A small, modular powerhouse

A little speaker that makes a very big impression. A power connection and Wi-Fi access are enough for this little guy to fill even medium size rooms with rich, high-definition sound. A free app allows you to access music from your own private collection as well as streaming services and Internet radio. Alternately, 4 preset buttons allow you to get your favourite streams of music started right away. A volume regulator and on/off switch are also included for directly controlling the system.

The little One S works with a wide range of streaming services as well as your own music collection stored on USB or DLNA enabled devices. You can also send music stored on your smartphone or tablet directly, wirelessly, and losslessly to the One S.

The little One S is jam-packed with high-end acoustic and streaming hardware including:

  • A 2-way coaxial system consisting of a 100 mm midbass driver with forward placed 20 mm tweeter. Not only does this arrangement allow more drivers to be placed in a smaller space, it approximates a point source for an acoustically superior result. The same system used in our Stereo Cubes has garnered the system wide-spread praise for its powerful, clear and detailed sound.
  • A long throw 100 mm midrange driver allows the One S to produce amazingly deep, rich and responsive bass.
  • Side-mounted 80 mm passive radiators give the system an incredible 45 Hz low end.
  • A digital signal processor using a sophisticated equalizer to eliminate any resonances or gaps in the bass range for a nearly perfectly linear frequency response and true-to-source playback. Equalizer presets adjust the sound for the kitchen, bathroom and living room for an optimal sound.

Thanks to a low noise 50 watt class D amplifier, the One S produces incredibly high, distortion-free levels in even larger rooms.

If the One S is combined with other Raumfeld devices, the entire multi-room system can be centrally controlled with the Raumfeld App as well.

Built to last

An aluminium cover adorns the front of the One S. The control buttons are made from pleasantly soft silicone that are perfect for use in a messy environment like the kitchen as it's easy to wipe off a bit of Nutella or jam. Robust fabric covers protect the drivers and rubber rings on the bottom guarantee secure placement.

The One S can be easily wall mounted

Integrated keyhole brackets make it easy to mount the system on a wall. Flexible wall mounts are also available as additional accessories.

Setting up the system is easy and no other devices are needed to make i t work other than a Wi-Fi router and smartphone/tablet.

"The material mix of brushed aluminium on the front and silicone on the control buttons - which renders them water repellent - and matte lacquer on the rest of the loudspeaker makes it not only a visual treat, but gives it a robust and high-end end appearance. The finishing allows it to visually blend into and room and fits in everywhere.”"Considering that the loudspeaker is only the size of a pack of crackers, the output is simply insane. I was immediately impressed by the sound from this little noise maker.”Conclusion:"To sum up, I can only recommend Raumfeld to anyone considering buying a multi-room system. With its unbeatable price and the quality of the workmanship as well as the sound, one doesn’t have to mull over the decision for very long.”

“Before we proceed: I didn’t even need to touch an Ethernet cable. The WiFi setup via the free Raumfeld App worked perfectly.”First impressions"The white loudspeaker looks really good. The matte synthetic enclosure is the product of high-quality workmanship and comes across as very modern and minimalistic. It fit wonderfully into the overall look of our living room. “"I would describe the sound quality as impressive – in every respect. I was blown away by the first listening session. After all, that this small box with the dimensions 11 x 18 x 13 centimeters delivers such a powerful and yet clean sound is simply amazing.“"The bass has incredible power, the highs sound clean and don’t distort at even high volume levels. The One S had no problem filling our 30 square meter living room with sound, and if I turn up the volume any more, the neighbours will no doubt be at my door in seconds.”Conclusion"So small and yet so big: With the One S, Raumfeld has a very good entry level device to its line that, with a price tag of just 250 EUR, is very attractive. The sound is phenomenal for the size and the system can be easily controlled with the app.”Translated from the original German.

