Helix Ci3 W165FM-S3 speakers

Helix Ci3 W165FM-S3 Mid-Bass Speakers

Born from the ever-increasing demands of modern 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—true to the motto "developed inside the vehicle, for the vehicle"—combines classic universal loudspeakers with the advantages of vehicle-specific systems. Innovative materials and the latest technologies, paired with smart and practical engineering solutions: the best of both worlds in harmony—high efficiency, fantastic sound quality and enormous dynamics that suit any vehicle. HELIX COMPOSE—universal speakers that have undergone a fundamental evolution.

Value for money

The HELIX COMPOSE i3 line delivers outstanding value for money: thanks to high-quality components and clever engineering, it provides a premium sonic experience. As already demonstrated in the i7 range, new mechanical technologies with unmatched practical benefits are implemented here as well. All speaker impedances are perfectly matched for combination with HELIX and MATCH amplifiers, ensuring maximum performance in every situation.

High efficiency

HELIX COMPOSE stands for clever engineering—therefore it uses a highly efficient 3-ohm design 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 drive from the speaker when combined with a suitable amplifier.

Cenosphere paper cone

Thanks to the innovative "Cenosphere" surface treatment, hollow glass microspheres are incorporated into the polyamide layer applied to the cone. This process increases stiffness while optimizing 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 additionally reinforced with glass beads. The outcome: maximum stability with minimal intrinsic resonance, elimination of magnetic system flux modulation and maximum resistance to thermal effects. Last but not least, this allows for much more compact basket dimensions and simplifies installation in tight mounting conditions.

FlexMount165 - universal and vehicle-specific

FlexMount is a mounting system based on specially developed adapter rings that allows COMPOSE FlexMount speakers to be installed in an almost unlimited number of vehicles. A universal speaker can thus effortlessly become a vehicle-specific unit that can be acoustically optimized and easily installed into the vehicle’s original mounting position using the appropriate FlexMount adapter ring.

ProConnect - a new industry standard

The innovative ProConnect terminal is a new industry standard: a professional automotive connector that allows safe use of standard speaker cables and is ideally designed for connection via flat connectors with this brand’s cable kits, offering maximum flexibility in sound system upgrades. In addition, the connection is locked, provides reverse-polarity protection and is highly stressed both electrically and mechanically.

WireKit sets - the best Plug & Play solution

WireKit sets provide the most convenient way to connect HELIX COMPOSE components to the vehicle’s factory wiring harness or, optionally, to a crossover. Manufactured to high automotive industry standards, these lockable adapter cables meet all requirements for the harsh environmental conditions encountered by installation professionals every day.
