Helix Compose i7 Ci7 T20FM-SC Tweeters 0.75 Inch 20mm FlexMount Silk Dome
HELIX Ci7 T20FM-SC
HELIX COMPOSE. The perfect speaker for any composition.
Born out of the increasingly demanding challenges of modern automobile technology and the HELIX-typical pursuit of intelligent solutions, we made the progressive redesign of proven universal speaker systems our mission. The result: our innovative HELIX COMPOSE platform that, according to the motto "developed inside the vehicle, for the vehicle", combines classic universal speakers with the advantages of vehicle-specific systems.
Innovative materials and the latest technologies paired with smart, practical engineering - the best of both worlds in harmony: high efficiency, fantastic sound quality and enormous dynamics that fit in any vehicle. HELIX COMPOSE - universal speakers evolved.
i7 – High-end Car Audio made in Germany
Our HELIX COMPOSE i7 series represents uncompromising high-end for an outstanding sound experience in the automobile. With obvious influence of the high-end sister brand BRAX, the i7 speaker series is completely made in Germany and optimized for uncompromising music enjoyment. All speaker impedances are perfectly matched for the combination with our HELIX and MATCH amplifiers, guaranteeing maximum performance at any time. In addition, HELIX COMPOSE introduces four new mechanical technologies that offer unbeatable practical benefits.
Brilliant treble response
Our i7 tweeter is equipped with a fine-meshed silk dome with visco-elastic Acronal coating on both sides, guaranteeing a brilliant and smooth treble response. In addition, the integration of pure lamb’s wool and dampened coupling volume enables a very low resonance frequency and allows a deep acoustic coupling.
FlexMount20 – Universal meets car-specific
FlexMount is a mounting system based on specially developed adaptor rings, allowing the installation of COMPOSE FlexMount speakers in an almost infinite number of vehicles. Thus, the universal tweeter effortlessly becomes a vehicle-specific tweeter, that can be easily installed in the original installation position of the vehicle in an acoustically optimized way with the matching FlexMount20 adaptor ring.
WireKits – Plug & Play at its best
Our WireKits realize the connection of HELIX COMPOSE components to the original wiring harness, or optionally to the crossover, in the most comfortable way. With manufacturing according to the high standards of the automotive industry, these arrestable adaptor cables meet all requirements for the harsh environmental conditions that installers are facing in vehicles every day.

The speaker baskets are made of a high-tech polymer composite, which is additionally reinforced with glass beads for maximum rigidity and minimum ringing
The 100 mm / 4” COMPOSE speaker particularly stands out due to its flat design and large diaphragm area and its extraordinarily powerful, highly efficient push-pull nodymium magnet systems, delivering a dynamic, controlled midrange reproduction.
The super-wide dispersion tweeter is equipped with a fine-meshed silk dome, guaranteeing a brilliant and smooth treble response. In addition, the integration of unique acoustic insulation materials and dampened coupling volume allows a deep acoustic coupling.
Our i7 crossover offers maximum flexibility with many configuration options and is therefore suited for any combination of tweeters and midrange / woofers, assuring an easy and professional integration. The “Flex-Crossover” design, enables an installation with separate tweeter and midrange / woofer mounting positions.
