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.
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.
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.
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.

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.
HELIX COMPOSE equals smart engineering and accordingly implements highly efficient 3 Ohm technology, that perfectly harmonizes with all HELIX and MATCH amplifiers and at the same time allows a clearly perceptible plus in efficiency and maximum sound pressure.
With notable influence from the sister brand BRAX and our uncompromising high-end philosophy, only the highest quality components, such as the proprietary, handmade UHD (Ultra High Damping) paper cone, are used in the i7 series. manufactured in a particularly complex process, this cone guarantees an optimal frequency- as well as the best possible impulse response for incomparable music enjoyment.
All HELIX COMPOSE i7 and i3 speaker baskets are made of a high-tech polymer composite, which has been additionally reinforced with glass spheres. The result: maximum stability with minimal self-resonance, while also eliminating flux modulation of the magnetic system and maximum resistance to thermal influences. Last but not least, this allows for much more compact basket dimensions and thus simplified installations in cramped installation conditions.
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 loudspeaker effortlessly becomes a vehicle-specific loudspeaker, that can be easily installed in the original installation position of the vehicle in an acoustically optimized way with the matching twist-lock FlexMount100 adaptor ring.
With our FlexConnect terminal, HELIX COMPOSE speakers can easily be connected directly to the original wiring harness of the vehicle, maintaining the automotive standard of the plug connection as well as guaranteeing reverse polarity protection. Similar to our FlexMount system, this technology relies on specially developed, vehicle-specific adaptors.
