The HELIX COMPOSE i3 series is a top-quality midrange with an excellent price/quality ratio.
The Compose i3 series uses high quality materials:
- A very lightweight and coated paper cone ensures accurate and detailed reproduction
- The body is made of polymer composite, which is further reinforced with glass beads, resulting in a very rigid and non-tracking material.
- A low profile but highly efficient magnet.
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 i3 speakers on an almost infinite number of car models by simply changing the adapter ring that fits your car.
The speaker is attached/detached from the adapter ring by rotating it, which releases the lugs on the element from the adapter.
FlexMount adapter rings are either included with the speaker or can be purchased separately ( be sure to check out our FlexMount range ).
i3 series is compatible with all FlexMount, FlexConnect, ProConnect and WireKits adapters.
