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.

Perfectly separated

Our Ci3 FX-UNI.2 crossover is designed for the ideal use with our HELIX Compose i3 components, and thus for the COMPOSE-typical, professional integration into the vehicle It offers a 6-stage tweeter level adjustment with 12 dB slope for optimal adaptation to the installation position as well as an integrated tweeter protection. In addition, no effort was spared in the complex tuning of the crossover for the best possible distribution of the frequency band and a harmonious sound image. Thanks to its compact dimensions, the Ci3 FX-UNI.2 is perfectly suited for installation in tight spaces and is furthermore 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.
