Helix Ci3 W165FM-S2 speakers

Mid-Bass Speakers Helix Ci3 W165FM-S2

Born from the ever-increasing demands of modern in-vehicle technologies and HELIX’s typical drive for intelligent solutions. The company set out to progressively rework proven universal speaker systems. The result is the innovative HELIX COMPOSE platform, which, in line with the motto “developed inside the vehicle, for the vehicle,” combines classic universal speakers with the advantages of vehicle-specific systems. Innovative materials and the latest technologies together with smart and practical engineering deliver the best of both worlds in harmony: high efficiency, fantastic sound quality and enormous dynamics that fit into any vehicle. HELIX COMPOSE — universal speakers that have undergone a fundamental evolution.

Price/Performance Ratio

The HELIX COMPOSE i3 series represents the absolute peak in price/performance, and thanks to high-quality components and smart technical design provides a first-class audio experience. As you already know from the i7 series, new mechanical technologies with unrivaled practical benefits are implemented here as well. All speaker impedances are perfectly matched for use with HELIX and MATCH amplifiers, ensuring maximum performance under all conditions.

High Efficiency

HELIX COMPOSE stands for clever engineering — which is why it uses highly efficient 3-ohm technology that pairs perfectly with all HELIX and MATCH amplifiers. The result is a noticeable increase in efficiency and maximum acoustic output. Some models will also be available as optional 2-ohm variants to deliver absolutely maximum power and force from the respective speaker when combined with a suitable amplifier.

Cenosphere Paper Cone

Thanks to the innovative "Cenosphere" surface treatment, hollow spheres are incorporated into the polyamide layer applied to the cone. This process increases stiffness and optimizes internal damping. The result is an exceptionally stable yet lightweight cone that offers outstanding accuracy in sound reproduction.

High-Tech Polymer Basket

All baskets of the HELIX COMPOSE i7 and i3 speakers are made from a high-tech polymer composite that is further reinforced with glass beads. The result: maximum stability with minimal self-resonance, elimination of magnetic flux modulation, and maximum resistance to thermal effects. Last but not least, this allows much more compact basket dimensions, simplifying installation in confined fitment conditions.

FlexMount165 – Universal and Vehicle-Specific

FlexMount is a mounting system based on specially developed adapter rings that enables the installation of COMPOSE FlexMount speakers into an almost unlimited number of vehicles. A universal speaker thus becomes, without effort, a vehicle-specific speaker that can be easily installed into the vehicle’s original mounting position using the appropriate FlexMount adapter ring in an acoustically optimized way.

ProConnect – A New Industry Standard

The brand’s innovative ProConnect terminal is a new industry standard: a professional connector for the automotive industry that allows secure use of standard speaker cables while being ideally designed for connection via flat connectors with Helix cable kits, offering maximum flexibility when planning an upgrade. In addition, the connection is lockable, provides reverse-polarity protection, and is engineered for high electrical and mechanical load.

WireKits — Best Plug & Play Solution

Our WireKits provide the most convenient way to connect HELIX COMPOSE components to the factory wiring harness or, optionally, to a crossover. Manufactured to high automotive standards, these lockable adapter cables meet all requirements for the harsh environmental conditions installers encounter in vehicles every day.
