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.

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

- The body of the midbass is made of polymer composite, which is further reinforced with glass beads, resulting in a very rigid and non-tracking material.

- High-performance magnets.

- Separate high-quality split filter with 6-step treble 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 adapter ring for your car.

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

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

Note! 8″ models are supplied with protective brackets.
