Helix Ci3 C165.2FM-S3 - 3Ohm
The HELIX COMPOSE i3 series is a top-quality 2-way coaxial with an excellent price/quality ratio.
The ohm rating of the Compose series speakers is optimized for the Helix / Match DSP processors.
Compose i3 series uses high-quality materials:
- Titanium dome tweeter with excellent sound quality.
- The midbass's extremely lightweight and coated paper cone ensures accurate and detailed reproduction.
- The midbass body is made of a polymer composite, which is additionally reinforced with glass beads, resulting in a very rigid and reverberant-free material.
- Powerful magnets.
- High-quality crossover with integrated 6dB high-pass filter
One of the key elements of the Compose series is a patented mounting system called FlexMount, which is based on specially developed speaker adapters.
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.
