HELIX COMPOSE. The perfect loudspeaker for every composition.

Born from the ever-increasing demands of modern vehicle technology and HELIX's signature pursuit of intelligent solutions, we made the advanced redesign of proven universal loudspeaker systems our mission.

The result: The innovative HELIX COMPOSE platform, which, guided by the principle "designed in the car, for the car," combines classic universal loudspeakers with the advantages of vehicle-specific systems. Innovative materials and cutting-edge technologies paired with smart, practical engineering – the best of both worlds in perfect harmony: very high efficiency, fantastic sound quality, and tremendous dynamics that fit any vehicle.

HELIX COMPOSE – Universal loudspeakers reimagined.

The sound sensation for discerning music lovers.

FlexMount80 – Universal Meets Vehicle-Specific

FlexMount is a mounting system based on specially developed adapter rings that allows COMPOSE FlexMount speakers to be installed in a virtually unlimited number of vehicles. This transforms the universal speaker into a vehicle-specific speaker in no time, enabling easy and acoustically optimized installation in the original mounting position of any vehicle using the appropriate FlexMount ring.
