Helix Compose Ci3 K165.2FM-S3 – 6.5″ 3 Ohm Component Set

HELIX COMPOSE. The perfect speaker for any composition.

HELIX COMPOSE series is developed to meet the growing demands of modern automobile audio systems. It combines advanced materials and engineering for high efficiency, accurate sound reproduction, and reliable integration in various vehicles.

Performance highlight

The i3 component systems deliver clear and detailed sound using high-quality materials and practical engineering. All components work together efficiently with HELIX and MATCH amplifiers for consistent output and reliable performance. The system is designed for safe connection, easy installation, and broad compatibility in vehicles.

High efficiency

This series uses a highly efficient 3-Ohm design that pairs well with HELIX and MATCH amplifiers, improving overall sound pressure and performance. Some versions are also available in 2-Ohm variants for optimized power handling.

Cenosphere paper cone

The “Cenosphere” coating integrates hollow spheres within a polyamide layer on the cone. This increases stiffness and improves internal damping, creating a stable yet lightweight cone with precise sound reproduction.

High-tech polymer basket

All HELIX COMPOSE i7 and i3 speaker baskets are made from a reinforced polymer composite with glass spheres. This ensures high stability, minimal resonance, and resistance to temperature changes while allowing compact dimensions for easier installation in tight spaces.

Stunning highs and stability

The 0.75” / 20 mm tweeter features a titanium dome that offers high rigidity, low moving mass, and good internal damping. It delivers clean, detailed high frequencies without distortion.

Perfectly separated

The Ci3 FX-UNI.2 crossover is made for HELIX COMPOSE i3 components, offering a 6-stage tweeter level adjustment with a 12 dB slope and integrated protection. It ensures balanced frequency distribution and can be installed easily due to its compact size. It also supports COMPOSE Connect and WireKit systems for safe and accurate installation.

COMPOSE Connect

This connection system uses plug-in connectors that simplify installation and ensure a secure, polarity-safe connection meeting automotive standards.

FlexMount20 & FlexMount165 – Universal meets car-specific

The FlexMount system allows these speakers to be installed in a wide range of vehicles using specially designed adapter rings. This setup makes it possible to fit the speakers into original factory positions for optimized acoustic results.

WireKits – Plug & Play integration

WireKits provide easy connection of HELIX COMPOSE speakers to the original wiring harness. Built to automotive standards, these adapters are durable and designed for vehicle conditions.
