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.

Test the One S for up to 8 weeks. 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.

High Fidelity Streaming

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.

    Great sound and easy to useI bought this for my kitchen to replace old PC speakers. I thought I needed two but once can easily fill the room with music. Design of the speaker is also really nice and fits.
