Every detail sets the tone
The plug & play STEREO M 2 sound breathtakingly large, but take very little space while offering an impressive array of streaming options. And all that with no cable between the speakers.
State of-the-art integrated amplifier and DSP components are matched perfectly to all drivers. The overall system thus has greater performance than a comparable passive speaker with external amplifier. Large tweeter to put out silky trebles even at high volumes. The tweeter and midrange driver are fused into a single component, meaning almost all the frequencies produced reach the ear at the exact same time, which makes playback sound particularly natural.
The woofer is wok-shaped and made of kevlar for extra lightness, resistance to warping, and perfect for deep, precise bass with its extreme long throw capacity.
The magic of point-source sound
Here at Teufel, we want you to hear every microsecond of a saxophone trailing off, every key press on a piano, and every overtone of a synthesizer without having to spend a fortune on a HIFI setup.
And that was why we developed the SCA (Synchronized Coaxial Acoustics) flat diaphragm chassis here in our Berlin labs. It functions as a single-point audio source, creating only the most minor distance between the midrange driver and tweeter.
The flat diaphragm does not sonically limit the range of the tweeter. It keeps the vibrating air particles at a single layer and thus obstructs interference. As a result, every audio event comes across as if in reality, as a single-point source. The overall effect is a more realistic and precise experience than can be provided by separate tweeters.
