Sound quality meets elegance – The new S speaker series turns every ride into a special sound experience.

In addition to the novel, timelessly elegant design, the 2-way coaxial system offers an exceptional sound quality. Uniquely sensitive and crystal clear, the silk dome of the tweeter conjures the music into the room. Due to its central position inside the mid-woofer, the music is perceived as a point sound source and thus optimizes the tonal balance. The result: an incredibly homogeneous and natural sound.

The stiff and lightweight diaphragm of the mid-woofer consists of a novel basalt fiber paper compound. A perfect combination to guarantee clear, pure sound even at high volume levels. In conjunction with a power amplifier from Audiotec Fischer, the S coaxial system performs at its best.
