The speaker baskets are made of a high-tech polymer composite, which is additionally reinforced with glass beads for maximum rigidity and minimum ringing
The 100 mm / 4” COMPOSE speaker particularly stands out due to its flat design and large diaphragm area and its extraordinarily powerful, highly efficient push-pull nodymium magnet systems, delivering a dynamic, controlled midrange reproduction.
The super-wide dispersion tweeter is equipped with a fine-meshed silk dome, guaranteeing a brilliant and smooth treble response. In addition, the integration of unique acoustic insulation materials and dampened coupling volume allows a deep acoustic coupling.
Our i7 crossover offers maximum flexibility with many configuration options and is therefore suited for any combination of tweeters and midrange / woofers, assuring an easy and professional integration. The “Flex-Crossover” design, enables an installation with separate tweeter and midrange / woofer mounting positions.
