trial for all its products with a no-quibble returns policy if you’re not happy. But after hearing the Stereo Cubes in action we doubt you’ll take them up on it. The Cubes’ sound is deeply impressive, high on refinement and power with a pleasing balance across the frequency range.
At the bottom end, bass is tight, propulsive and seamlessly integrated. Playing Dutch band Tristan’s 2nd Phase album on Spotify, the Cubes convey the funky, intricate basslines with astonishing agility, locking every pluck tightly to the drum beat. The groove has depth and heft but it’s not overpowering.

That allows other elements of the music to shine through, such as the crisp brass licks and sparkling percussion. Cymbals crash and slide with impressive precision and clarity, without sounding forced or unnatural. We could pick out the rattling edge of every snare drum hit, and vocals have a pleasing tone. The single-point driver arrangement works well in this respect, resulting in a direct and focused sound. Detail clarity gets even better with hi-res music. We streamed a 96kHz/24-bit FLAC file of All Will Surely Burn by Sons of Kemet and the Raumfeld brings the extra detail to the fore, adding vigour to the drumming and a raspy texture to the meandering trumpet solos. The whole thing has a live, in-the-room feel.

And with two Cubes providing a stereo stage, imaging is terrific. Instruments are clearly and accurately organised within the track’s spacious stereo landscape, making sense of the complicated production. The speakers have enough puff to fill a large room, which will serve you well during parties, although they do lose some of their composure when you turn the volume up loud. […]

Should I buy the Raumfeld Stereo Cubes?

With their stark, eye-catching German design and polished sound quality, the Stereo Cubes are an impressive streaming proposition. Hi-res support and multiroom functionality will win them plenty of fans, while the true stereo setup steals a march on similarly priced mono systems.
The price may look steep on paper, but it’s fairly reasonable considering how much some companies would charge for a system of this calibre. [...]

Verdict

Wireless technology meets stark German design in Raumfeld’s impressive streaming system, which boasts high production values and a polished performance.

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.
