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

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

The Compose i3 series uses high quality materials:

- Titanium calotte tweeter with excellent sound quality.

- Extremely lightweight and coated paper cone of the midbass ensures accurate and detailed reproduction.

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

- High-performance magnets.

- Separate high-quality split filter with 6-step tweeter level control.


- 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 swapping in the appropriate adaptor ring for your car.

FlexMount adaptor rings are either included with the speaker or sold separately ( be sure to check out our FlexMount range ).

i3 Series is compatible with all FlexMount, FlexConnect, ProConnect and WireKits adaptors.