Raumfeld One S – Sound Quality "The Raumfeld One S is an impressive-sounding speaker, especially when you consider its diminutive size. In some ways it’s even better than the current leader of the pack, the Sonos Play:1. It uses the same two-way coaxial system as the excellent Raumfeld Stereo Cubes we reviewed recently. The 90mm mid-range driver, 25mm tweeter and two woofers provide a solid sound you’d expect to hear coming from something much, much bigger. We don’t expect hi-fi-quality sound from a speaker this size and price, but music is clear, detailed and packs an impressive punch at higher levels. The One S can certainly fill a medium-sized room with rich, distortion-free sound. Where the Raumfeld falls a little short is the low-end. Bass is a touch limited, even more so than the smaller Sonos Play:1. Unlike the cheaper TrustedReviews Awards-winning Samsung M3, however, the sound never gets muddied on bass-heavy tracks. It remains balanced and clear throughout, if a little weak. Listening to some Tricky and hip-hop albums lacked the low-end oomph that brings that genre to life. At top levels treble can be a little harsh too, but the midrange packs plenty of detail and clarity. These issues are minor – most people not obsessed with audio fidelity will be thoroughly impressed with the power and sound quality of Raumfeld’s little marvel. Overall we ever so slightly prefer the One S to the Sonos and Samsung, both in terms of a balanced sound and top volume level. If you’re into bass-heavy tracks, though, the Sonos or Samsung may be better bets."

It’s really astonishing what the sound engineers managed to pull off here.”"We’ve had larger loudspeakers in for testing that didn’t come close to sounding as good as the Raumfeld One S. Its soundstage is very lively and harmonious with finely differentiated highs, a natural midrange and exceptionally far-reaching depth. On top of this is a level stability that we would never have suspected in this small of a loudspeaker.”Conclusion"The Raumfeld One S fits in perfectly in a living room environment thanks to its chic and compact design.“"[...] excellent sonic qualities [...]“"[...] by the very first listening test at the latest, the little loudspeakers will have won over the hearts of the biggest sceptics.

"The first spontaneous question: Where on earth did this rich bass come from? One wouldn’t have expected it from the little pipsqueak. Even in smaller to mid-sized living rooms, the One S is capable of a proper room-filling sound with precise highs and clean bass.” "The Raumfeld newby reproduces voices clearly and without distortion. The speaker even overflows with dynamics with quick concert sequences  […] and doesn’t doesn’t lose its rhythm.”"The One S puts across a very mature performance – neither overly playful nor was it designed as a compromise. Naturally, the bass can’t compete against larger loudspeakers. The maximum levels are not infinite, but to criticize this would be like wondering why a VW Polo doesn’t stand a chance against a Porsche Carrera. High-resolution files  [...] are processed by Raumfeld in excellent sound quality."Translated from the original German.

"Teufel’s acquisition of Raumfeld proves what good instincts it has. The tested introductory product, the Raumfeld One S is absolutely on the same level as its competitors from Sonos & co. and this even applies to the features and level of quality. The precise and bass-driven sound that the mini loudspeaker is capable of reproducing is especially impressive. But even smaller details like the rubberized buttons for safe playback in bathrooms or the possibility to turn off the status LEDs for use in the bedroom makes the Raumfeld One S an absolutely top product. The only real point of criticism is that a LAN cable is required for the setup (Wi-Fi!). On the other hand, the Raumfeld One S can be purchased for just 250 Swiss francs. Raumfeld devices, like the other Teufel devices, are exclusively available for purchase online.”Translated from the original German.

"During setup and operation, one quickly realizes that truly smart people got together on this one. The connections on the back side are recessed so that no plugs protrude which would take up more space.”"In spite of its mini dimensions, the Raumfeld One S is equipped with high-end technology. A 2-way coaxial system along with two 95 mm bass drivers are included which – together with the powerful 50 watt bi-amped amplifier produces, considering the size, a very good and homogenous sound that doesn’t fall short in the bass range and which fills the room dynamically and with precision. Oh, and the One S can be loud, too!”Conclusion"The Raumfeld One S is an ideal and reasonably priced introduction to the Raumfeld world - or a quick and uncomplicated way of expanding an existing system.

"As one has come to expect from Raumfeld, the One S is a technologically exceptional device. The moment you touch it, it becomes clear that you're dealing with a quality product and not another plastic box masquerading as a loudspeaker. The enclosure is well made, the design and the entire device, minimalistic. And for exactly this reason, the One S can be integrated into practically every living or working environment without making itself conspicuous [...].“"The sound quality is best described by the adjective 'impressive' and that in every respect. After turning the device on, one is immediately blown away by the fact that a speaker with the dimensions 11 x 18 x 13 centimeters can deliver this sort of powerful and yet clean sound. “"Once you recover from the shock and listen more closely, you notice that Raumfeld really does its job. The One S contains a tweeter, a midbass and two bass drivers. All-in-all, the ensemble delivers maximum sound pressure up to 101dB/1m – enough to fill even full-sized living rooms with sound. A 50 watt bi-amping amplifier ensures high volumes along with dynamic bass performance.”Translated from the original German.
