HELIX Ci7 T20FM-SC tweeter

HELIX COMPOSE. The perfect speaker for every composition.

Born out of the increasingly demanding challenges of modern vehicle technology and the HELIX-typical quest for intelligent solutions, we made the progressive redesign of proven universal loudspeaker systems our mission. The result: the innovative HELIX COMPOSE platform, which combines classic universal loudspeakers with the advantages of vehicle-specific systems according to the guiding principle "developed in the car, for the car". Innovative materials and the latest 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 taken to the next level.

i7 - High-End "Made in Germany"

The HELIX COMPOSE i7 series represents uncompromising high-end for an extravagant sound experience in the car. With a clear influence from the high-end sister brand BRAX, the i7 loudspeaker series is completely "made in Germany" and optimised for unadulterated music enjoyment. The impedances of all speakers are perfectly matched to the combination with our HELIX and MATCH amplifiers, guaranteeing maximum performance and power output at all times. In addition, we have implemented new mechanical technologies in HELIX COMPOSE that offer unrivalled practical benefits.

Brilliant high frequency reproduction

Our i7 tweeter is equipped with a fine-meshed silk dome tweeter with a visco-elastic Acronal coating on both sides, which ensures brilliant, velvety-soft tweeter reproduction. The integrated coupling volume, damped with pure sheep's wool, enables a particularly low resonance frequency and therefore a low acoustic coupling.

FlexMount20 - Universal meets vehicle-specific

FlexMount is a mounting system based on specially developed adapter rings that allows COMPOSE FlexMount speakers to be installed in an almost infinite number of vehicles. This turns the universal tweeter into a vehicle-specific tweeter in no time at all, which can be easily installed in the original installation position of the vehicle with the matching FlexMount20 ring in an acoustically optimised manner.
