HELIX Ci3 T20FM-AL 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.

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.

Natural Brilliance and Precise Detail Resolution

The new Ci3 tweeter features an elegant aluminum dome with a black finish, boasting a perfect balance of low weight and high rigidity. Combined with the redesigned, highly efficient neodymium magnet system, this results in even more precise, clear, and detailed high-frequency reproduction. The result is natural brilliance with the finest resolution and impressive dynamics – for a listening experience of the highest caliber.

FlexMount20 – Universal meets vehicle-specific

FlexMount is a mounting system based on specially developed adapter rings, which allows the installation of COMPOSE FlexMount loudspeakers in a virtually unlimited number of vehicles. In no time at all, the universal tweeter becomes a vehicle-specific tweeter, which can be easily and acoustically optimized for installation in the vehicle's original mounting position using the appropriate FlexMount20 ring.

WireKits – Plug & Play at the highest level

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