HELIX Ci3 W165FM-S2

HELIX COMPOSE. The perfect speaker for any composition.

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. Innovative materials and the latest technologies paired with smart, practical engineering - the best of both worlds in harmony: high efficiency, fantastic sound quality and enormous dynamics that fit in any vehicle. HELIX COMPOSE - universal speakers evolved.

Price-performance highlight

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. As you already know from our i7 series, our new mechanical technologies with unbeatable practical benefits, are implemented here as well. All speaker impedances are perfectly matched for the combination with our HELIX and MATCH amplifiers, guaranteeing maximum performance at any time.

High efficiency

HELIX COMPOSE equals smart engineering and accordingly implements highly efficient 3 Ohm technology, that perfectly harmonizes with all HELIX and MATCH amplifiers and at the same time allows a clearly perceptible plus in efficiency and maximum sound pressure. Certain models will also be available as an optional 2 Ohm variants, assuring the absolute maximum performance and power of the respective speaker in combination with the appropriate amplifier.

Cenosphere paper cone

With the innovative "Cenosphere" coating, hollow spheres are incorporated into a polyamide layer that is applied to the cone. This process increases the stiffness and also optimizes its internal damping. The result is an exceptionally stable yet lightweight cone that offers outstanding precision in sound reproduction.

High-tech polymer basket

All HELIX COMPOSE i7 and i3 speaker baskets are made of a high-tech polymer composite, which has been additionally reinforced with glass spheres. The result: maximum stability with minimal self-resonance, while also eliminating flux modulation of the magnetic system and maximum resistance to thermal influences. Last but not least, this allows for much more compact basket dimensions and thus simplified installations in cramped installation conditions.

FlexMount165 – Universal meets car-specific

FlexMount is a mounting system based on specially developed adaptor rings, allowing the installation of COMPOSE FlexMount speakers in an almost infinite number of vehicles. Thus, the universal loudspeaker effortlessly becomes a vehicle-specific loudspeaker, that can be easily installed in the original installation position of the vehicle in an acoustically optimized way with the matching FlexMount adaptor ring.

ProConnect – The new industry standard

Our innovative ProConnect terminal is the new industry standard: A professional, automotive connector, allowing the safe use of conventional speaker cables, while also being ideally designed for connection via flat plug with our WireKits, offering maximum flexibility in the design of the sound system upgrade. Furthermore, the connection is interlocked, offers reverse polarity protection and is electrically and mechanically highly stressable.

WireKits – Plug & Play at its best

Our WireKits realize the connection of HELIX COMPOSE components to the original wiring harness, or optionally to the crossover, in the most comfortable way. With manufacturing according to the high standards of the automotive industry, these arrestable adaptor cables meet all requirements for the harsh environmental conditions that installers are facing in vehicles every day.

FAQs
Q: Will these speakers fit my car?

A: Most car speakers are standard sizes, but mounting depth and fitting rings vary by vehicle. Check the size in the Specification tab against your vehicle, or contact CEN with your registration and we will confirm fitment and any adapters or fitting kits you need.

Q: Do I need an amplifier to run these speakers?

A: Not always. Most speakers will run from a standard head unit, but a dedicated amplifier lets them perform at their best, particularly for component sets and higher power handling models. The RMS figure in the Specification tab is the guide to how much clean power they can use.

Q: What is the difference between coaxial and component speakers?

A: Coaxial speakers combine the tweeter and woofer in one unit for a simple like-for-like upgrade. Component sets separate the tweeter and woofer with a crossover for better imaging and detail, and suit installs where sound quality is the priority.

Q: Do these come as a pair?

A: Unless stated otherwise, car speakers are sold in pairs. Check the product title and What's Included tab, which lists exactly what is in the box.

Q: Can CEN fit these speakers for me?

A: Yes. CEN offers professional installation from our Nottingham premises. Contact us to book an installation slot or ask for a fitting quote.
