The HELIX COMPOSE i7 series represents uncompromising excellence, ensuring a superior audio experience in your vehicle. With the obvious influence of its high-end sister brand BRAXI, the i7 speaker series is manufactured entirely in Germany and optimised for uncompromising sound quality.

The ohmic rating of the Compose series speakers is optimised for Helix/Match DSP processors.

The Compose i7 series use only the highest quality materials:

- The cones are UHD ( ultra high damping crafter paper cone ) paper cones

- The cones are made of polymer composite, additionally reinforced with glass beads to obtain a very rigid and non-tracking material.

- High-performance magnets

One of the key elements of the Compose series is a patented mounting system called FlexMount, based on specially developed speaker adapters.
This technology allows you to mount i 7 speakers on an almost infinite number of car models by simply changing the fitting ring that fits your car.
The speaker is attached/detached from the adapter ring by rotating the ring, allowing the lugs on the element to disengage from the adapter.

FlexMount adapter rings are either supplied with the speaker or can be purchased separately ( be sure to check out our FlexMount range ).

i7 series is compatible with all FlexMount, FlexConnect, ProConnect and WireKits adapters.
