HELIX Ci5 M50FM-S3

HELIX COMPOSE. The perfect loudspeaker for every composition.

Born from the ever-increasing demands of modern vehicle technology and HELIX's signature pursuit of intelligent solutions, we made the advanced redesign of proven universal loudspeaker systems our mission.
The result: The innovative HELIX COMPOSE platform, which, following the principle "developed in the car, for the car," combines classic universal loudspeakers with the advantages of vehicle-specific systems. Innovative materials and cutting-edge 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 loudspeaker reimagined.

The sound sensation for discerning music lovers

The HELIX COMPOSE i5 series is the link between i7 and i3, created for discerning music lovers with a burning ambition for a true hi-fi experience. A fusion of phenomenal sound and unsurpassed practicality: Developed with the vision of unique loudspeaker highlights that are also true problem solvers. The impedances of all loudspeakers are perfectly matched to our HELIX and MATCH amplifiers, guaranteeing maximum performance and power output at all times. Furthermore, we have implemented our COMPOSE-exclusive mechanical technologies, which offer unparalleled practical benefits. Audiophile wideband performance with flexible integration options. The Ci5 M50FM-S3 expands the COMPOSE platform with a highly advanced 50 mm wideband loudspeaker that impresses with its exceptionally compact design: Thanks to its significantly reduced outer diameter compared to typical 50 mm loudspeakers, as well as FlexMount technology, the Ci5 M50FM-S3 can be easily installed even in tight OEM installation spaces. This makes it particularly suitable for installation positions where space constraints, unfavorable dispersion angles, or factory specifications make classic two- or three-way applications difficult.
Thanks to its exceptionally wide frequency range, it enables setups that don't require a separate tweeter. Its high power handling and clear, low-distortion high-frequency reproduction also make it the ideal solution for center channel applications, high-performance full-range systems, and DSP-based setups that demand outstanding sound quality in a minimal footprint.

Smart design for maximum efficiency, dynamics, and detail resolution

The exceptional performance of the Ci5 M50FM-S3 is based on a number of precisely tuned design features. The specially shaped rubber surround and the innovative magnet system allow for an unusually large linear diaphragm excursion for this size, ensuring impressive power handling and extremely low-distortion reproduction. This combination also forms the basis for an exceptionally smooth, wide-band frequency response for a 50 mm driver, without the typical peaks or dips found in many compact full-range loudspeakers. At the same time, the exceptionally large diaphragm area, combined with a significantly reduced outer diameter (compared to typical 50 mm loudspeakers), maximizes performance and gives the full-range driver remarkable dynamics. Another key to its detailed high-frequency reproduction is the aluminum dust cap directly connected to the voice coil. Its lightweight and rigid construction improves impulse response even at the highest frequencies, giving the Ci5 M50FM-S3 its exceptional transparency and resolution. The silicate-coated paper cone ensures high internal damping, a natural and precise sound signature, and suppresses unwanted resonances. The overall technical concept is complemented by the high-performance push-pull neodymium magnet system, which, thanks to efficient magnet guidance, both increases efficiency and reduces distortion to a minimum – the basis for clean, confident sound performance even at demanding volume levels.

Maximum Efficiency

HELIX COMPOSE stands for smart engineering and is therefore based on highly efficient 3-ohm technology, which harmonizes perfectly with all amplifiers and amplifiers and simultaneously enables a noticeably increased efficiency and maximum sound pressure level.

High-Tech Polymer Composite Basket

The The speaker basket of the Ci5 M50FM-S3 is made of a high-tech polymer composite material, which is further reinforced with glass beads. The result: maximum stability with minimal resonance, while also eliminating flux modulation of the magnet system and ensuring maximum resistance to thermal influences. Finally, this allows for significantly more compact basket dimensions and thus simplified installation in confined spaces. FlexMount50 – Universal meets vehicle-specific. FlexMount is a mounting system based on specially developed adapter rings, which enables the installation of COMPOSE FlexMount speakers in a virtually unlimited number of vehicles. This transforms the universal loudspeaker into a vehicle-specific loudspeaker in no time, allowing for easy and acoustically optimized installation in the original mounting position of any vehicle using the appropriate FlexMount ring.
