The HELIX COMPOSE i3 series is a top-quality midbass with an excellent price/quality ratio

The Compose i3 series uses the highest quality materials:

- Extremely lightweight and coated paper cone for accurate and detailed reproduction.

- The body is made of a polymer composite, further reinforced with glass beads for a highly rigid and non-traceable material.

- A powerful 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 fitting ring that fits your car.

FlexMount fitting 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.
