FlexMount200 – Universal meets car-specific

FlexMount is a mounting system based on specially developed adaptor rings, allowing the installation of COMPOSE FlexMount speakers in an almost infinite number of vehicles. Thus, the universal loudspeaker effortlessly becomes a vehicle-specific loudspeaker, that can be easily installed in the original installation position of the vehicle in an acoustically optimized way with the matching FlexMount adaptor ring.

For the comfortable installation of maximum bass upgrades in Mercedes models

The CFMK200 MB.1S adaptor was specially developed for the installation of the Ci5 S200FM hybrid subwoofer in the factory mounting locations of the bulkhead, and thus for maximum bass upgrades in various Mercedes models.
