Helix CI3 C100.2FM-S3 MK2 pair of high-performance 4" / 100mm coaxial speakers with 3 Ω impedance, aluminum tweeter and FlexMount technology

HELIX COMPOSE. The perfect speaker for any configuration.

Born from the increasingly demanding challenges of modern automotive technology and HELIX's typical pursuit of intelligent solutions, we set ourselves the mission of innovatively redesigning 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, fantastic sound quality and enormous dynamics that adapt to any vehicle. HELIX COMPOSE - evolved universal speakers.

Key features

The i3 coaxial 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 vehicle interior. All components integrate seamlessly and form an ideal combination 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.

High efficiency

HELIX COMPOSE is synonymous with cutting-edge engineering and, consequently, implements 3 Ohm high-efficiency technology, which 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.

"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.

FlexMount100 - Universality meets specificity for every model

FlexMount is a mounting system based on specially developed adapter rings, which enables the installation of COMPOSE FlexMount speakers in a virtually infinite number of vehicles. In this way, the universal speaker transforms effortlessly into a model-specific speaker, which can be easily installed in the vehicle's original mounting position in an acoustically optimized manner thanks to the FlexMount100 adapter ring with rotary closure.
