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.

Natural brilliance and precise detail resolution

The new Ci3 tweeter features an elegant black aluminum dome that strikes the perfect balance between low weight and high rigidity. Combined with the refined, highly efficient neodymium magnet system, it delivers an even more precise, clear, and detailed high-frequency response. The result is natural brilliance with outstanding resolution and impressive dynamics – for an exceptional listening experience.

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.

Great daily sunscreen with lightweight feel
Size: 1.7 Fl Oz (Pack of 1), Size: 1.7 Fl Oz (Pack of 1)
I’ve been using this sunscreen daily and I really like it. It feels very light on the skin, absorbs quickly, and does not leave a greasy or heavy feeling. It also works well under makeup and does not cause breakouts. I feel my skin is well protected from the sun and it’s gentle enough for everyday use. I highly recommend it for anyone looking for a reliable sunscreen.

Great for oily acne-prone skin
Size: 3 Fl Oz (Pack of 1)
I have oily, acne-prone skin, and this sunscreen has worked really well for me. It doesn’t feel overly greasy or too dry, and it sits nicely on my skin without making my face feel heavy. I’ve been using it for a long time, and honestly, it’s the only sunscreen I keep going back to because it works so well with my skin. It feels comfortable for daily use and gives good protection without causing extra breakouts for me.

Great for oily skin!
Size: 3 Fl Oz (Pack of 1)
Definitely leaves white cast, I’m pretty fair skinned, makes me look like a ghost. Just rub it in your hands first, breaks into the mineral so minimize the white cast look. It feels lightweight and as someone with pretty oily skin it does a pretty good job!

Great for Oily, Rash-Prone Skin, But Be Wary of the Residue
Size: 1.7 Fl Oz (Pack of 1)
This sunscreen is a really solid option if you have sensitive, rash-prone, and oily skin like mine. I’ve found it’s one of the few sunscreens that doesn't cause any irritation, which is a huge benefit for me. On top of that, it leaves a truly matte finish, so I don't feel greasy or shiny throughout the day. The only reason I can't give it five stars is that it leaves behind small, dried white bits on my face. They can be a bit annoying and make the application look a little messy. Overall, it's a good sunscreen that works well with my skin type, but the white residue is a definite drawback.

This stuff is magic!
Size: 1.7 Fl Oz (Pack of 1)
I farm and garden. I spend hours outdoors in the summer, and for years, I’ve hated wearing sunscreen because it made my face feel hot and sticky. This sunscreen is none of that. I received a small sample tube of it from the dermatologist and instantly fell in love with it. It goes on smooth and covers well. But the thing I love about it is that I don’t feel like I’m wearing sunscreen once it absorbs into my skin. I forget about it! It doesn’t combine with my sweat and run into my eyes, making them sting. It doesn’t irritate sensitive skin or clog my pores. This stuff is magic and I will be using it daily. It’s not the least expensive sunscreen out there, but it’s worth it!
