HELIX COMPOSE CB K165.2-S3 is a 6.5 inch 2-way component speaker kit that pairs a lightweight polypropylene midbass with a 20 mm silk-dome tweeter and a compact passive crossover. The platform is engineered for in-vehicle use and emphasizes high efficiency via 3 Ohm technology to better match HELIX and MATCH amplifiers.

The midbass features a ventilated steel basket and a polyurethane dustcap for controlled midrange response while the tweeter uses a coated silk dome and a neodymium magnet for clear high-frequency reproduction. The crossover offers a 12 dB slope and a 4-stage tweeter level adjustment; FlexMount20 adaptor compatibility and included mounting pods support acoustically optimized, vehicle-specific integration.
