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.
