HELIX Ci5 T25FM-CA

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. 

Brilliant treble with excellent dispersion characteristics

Despite the larger diameter of 25 mm / 1”, the Ci5 T25FM-CA has an excellent wide dispersion and off-axis response, allowing the creation of an impressive sound image and soundstage – even in OEM installation spots. With its ceramic-coated aluminum dome, it features a balanced frequency response and excellent decay characteristics. As a result, high frequencies are reproduced even more clearly and realistically. The sturdy aluminum housing with integrated grille provides optimal protection for the delicate dome, while the high-efficiency neodymium magnet ensures a linear magnetic flow. In true COMPOSE fashion, the design’s integration-friendly approach stands out: with its compact dimensions and flexible mounting options, including various mounting pods supplied, this tweeter is perfectly equipped to meet diverse installation requirements.

FlexMount25 – 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 tweeter effortlessly becomes a vehicle-specific tweeter, that can be easily installed in the original installation position of the vehicle in an acoustically optimized way with the matching FlexMount25 adaptor ring.

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.

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. This series is the lovechild of phenomenal sound and unmatched practicality.

Our i5 speakers are nothing less than real highlights in their segments as well as true problem solvers: The 200 mm / 8” speaker is a fusion of a mid-woofer driver and subwoofer and comes with an extraordinary flat installation depth, allowing the creation of hi-fi concepts without the particular need of an additional subwoofer in the trunk. Another highlight is the 25 mm / 1” tweeter with an aluminum dome coated with ceramic and an outstanding high frequency reproduction. As you would expect, our i5 speakers come with compatibility to our COMPOSE-exclusive mechanical technologies: FlexMount, FlexConnect, ProConnect, COMPOSE Connect and the WireKits.

Despite the larger diameter of 25 mm / 1”, the Ci5 T25FM-CA has an excellent wide dispersion and off-axis response, allowing the creation of an impressive sound image and stage – even in OEM installation spots. With its ceramic-coated aluminum cone, it features a balanced frequency response and excellent decay characteristics. As a result, high frequencies are reproduced even more clearly and realistically.

This 200 mm / 8” hybrid loudspeaker called Ci5 S200FM is the perfect balancing act between a midwoofer driver and subwoofer and offers exceptionally high excursion, power handling and output volume. The FlexMount200 technology ensures that it can be installed under the seats (BMW) or as a front subwoofer (MB), making it the ideal problem solver and perfect for difficult applications.

The particularly shallow installation depth of only 47 mm brings completely new, comfortable integration possibilities to the table – thus saving time, space and money. And don’t underestimate its performance: The Ci5 S200FM offers +/- 7.8 mm linear excursion, assuring a controlled and clear sonic reproduction even at high sound pressure levels and low frequencies.
