In such a small enclosure, there is clearly not much space for drivers. Small drivers usually mean small sound. That is, unless the drivers have exceptional excursion, a measure of the driver’s mobility. Naturally, Teufel engineers employed premium high-excursion drivers capable of pushing a lot of air from a little space. The result is high, distortion-free levels and an extraordinary bass response. The integrated class D amplifier works efficiently and silently, producing a neutral sound without colouration.
