Helix Ci5 S200FM-D2 - 20cm speaker

Helix Ci5 S200FM-D2 - 20cm loudspeaker

HELIX COMPOSE. The perfect loudspeaker for every composition.

Arose from 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 motto "developed in the car, for the car".
Innovative materials and the latest technologies paired with smart, practical engineering - the best of two worlds in harmony: very high efficiency, fantastic sound quality and enormous dynamics that fit into every vehicle.
HELIX COMPOSE - universal loudspeakers taken further.

The sound sensation for demanding music lovers

The HELIX COMPOSE i5 series is the link between i7 and i3, created for demanding music lovers with a keen ambition for a real HiFi 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 the combination with our HELIX and MATCH amplifiers, which guarantees maximum performance and power output at all times.
In addition, we have implemented our COMPOSE-exclusive mechanical technologies, which offer unrivalled practical benefits.

Woofer and subwoofer in one - the best of both worlds

The Ci5 S200FM is a 200 mm hybrid loudspeaker that is the perfect balance between a woofer and subwoofer and impresses across the board thanks to its exceptionally long stroke, high load capacity and volume.
With its linear excursion of +/- 7.8 mm (D2: +/- 7.5 mm), controlled and clear bass reproduction is always ensured - even at high levels and low frequencies.
The aim was to develop a loudspeaker that works perfectly in BMW under-seat and Mercedes bulkhead applications without any compromises, despite the extremely low installation depth of 47 mm.
The FlexMount200 technology makes the Ci5 S200FM easy and problem-free to integrate and, thanks to its design, opens up completely new integration options.

High-tech polymer composite basket

All HELIX COMPOSE i7, i5 and i3 loudspeaker baskets are made from a high-tech polymer composite material that has been additionally reinforced with glass beads.
The result: maximum stability with minimal natural resonance, which also eliminates flow modulation of the magnet system and also provides maximum resistance to thermal influences.
Finally, this enables much more compact basket dimensions and thus simplified installation in cramped installation conditions.

Flexible connection - 2 x 2 or 1 x 2 Ohm

The chassis are available as either a 1 x 2 Ohm (S2) or 2 x 2 Ohm (D2) variant. This means that for every conceivable amplifier configuration - whether monoblock, two-channel power amplifier or multi-channel amplifier - there is always the right woofer to get the maximum performance out of it.

FlexMount200 - universal meets vehicle-specific

FlexMount is a mounting system based on specially developed adapter rings, which enables the installation of COMPOSE FlexMount loudspeakers in an almost infinite number of vehicles.
This turns the universal loudspeaker into a vehicle-specific loudspeaker in no time at all, which can be installed easily and acoustically optimized in the original installation position of any vehicle with the appropriate FlexMount ring.

Features

• Exceptionally high excursion - enables high sound pressure and impressive bass reproduction
• Hybrid flat woofer concept - perfect balance between a powerful subwoofer and a woofer that covers a frequency range from 25 to 500 Hz
• Flexible connection - chassis with 2 x 2 ohm double voice coil enables every conceivable amplifier configuration to get the maximum performance
• Minimal installation depth - innovative basket design with only 47 mm installation depth allows use in tight installation spaces
• Compact dimensions with maximum performance - despite the small outer diameter, the Ci5 S200FM has the same membrane surface as a typical 200 mm chassis
• Lightweight and at the same time extremely rigid polypropylene membrane for phenomenal sound performance
• High-tech polymer composite basket reinforced with glass beads for maximum rigidity and minimal resonance
• Powerful magnet system for high efficiency and optimal impulse behavior
• Perfect for complicated applications - can be installed under the seats in many BMW models or as a front subwoofer in Mercedes vehicles, for example
• FlexMount200 technology - Compatible with the optionally available, vehicle-specific adapter rings, which enables acoustically optimized and professional integration in the original installation positions of under-seat and bulkhead speakers
