HELIX Ci3 C100.2FM-S3 MK2

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 loudspeaker reimagined

Performance Highlight

The i3 coaxial systems offer everything you could want from a 2-way system: a first-class sound experience that, thanks to high-quality materials and particularly smart engineering, is very easy and convenient to install in your car. All components are ideally matched and, together with our HELIX and MATCH amplifiers, form the perfect team, guaranteeing maximum performance and power output at all times. Furthermore, our new mechanical technologies, with a clear focus on safety during connection and operation, have been implemented, creating ideal conditions for integration into the vehicle with maximum compatibility.

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.

Cenosphere Paper Cone

In 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. This results in an exceptionally stable yet lightweight diaphragm, offering 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 further reinforced with glass beads. The result: maximum stability with minimal resonances, 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.

Natural Brilliance and Precise Detail Resolution

The 20 mm tweeter features an elegant aluminum dome with a black finish, which impresses with its perfect balance of low weight and high rigidity.

In combination with the redesigned, highly efficient neodymium magnet system, even more precise, clear, and detailed high-frequency reproduction is achieved. The result is natural brilliance with the finest resolution and impressive dynamics – for a listening experience of the highest caliber.

FlexMount100 – Universal meets vehicle-specific

FlexMount is a patented mounting system based on specially developed adapter rings, which allows 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 at all. Using the matching, double-sided lockable FlexMount100 ring, it can be easily and acoustically optimized for installation in the original mounting position of any vehicle. FlexConnect – One terminal for all applications. The FlexConnect terminal allows HELIX COMPOSE speakers to be easily connected directly to the vehicle's original wiring harness, thus maintaining the automotive standard of the connector and also ensuring protection against reverse polarity, among other features. Similar to our FlexMount system, vehicle-specific adapters are used here.
