The form of B 100 is taken and reminded to the aircraft construction of the aerodynamically clean bearing areas of large airplanes. New technical realizations flowed into the development. Measuring techniques of most modern kind helped with the development to exclude also smallest errors. The time-correct rendition and high dynamics those the live representation corresponding were demands in the obligation booklet of the B100. The result is a graceful designed loudspeaker, which can be integrated despite its size harmoniously into each living room and at the same time the gates to the benefitful music rendition opens. The B100 is a three-way full-range loudspeaker with built-in phaserigid passive crossover with filters of first order. Bass-, mid-range and high-frequency drivers are arranged in a d’Appolito configuration. The cabinet of the B100 is double-walled.
