Helix Ci3 W165FM-S2 - 2 Ohm
The HELIX COMPOSE i3 series is a top quality midbass with an excellent price/quality ratio
Compose i3 series uses high-quality materials:
- Extremely lightweight and coated paper cone ensures accurate and detailed reproduction.
- The frame is made of a polymer composite, which is additionally reinforced with glass beads, resulting in a very rigid and reverberant-free material.
- Powerful magnet
One of the key elements of the Compose series is a patented mounting system called FlexMount, which is based on specially developed speaker adapters.<br>
This technology allows you to install i3 speakers in an almost infinite number of car models by simply changing the adapter ring that fits your car.
FlexMount adapter rings are either included with the speaker or can be purchased separately (be sure to check out our FlexMount selection).
The i3 series is compatible with all FlexMount, FlexConnect, ProConnect and WireKits adapters.
