Wiring Wizard & Port Calculator

Use our wiring assistant for easy speaker and subwoofer connections! The correct connection is important for your amplifier! Low-impedance operation can damage the amplifier! The datasheet shows you which connection each amplifier is designed for!

Our port calculator shows you the tuning characteristics of your enclosure! The net volume is always particularly important here; calculate the subwoofer’s actual resonant chamber volume beforehand to get the correct result. The net volume is calculated by subtracting all dead spaces and is crucial for enclosure design.

HELIX Ci5 S200FM-S2

HELIX COMPOSE. The perfect speaker for every composition.

Born 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 speaker systems our mission.
The result: the innovative HELIX COMPOSE platform, which combines classic universal speakers 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.

The sound sensation for discerning music lovers

The HELIX COMPOSE i5 series is the link between the i7 and i3, created for discerning music lovers with an unbridled ambition for a true hi-fi experience. A fusion of phenomenal sound and unsurpassed practicality: developed with the vision of unique speaker highlights that are also true problem solvers. The impedances of all speakers are perfectly matched to our HELIX and MATCH amplifiers, guaranteeing maximum performance and power output at all times. In addition, we have implemented our COMPOSE-exclusive mechanical technologies, which offer unrivaled practical benefits.

Woofer and subwoofer in one - the best of both worlds

As a 200 mm hybrid loudspeaker, the Ci5 S200FM is the perfect balancing act between a woofer and subwoofer and impresses across the board thanks to its exceptionally long excursion, high power handling 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 speaker that works perfectly in BMW under-seat and Mercedes dashboard applications without any compromises, despite the extremely low installation depth of 47 mm.
Thanks to the FlexMount200 technology, the Ci5 S200FM can be integrated simply and easily and its design opens up completely new integration possibilities.

High-tech polymer composite basket

All HELIX COMPOSE i7, i5 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 minimal 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.

Flexible connection - 2 x 2 or 1 x 2 ohms

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

FlexMount200 - 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 easily installed in the original installation position of any vehicle with the matching FlexMount ring in an acoustically optimized manner.

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, covering a frequency range from 25 to 500 Hz
✓ Chassis with 1 x 2 Ohm voice coil for maximum power output of the amplifier
✓ Minimal installation depth - innovative basket design with only 47 mm installation depth allows use in confined installation spaces
✓ Compact dimensions with maximum performance - despite its small outer diameter, the Ci5 S200FM has the same cone area as typical 200 mm drivers
✓ Lightweight yet extremely rigid polypropylene cone for phenomenal sound performance
✓ High-tech polymer composite basket reinforced with glass beads for the highestTech polymer composite basket reinforced with glass beads for maximum rigidity and minimum resonance
✓ Powerful magnet system for high efficiency and optimum impulse response
✓ 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 enable acoustically optimized and professional integration in the original installation positions of under-seat and bulkhead speakers.

Frequently asked questions about the HELIX Ci5 S200FM-S2/D2 subwoofer

How do I install the HELIX Ci5 S200FM-S2/D2 in my car?

The subwoofer utilises the innovative HELIX Compose technology with the included Flexmount200 adapter rings. These allow for installation both in original mounting locations and in custom-built enclosures – fitting is tool-free thanks to the interchangeable system.

What impedance options does the dual-voice-coil system offer?

The Ci5 S200FM’s dual voice coil system can be connected either as 1 x 2 ohms or 2 x 2 ohms. This flexibility allows for optimum adaptation to various amplifier configurations and power requirements.

How low can the 200 mm subwoofer go?

Thanks to its specially developed 13 mm linear excursion, the HELIX Compose i5 subwoofer delivers exceptionally deep bass frequencies. The precision voice coil design ensures distortion-free reproduction, even at high volumes.

Is the subwoofer suitable for continuous use?

With its robust steel basket construction and high-quality materials, the Ci5 S200FM can easily handle continuous loads of up to 200 watts RMS. The well-designed cooling system for the voice coil prevents thermal overload.

What’s included in the package?

As well as the two 200 mm subwoofers, you will also receive mounting screws for installation. These allow the subwoofers to be fitted in a variety of installation scenarios.

Can I combine several Ci5 S200FM subwoofers?

Yes, the HELIX Compose i5 series is designed for multiple installations. Thanks to its uniform impedance design, several subwoofers can be connected in parallel or in series without any problems.

How does the S200FM differ from typical 200 mm drivers?

Unlike standard chassis, the HELIX Compose subwoofer features patented interchangeable technology for flexible installation. The special i5 and i3 speaker baskets ensure universal compatibility.

What case sizes are recommended?

For optimum performance, HELIX recommends specific enclosure volumes depending on the application. The exact figures can be found in the technical data sheet – generally speaking, the subwoofer operates efficiently in both sealed and bass-reflex enclosures.
