HELIX COMPOSE is the perfect speaker for any configuration

Born from the increasingly challenging demands of modern automotive technology and HELIX's typical pursuit of intelligent solutions, we have made it our mission to innovatively redesign proven universal speaker systems. The result: our innovative HELIX COMPOSE platform which, under the motto "developed inside the vehicle, for the vehicle", combines classic universal speakers with the advantages of vehicle-specific systems. Innovative materials and cutting-edge technologies combined with intelligent and practical design: the best of both worlds in perfect harmony: high efficiency, exceptional sound quality and extraordinary dynamics, suitable for any vehicle. HELIX COMPOSE - evolved universal speakers.

Main features

The i3 component systems offer everything you would expect from an excellent 2-way system: First-class sound experience that, thanks to the use of high-quality materials and its particularly intelligent design, integrates perfectly into the cabin. All components harmonize perfectly and form an ideal team with our HELIX and MATCH amplifiers, guaranteeing maximum performance and output power at all times. Furthermore, we have implemented our new mechanical technologies with a clear focus on safety during connection and operation, in order to create ideal conditions for integration into the vehicle with maximum compatibility.

Designed for vehicle-specific adapters FlexMount165 and FlexMount20, available as optional, which allow acoustically optimized and professional integration in the original mounting positions of the vehicle.

High efficiency

HELIX COMPOSE is synonymous with cutting-edge engineering and, consequently, implements a highly efficient 3 Ohm technology that harmonizes perfectly with all HELIX and MATCH amplifiers and, at the same time, guarantees a clear improvement in terms of efficiency and maximum sound pressure. Some models will also be available in optional 2 Ohm variants, ensuring maximum performance and power of the respective speaker in combination with the appropriate amplifier.

"Cenosphere" paper cone

Thanks to the innovative "Cenosphere" coating, hollow spheres are incorporated into a polyamide layer applied to the cone. This process increases rigidity and also optimizes internal damping. The result is an exceptionally stable yet lightweight cone that offers extraordinary precision in sound reproduction.
