Helix Compose i5 Ci5 W165FM-S3 6.5" Midbass 3Ω

The HELIX COMPOSE i5 series guarantees an excellent sound experience in your vehicle. The i5 series is inspired by both the i3 and i7 series speakers, making it unbeatable in terms of price-performance ratio!

The impedance of the Compose series speakers has been optimized with Helix / Match DSP processors in mind.

Only high-quality materials are used in the Compose i5 series:

- The cones are silicone-coated paper cones, which achieve a very light structure, allowing for precise and expansive mid-range reproduction in the i5 series.

- The i5 series mid-range speaker features a metal phase plug, which reduces the compression effect and improves voice coil cooling.

- The baskets are made of polymer composite, further reinforced with glass beads, resulting in a very stiff and resonance-free material.

- Very powerful magnets

One of the key elements of the Compose series is the patented mounting system called FlexMount, which is based on specially developed speaker adapters.
This technology allows you to install i 7 speakers in an almost infinite number of car models by simply changing the adapter ring to one that fits your car.
The speaker is attached/detached from the adapter ring by twisting, which releases the protrusions on the element from the adapter.

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

The i5 series is compatible with all FlexMount, FlexConnect, ProConnect, and WireKits adapters.
