HELIX Ci7 T20FM-SC

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.

i7 – High-End Car Audio “Made in Germany”

The HELIX COMPOSE i7 series represents uncompromising high-end audio for an extravagant sound experience in the car. With a clear influence from its high-end sister brand BRAX, the i7 loudspeaker series is entirely “Made in Germany” and optimized for pure musical enjoyment. The impedances of all loudspeakers are perfectly matched to our HELIX and MATCH amplifiers, guaranteeing maximum performance and power output at all times. Furthermore, we have implemented new mechanical technologies in HELIX COMPOSE that offer unparalleled practical benefits.

Brilliant High-Frequency Reproduction

Our i7 tweeter features a fine-mesh silk dome with a viscoelastic, double-sided Acronal coating, ensuring brilliant, velvety-smooth high-frequency reproduction. The integrated coupling volume, damped with pure sheep's wool, enables a particularly low resonance frequency and thus deep acoustic coupling.

FlexMount20 – Universal Meets Vehicle-Specific

FlexMount is a 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 tweeter into a vehicle-specific tweeter in no time, which can be easily and acoustically optimized for installation in the vehicle's original mounting position using the appropriate FlexMount20 ring. Find the right FlexMount for your vehicle now! 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 effortless. Manufactured to the high standards of the automotive industry, these lockable adapter cables meet all the requirements for the harsh environmental conditions in vehicles.
