Compose Series speakers are optimized for Helix/Match DSP processors.

The Compose i3 series are made of high quality materials:

- Titanium calotte tweeter with excellent sound quality.

- The midbass has a very lightweight, coated paper cone for accurate and detailed reproduction.

- The body of the midbass is made of a polymer composite, reinforced with glass beads to obtain 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 changing the fitting ring to suit your car.

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