HELIX COMPOSE Ci3 W165FM-S2 | 6.5" Performance Midbass Driver | COMPOSE i3 Series

Universal Speakers Evolved. COMPOSE Technology.

Experience maximum power output with HELIX COMPOSE Ci3 W165FM-S2's innovative design—featuring 2Ω technology, Cenosphere paper cone, FlexMount165 compatibility, and ProConnect terminal for superior midbass performance and vehicle-specific integration.

Born out of the increasingly demanding challenges of modern automobile technology and the HELIX-typical pursuit of intelligent solutions, we made the progressive redesign of proven universal speaker systems our mission. The result: our innovative HELIX COMPOSE platform that, according to the motto "developed inside the vehicle, for the vehicle", combines classic universal speakers with the advantages of vehicle-specific systems. Our HELIX COMPOSE i3 series is an absolute price-performance highlight, providing a first-class sound experience thanks to high-quality components and smart engineering. The Ci3 W165FM-S2 features innovative 2Ω technology for maximum power output and Cenosphere coating with hollow spheres incorporated into a polyamide layer, creating an exceptionally stable yet lightweight cone for outstanding precision in sound reproduction.
