HELIX Ci7 C165.2FM-S3

HELIX Ci7 C165.2FM-S3

Born out of the increasingly demanding challenges of modern vehicle technology and the HELIX-typical pursuit of intelligent solutions, we made the progressive redesign of proven universal loudspeaker systems our mission. The result: the innovative HELIX COMPOSE platform, which combines classic universal loudspeakers with the advantages of vehicle-specific systems according to the guiding principle "developed in the car, for the car".
Innovative materials and the latest technologies paired with smart, practical engineering - the best of both worlds in harmony: very high efficiency, fantastic sound quality and enormous dynamics that fit into any vehicle. HELIX COMPOSE - universal loudspeakers taken to the next level.

i7 - High-end car audio "Made in Germany"

The HELIX COMPOSE i7 series represents uncompromising high-end for an extravagant sound experience in the car. With a clear influence from the high-end sister brand BRAX, the i7 loudspeaker series is completely "Made in Germany" and optimized for unadulterated music enjoyment. The impedances of all speakers are perfectly matched to the combination with our HELIX and MATCH amplifiers, guaranteeing maximum performance and power output at all times. In addition, we have implemented new mechanical technologies in HELIX COMPOSE that offer unrivaled practical benefits.

Maximum efficiency
HELIX COMPOSE stands for smart engineering and is therefore based on the highly efficient 3 Ohm technology, which harmonizes perfectly with all HELIX and MATCH amplifiers and at the same time enables a clearly noticeable increase in efficiency and maximum sound pressure.

High-end coaxial coincident loudspeaker
The Ci7 C165.2FM-S3 is a unique coaxial loudspeaker that combines the best of the Ci7 W165FM-S3 high-end bass-midrange driver and Ci7 T20FM-SC high-end tweeter. Thanks to its sophisticated design, the Ci7 C165.2FM-S3 is not just a simple coaxial loudspeaker, but a true coincident transducer. This offers the advantage that the sound from both speakers is generated absolutely simultaneously, turning the speaker into a point source. This achieves extremely precise and time-coherent sound reproduction, which is particularly advantageous in acoustically demanding environments and logically complements the COMPOSE platform with another smart, practical solution.
With the i7-known UHD paper cone and the silk dome tweeter including integrated coupling volume damped with pure sheep's wool, the C165.2FM-S3 achieves an exceptional combination of powerful, precise low-midrange sound and brilliant, velvety-soft highs. The alignment of the drivers along the same axis of sound generation ensures optimum phase coherence and a consistent sound image. This makes the C165.2FM-S3 a versatile solution for audiophiles who want to experience a coherent soundstage from a single speaker position without sacrificing the intelligence and ease of integration of the COMPOSE platform.

High-tech polymer composite basket
All HELIX COMPOSE i7 and i3 speaker baskets are made from a high-tech polymer composite material, which is additionally reinforced with glass spheres. The result: maximum stability with minimum natural resonance, whereby flux modulation of the magnet system is also excluded and there is also maximum resistance to thermal influences. Finally, the cage dimensions are much more compact, which simplifies installation in confined spaces.

FlexMount165 - universal meets vehicle-specific
FlexMount is a mounting system based on specially developed adapter rings that allows COMPOSE FlexMount speakers to be installed in an almost infinite number of vehicles. In no time at all, the universal speaker is transformed into a vehicle-specific speaker, which can be installed easily and acoustically optimized in the original installation position of any vehicle using the matching FlexMount ring.

ProConnect - The new industry standard
Our innovative ProConnect terminal for the woofer reflects the new industry standard: this is a professional, automotive plug connection that is designed for a secure connection with our WireKits, but also allows the use of conventional speaker cables and vehicle-specific adapter cables via flat plugs and therefore offers maximum flexibility in the design of the sound system upgrade. In addition, the connection is interlocked, offers protection against reverse polarity and is electrically and mechanically highly resilient.

WireKits - plug & play at the highest level
Our WireKits make it easy to connect the HELIX COMPOSE loudspeaker system to the original wiring harness. Manufactured to the high standards of the automotive industry, these lockable adapter cables meet all the requirements for the harsh environmental conditions in vehicles.

Features
✓ 2-way high-end coaxial coincident loudspeaker, which combines unique sound characteristics with the most versatile integration possibilities
✓ Concentric speaker design as a true point source for outstanding sound dispersion and incomparable sound precision

Tweeter
✓ Extremely wide radiating 20 mm high-end silk dome tweeter with coupling volume for a particularly low resonance frequency
✓ Extremely light and fine-meshed silk dome tweeter for brilliant and soft high frequency reproduction
✓ Integrated, damped coupling volume enables a low crossover frequency thanks to the low resonance frequency
✓ 4 Ohm impedance

Bass-midrange driver
✓ 165 mm bass-midrange driver with UHD (Ultra High Damping) paper cone for excellent impulse fidelity and unsurpassed frequency response
✓ High-tech glass bead reinforced polymercomposite basket for highest rigidity and lowest resonances
✓ Large 37 mm voice coil for minimum thermal compression and high power handling
✓ High efficiency and 3 Ohm technology for maximized power output of the amplifier
✓ ProConnect connection terminal according to automotive standard allows the use of conventional speaker cables or a fast, connection with the optionally available WireKits
✓ Compatible with the optionally available, vehicle-specific FlexMount165 adapter rings, which enable acoustically optimized and professional integration in the original installation positions of the vehicle
✓ Compatible with the optionally available WireKits for a vehicle-specific, retrofittable connection to the original vehicle wiring harness
✓ Made in Germany


Important: The speaker does not have an integrated crossover. Two DSP amplifier channels per speaker are required for active operation. In addition, a high-pass filter for the tweeter must be set in the upstream DSP or DSP amplifier. Alternatively, the separately available Ci7 FX-UNI.2 crossover can be used.
