"With the Raumfeld Connector², the Berliners have a network audio player in their product portfolio […] that unites two worlds: The worlds of hi-fi systems and that of music from the internet.”"Due to the use of a Cirrus Logic D/A converter chip, the quality of the analog output is very satisfactory. The bass that is delivered to the amplifier is rich and the treble thoroughly nuanced, the stereo image is detailed and is a lot of fun to listen to.”"Raumfeld systems offer a well-executed introduction to the world of multi-room streaming. [T]he Berliners offer a good system that can be effortlessly extended and which can continue to be enjoyed in the future. Devices with similar qualities [...] can only be found in a higher price class. Ever the Raumfeld Connector²‘s sound is a winner."

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 anythingScore: 10 + Editors Choice Award

Raumfeld & Teufel devices distinguished in the Video, Stereoplay and Audio reader’s choice awardsAt the start of 2015, all products tested during the previous year by the publications Video, Stereoplay and Audio were nominated for the acclaimed reader’s choice award.We’re very happy to report that the readers of these publications once again chose our products for multiple first and several second place awards. Among them were the Raumfeld Stereo Cubes which was awarded first place in the category “Wireless Speakers.”Translated from the original German.

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.”

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 – DesignMuch 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 – FeaturesThe 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 & OperationStreaming 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 – PerformanceRaumfeld 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. [...]VerdictWireless technology meets stark German design in Raumfeld’s impressive streaming system, which boasts high production values and a polished performance.

Test result: Very good Price / performance: Very good

"These graceful streaming loudspeakers combine the faultless functionality of Raumfeld’s streaming architecture with the loudspeaker know-how of Teufel. In this way, one’s own music collection as well as plenty of entertainment from the worldwide web can be directly accessed by the loudspeaker. The result is fine sound with simple and convenient operation.”

 [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.

"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.”

"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.“

"[...] 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."

“The streaming division of Teufel Audio has been around for just three years. Their product range extends from streaming loudspeakers and small routers to NAS systems and controllers – in other words, the whole streaming program. The new Connector 2 extends the existing hi-fi range to include smart streaming abilities.” “The Berlin loudspeaker manufacturers and home cinema experts Teufel acquired a highly competent team with Raumfeld GmbH [...]. Since then, smart active speakers with integrated streaming and components that enable an expanded and user-friendly music network have been produced. One thing should be made clear: With respect to network stability, Raumfeld components are ahead of the pack.”“While many still shy away from networks, IPs, or UPnP servers, there’s no talk of that here. It doesn’t matter what network structure you have at home or where your music is stored. This little box is like an additional player for your system and can be attached via cinch cable or digital Toslink. The network connection is made via LAN or Wi-Fi. [...] Set up is child’s play. All connectors, Raumfeld streaming speakers, and UPnP devices in the network can be configured via the app and then made available to existing music archives.”“Thanks to the very best Cirrus Logic converter, the sound streamed by the connector is truly amazing. Every type of music is played clearly with fine resolution and solid, highly accurate dimensionality. Another device in this or an even higher price class has yet to reproduce this quality. One thing’s for sure: The Raumfeld system was and remains the most stable and flexible solution for network streaming out there.”Conclusion“Whoever’s considering streaming, but is afraid to commit no longer has an excuse. The Raumfeld Connector 2 is so simple to set up and sounds so good that anyone can expect to derive immediate and long-lasting enjoyment from it.”Translated from the original German.

"[...] This little box gives existing music systems that are not network enabled the ability to stream music and access Internet radio. In addition, it has an optical digital output as well as an analog stereo cinch connection and a line input with a sensitivity that can be regulated per software (app), a LAN interface, and USB port. [...] The on and off switch is located in an easy-to-reach position on the top  [...]. Setup and operation of the Raumfeld Connector can be executed via an optional remote control (Raumfeld Controller) or free app for mobile operating systems Android and iOS.[...] As soon  [...] as the setup assistant is finished, it’s easy to play music from USB storage devices and DLNA servers, accessible computers, and music services like TuneIn, Napster, Simfy, or Last.fm. The current firmware can even handle extremely large music libraries (150,000 files) on network drives and USB devices. As one would expect from a high-end network player, high resolution audio files and gapless playback is supported. ConclusionThe Raumfeld Connector is the perfect partner for systems lacking their own network functionality. The setup is quickly mastered, operating the device is simple, and the sound impressive."Translated from the original German.

"Raumfeld - the name already sounds superior. [...] Three different stereo speaker systems, a one speaker solution and – last, but not least – the Raumfeld Connector for connecting an existing hi-fi system combine to create a product range that just about satisfies every requirement. All components communicate with each other via accessible WLAN through which they also have access to music libraries available in the network [...]. In addition, Raumfeld naturally has command of Internet radio and various streaming services [...].”Conclusion"Those who are not just looking at comfort when it comes to multiroom, but maximum sound quality as well should take a closer look at Raumfeld. The system plays nearly all file formats, including many lossless and high resolution varieties, and therefore guarantees maximum music enjoyment with minimum cabling effort.”

"The Connector [...] plays just about every standard format (MP3, WAC, FLAC, Ogg Vorbis, ASF, WMA, M4A, AAC and Apply Lossless) in all possible sampling rates. It quickly becomes apparent how well thought-out and, above all, universal the Raumfeld system is.” "All this is contained within an attractive synthetic enclosure the size of a paperback. The device has two analog outputs as well as an optical digital output and a USB terminal for USB storage devices. With the current version of the Connector, 192 kHz and 24 bit are not a problem.” "If you get tired of your own music, you can always make use of a pre-installed and thereby quickly accessible music service. [...] Thanks to a serious Cirrus Logic converter, the Connector produces an acoustic result that is simply outstanding [...]. A device in this or higher price class should try to beat it. One this is for sure: The Raumfeld system is and remains about the most stable and flexible solution for network streaming.” Conclusion "Whoever’s considering streaming but afraid to commit has run out of excuses. The Raumfeld Connector2 is easy to set up and has a sound so rewarding that anyone will be instantly and over the long run happy with it.” Translated from the original German.

“Teufel sells its miniature network player for a mere 200 Euros. In exchange, one gets an astonishing array of music possibilities as well as an alluring and extensive introduction into the world of Raumfeld. One namely has the ability to use the Connector 2 in combination with other network players from this manufacturer to build a multiroom connection [...] At first glance, the newcomer appears to be hardly different from its predecessor. The enclosure, however, is compacter. The reason for this is quickly ascertained: The WLAN antenna which was located on the back of the original Connector has been discreetly relocated in the interior of the enclosure. This change earns the new model high marks for style.” “The basic structure of the network player hasn’t been changed by Teufel: The streamer plays music from UPnP or DLNA certified network servers along with NAS drives as well as the music library from any PC with Windows. It’s even capable of supporting sound formats [...] from USB storage devices connected to the back. Those who require more can tune in to tens of thousands of internet radio stations via the TuneIn service or can log in to his simfy or Napster account or make use of the analogue input. Should one possess more than one Raumfeld device, these signals can be streamed into other rooms. Unlike that first Connector, the new model can process a full 192 kilohertz.” Conclusion “It’s fast, easy to operate, sounds good and is inexpensive to boot. With the new Connector 2, Raumfeld gains ground on its main competitors.”

"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 RaumfeldApp: 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 CubeTeufel‘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. […]"Translated from the original German.
