The finest technical components Our Teufel engineers went all out, not just to make a streaming system, but to make a sound device of the absolute highest class. The most important premise being an extraordinarily linear playback over a very wide frequency spectrum. With Raumfeld by Teufel you get full enjoyment from high definition audio data in 24 Bit and 96 kHz. Raumfeld technology is ranked among the absolute best sounding streaming operations.
Professional-Quality Digital Analog Converter The starting point for this sophisticated signal chain is derived from the professional audio digital-analog converters from CirrusLogic™. It delivers the signal by use of an efficiently working amplifier with total output of 170 watts. The exceptionally low noise amplifier creates clash-free and crystal clear sound. By the way, you save money on the additional amplifier you won’t need to buy…
Top Class Acoustic Components The finely tuned 3-way frequency crossover now amplifies signal on each of the two subwoofers with Carbon cones, a 130 mm midrange driver and a 28 mm tweeter. All chassis impress over a wide frequency range and high dynamic range thanks to considerable stroke. Due to the deep, precise bass reflex tuning the frequency range extends all the way down to 42 Hz.
Direct Control 
The front of the music device is decorated with a decorative aluminum inlay. Here you can manually change the volume of your speakers. This function is, naturally, also available with the Raumfeld App or remote control. A status LED signals information about the device’s operating status.

You can listen to all of the music in the world with just a few clicks. Enjoyment of the music will not suffer, because you can listen to your music in CD-or even better quality (depending on the source material). Listen to music from different sources as you put together your individual multi-room set.
