HELIX Ci3 W165FM-S2

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, following 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 harmony: very high efficiency, fantastic sound quality, and enormous dynamics that fit into any vehicle. HELIX COMPOSE – universal loudspeakers reimagined.

Price-Performance Highlight

Our HELIX COMPOSE i3 series is a true price-performance highlight, delivering a first-class sound experience thanks to high-quality components and smart engineering. As with the i7 series, new mechanical technologies are implemented here as well, offering unparalleled practical benefits. All speaker impedances are perfectly matched to our HELIX and MATCH amplifiers, guaranteeing maximum performance and power output at all times.

Maximum Efficiency

HELIX COMPOSE stands for smart engineering and is therefore based on highly efficient 3-ohm technology, which harmonizes perfectly with all HELIX and MATCH amplifiers and simultaneously enables a noticeably increased efficiency and maximum sound pressure level. Individual models will also be available as an optional 2-ohm version, which, in conjunction with the appropriate amplifiers, extracts the absolute maximum performance and power from the respective speaker component.

Cenosphere Paper Cone

With the innovative "Cenosphere" coating, micro hollow spheres are embedded in a polymer layer and applied to the diaphragm. This process increases stiffness and also optimizes its internal damping. The result is an exceptionally stable yet lightweight diaphragm that offers outstanding precision in sound reproduction.

High-Tech Polymer Composite Basket

All HELIX COMPOSE i7 and i3 speaker baskets are made of a high-tech polymer composite material, which is additionally reinforced with glass beads. The result: maximum stability with minimal resonance, while also eliminating flux modulation of the magnet system and providing maximum resistance to thermal influences. Finally, this allows for significantly more compact basket dimensions and thus simplified installation in confined spaces.

FlexMount165 – Universal Meets Vehicle-Specific

FlexMount is a mounting system based on specially developed adapter rings, which enables the installation of COMPOSE FlexMount speakers in a virtually unlimited number of vehicles. This transforms the universal speaker into a vehicle-specific speaker in no time, which can be easily and acoustically optimized for installation in the original mounting position of any vehicle using the appropriate FlexMount ring.

ProConnect – The new industry standard

Our innovative ProConnect terminal reflects the new industry standard: It is a professional, automotive connector that allows the safe use of conventional speaker cables, but is also ideally suited for connection via flat connectors with our WireKits, thus offering maximum flexibility when designing your sound system upgrade. Furthermore, the connector is locked, offers reverse polarity protection, and is highly robust both electrically and mechanically.

WireKits – Plug & Play at the highest level

Our WireKits make connecting HELIX COMPOSE components to the original wiring harness or, if necessary, connecting the speaker to the crossover easy.

Manufactured to the high standards of the automotive industry, these lockable adapter cables meet all the requirements for the harsh environmental conditions in vehicles.
