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 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.

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.

UHD (Ultra High Damping) crafted paper cone

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.

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.

FlexMount100 – 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 twist-lock FlexMount100 adaptor ring.

FlexConnect – One terminal for all cases

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.

A greasy mess
SUPER greasy. I have dry skin and it was incredibly greasy for me. It didn’t dry down at all and felt like it sat/slid around on my face. Obviously goes on clear since it’s a chemical sunscreen. Vaseline gel-like texture in your hand and applies like a silicone barrier. That part makes a little sense since I think dimethicone is high on the ingredient list. Unscented and didn’t test under makeup. I wouldn’t recommend this to anyone and I don’t think I’d try it again, which is disappointing cause I was hopeful with this one after reading reviews! The glowing reviews versus my experience makes me think folks aren’t applying enough SPF to get adequate sun protection. I’m a skincare girlie so it’s always a half teaspoon for this face.

Works well, smells great, goes on easily
Sun protection factor: 15 Sun Protection Factor (SPF), Size: 6 Count (Pack of 2)
It smells good. It goes on easily with the spray bottle. It keeps me from burning while out biking. It's a good price. Overall, a very nice product that does what it should. We carry it in our bike packs and in the car when we know we'll be out in the sun all day. Doesn't feel heavy when sprayed on so it smooths over your skin very well. Keeps me from burning.

My favorite sunscreen!
Sun protection factor: 70 Sun Protection Factor (SPF), Size: 6 Ounce (Pack of 1)
I have been using Hawaiian Tropic sunscreen for years and absolutely love the smell. I wanted to try a spray version as I hate the feeling of oily hands after applying sunscreen. This version sprays on super evenly and has that same beachy smell as the lotion! It stays on for hours and doesn’t leave a sticky residue. My go to sunscreen! With such high SPF as well, this sunscreen truly cannot be best for the value.
