HELIX Ci5 M80FM-D3 CTR

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.

The Sound Sensation for sophisticated music lovers 

The HELIX COMPOSE i5 series is the link between i7 and i3, created for sophisticated music lovers with a sparked ambition for a true hi-fi experience. A lovechild of phenomenal sound and unmatched practicality: Developed with the vision of unique speaker highlights that are also true problem solvers. All speaker impedances are perfectly matched for the combination with our HELIX and MATCH amplifiers, guaranteeing maximum performance at any time. In addition, we implemented our COMPOSE-exclusive mechanical technologies that offer unbeatable practical benefits. 

Precise broadband performance for demanding center-channel applications

The Ci5 M80FM-D3 CTR has been engineered as an audiophile broadband driver for center-channel applications in high-quality multi-way systems. Its wide linear frequency range, high power handling and generous linear excursion enable exceptionally clear, natural and dynamic sound and speech reproduction – even at high listening levels.
A key feature of the Ci5 M80FM-D3 CTR is its separate voice coil for supporting the vehicle’s automatic emergency call function. While one voice coil carries the music signal, the second provides a separate connection for the factory eCall system. This allows the original center speaker to be replaced with a high-quality audio solution without compromising this essential vehicle function. 
Thanks to its significantly reduced outer diameter compared with conventional 3 inch / 80 mm drivers, the Ci5 M80FM-D3 CTR also offers outstanding integration flexibility – for example in tight factory mounting locations using FlexMount technology, without compromising the cone area. This makes it perfectly suited for demanding multi-way systems, DSP-optimized setups or vehicles where precise sound reproduction and a compact form factor are equally important. In line with its intended use as a center speaker, the Ci5 M80FM-D3 CTR is supplied as a single loudspeaker.

Sophisticated engineering for dynamics, efficiency and low distortion

The remarkable performance of the Ci5 M80FM-D3 CTR is the result of a carefully coordinated combination of materials and mechanical design. Its silicon-coated paper cone provides high internal damping, an exceptionally natural and accurate sound reproduction and suppresses unwanted resonance frequencies. The particularly narrow surround structure, whose inward-folded surround edge is bonded in a complex manufacturing process, works in conjunction with the innovative magnet system to allow for a large linear excursion – a key factor behind the driver’s high power handling and low-distortion behavior, ensuring confident performance even at elevated listening levels. 
Furthermore, it noticeably reduces the outer diameter while increasing the effective cone area. The result is a compact form factor paired with high acoustic efficiency. Completing the design is an aluminum dustcap that enhances upper-midrange performance, along with a powerful push-pull neodymium magnet system that combines high efficiency with minimal distortion – contributing significantly to the precise, dynamic sonic character of the Ci5 M80FM-D3 CTR. 

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.

High-tech polymer basket

The Ci5 M80FM-D3 CTR speaker basket is 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.

FlexMount80 – 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. 
For even greater installation flexibility, the Ci5 M80FM-D3 CTR scope of delivery also includes the CFMK80-100 adaptor ring. The speaker is mounted directly into this adaptor, enabling it to be combined with separately available FlexMount100 adaptors for installation in vehicle-specific 4 inch / 100 mm mounting positions.

FlexConnect – One terminal for all cases

With our FlexConnect terminal, HELIX COMPOSE speakers can easily be connected directly to the original wiring harness of the vehicle, maintaining the automotive standard of the plug connection as well as guaranteeing reverse polarity protection. Similar to our FlexMount system, this technology relies on specially developed, vehicle-specific adaptors.

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.
