Brilliant treble response<br>
Our i7 tweeter is equipped with a fine-meshed silk dome with visco-elastic Acronal coating on both sides, guaranteeing a brilliant and smooth treble response. In addition, the integration of pure lamb’s wool and dampened coupling volume enables a very low resonance frequency and allows a deep acoustic coupling.<br>

FlexMount20 – Universal meets car-specific<br>
FlexMount is a mounting system based on specially developed adapter rings, allowing the installation of COMPOSE FlexMount speakers in an almost infinite number of vehicles. Thus, the universal tweeter effortlessly becomes a vehicle-specific tweeter, that can be easily installed in the original installation position of the vehicle in an acoustically optimized way with the matching FlexMount20 adapter ring.<br>
