HELIX COMPOSE. The perfect speaker for any composition.

Born out of the increasingly demanding challenges of modern automobile technology and the HELIX-typical pursuit of intelligent solutions, we made the progressive redesign of proven universal speaker systems our mission. The result: our innovative HELIX COMPOSE platform that, according to the motto "developed inside the vehicle, for the vehicle", combines classic universal speakers with the advantages of vehicle-specific systems. Innovative materials and the latest technologies paired with smart, practical engineering - the best of both worlds in harmony: high efficiency, fantastic sound quality and enormous dynamics that fit in any vehicle. HELIX COMPOSE – universal speakers evolved. 

Ideal frequency separation and flexible integration options

Our Ci7 FX-UNI.2 crossover is designed for the ideal use with our HELIX Compose i7 components, and thus for the COMPOSE-typical, professional integration into the vehicle. It offers a 4-stage tweeter level adjustment for the optimal adaptation to the installation position as well as numerous lowpass filter adjustment options with 12 dB slope to perfectly match the connected COMPOSE midrange, midbass or woofer. In addition, with absolutely high-quality components and the complex tuning of the crossover, no expense and effort were spared to maintain the best possible distribution of the frequency band, a harmonious sound image and top quality. Thanks to the “Flex-Crossover” design, the Ci7 FX-UNI.2 offers flexible integration options and is well suited for the installation in vehicles with separate mounting positions of the tweeter and woofer. And of course, it’s compatible with our COMPOSE Connect and WireKit technologies for a safe and fool-proof connection according to automotive standards.


Kiss tinkering and soldering goodbye. Compose Connect is the sophisticated plug-in connection that considerably simplifies car audio installation in conjunction with HELIX COMPOSE components. Proprietary plastic housings into which standard flat plugs and couplings can be snapped, establish an absolutely safe connection in accordance with automotive standards that prevents any polarity reversal.

WireKits – Plug & Play at its best

Our WireKits realize the connection of HELIX COMPOSE crossover to the original wiring harness in the most comfortable way. With manufacturing according to the high standards of the automotive industry, these arrestable adaptor cables meet all requirements for the harsh environmental conditions that installers are facing in vehicles every day.
