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.

Price-performance highlight

Our HELIX COMPOSE i3 series is an absolute price-performance highlight, providing a first-class sound experience thanks to high-quality components and smart engineering. As you already know from our i7 series, our new mechanical technologies with unbeatable practical benefits, are implemented here as well. All speaker impedances are perfectly matched for the combination with our HELIX and MATCH amplifiers, guaranteeing maximum performance at any time.

High efficiency

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. Certain models will also be available as an optional 2 Ohm variants, assuring the absolute maximum performance and power of the respective speaker in combination with the appropriate amplifier. 

Cenosphere paper cone

With the innovative "Cenosphere" coating, hollow spheres are incorporated into a polyamide layer that is applied to the cone. This process increases the stiffness and also optimizes its internal damping. The result is an exceptionally stable yet lightweight cone that offers outstanding precision in sound reproduction.

High-tech polymer basket

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.

FlexMount165 – 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 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 FlexMount adaptor ring.

ProConnect – The new industry standard

Our innovative ProConnect terminal is the new industry standard: A professional, automotive connector, allowing the safe use of conventional speaker cables, while also being ideally designed for connection via flat plug with our WireKits, offering maximum flexibility in the design of the sound system upgrade. Furthermore, the connection is interlocked, offers reverse polarity protection and is electrically and mechanically highly stressable.

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.

LOVE THEM🩷
Size: 10FT, Color: Pink
Love these charges so much and have been using them for years! However, each charger only lasts about 6 months. I think they are worth it though and very good. It comes with two so you only need to buy a new pack once a year. Most chargers nowadays don’t last anyway. These charge fast and are very long. Also love the color options, I have mine in pink🩷

Long Cables and Easy to Spot
Size: 10FT, Color: Blue
So far these have been great chargers. They charge quickly and we have not had any issues with them overheating or causing problems with our iPhones, which is always my main concern with third party chargers. The 10 foot length is a big plus. It gives plenty of flexibility whether you are on the couch, in bed, or working at a desk. The extra length makes a noticeable difference compared to standard cables. I actually bought the blue set for my wife so her chargers would stand out from all the white ones around the house. That has worked perfectly. They are easy to identify and no one else grabs them by mistake. The two pack was ideal for that reason, giving her one for the bedroom and one for another room. If you are looking for a fast charging option with longer cables and want something that is easy to distinguish from the usual white cords, this is a solid choice.

Great block & cables!
Size: 10FT, Color: White
Chargers work fantastically! Charges iPhone 16 superfast as well as new larger iPads. I’ve also used it to charge my MacBook Pro, which it works well with that as well. Doesn’t seem to get excessively hot and the cables are of high-quality. Have bought a lot of these so far and love them!
