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.\u003c\/p\u003e\n\u003ch4\u003eThe Sound Sensation for sophisticated music lovers \u003c\/h4\u003e\n\u003cp\u003eThe 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. \u003c\/p\u003e\n\u003ch4\u003eHigh efficiency\u003c\/h4\u003e\n\u003cp\u003eHELIX 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.\u003c\/p\u003e\n\u003ch4\u003eVersatility at its finest\u003c\/h4\u003e\n\u003cp\u003eThe Ci5 W165FM-S3 midbass is a true all-rounder within the COMPOSE platform. With its finely tuned acoustic design, it effortlessly adapts to both classic two-way setups and more complex three-way configurations. A key element of this versatility is the precisely engineered phase plug, which not only reduces mechanical compression and supports more even sound dispersion, but also significantly enhances the impulse response in the upper midrange. Matched in color to the dome of the Ci5 T25FM-CA tweeter, it creates a visually cohesive pairing – ideal for systems where sonic excellence and aesthetic harmony go hand in hand. The lightweight yet exceptionally rigid paper cone features a premium silicon coating, allowing for an impressively low resonance frequency while extending the upper midrange performance. The result is a loudspeaker that excels in every discipline – with precision, dynamics, and a clear focus on musical expression. \u003c\/p\u003e\n\u003ch4\u003eHigh-tech polymer basket\u003c\/h4\u003e\n\u003cp\u003eAll HELIX COMPOSE i7 and i3 speaker baskets are 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.\u003c\/p\u003e\n\u003ch4\u003eFlexMount165 – Universal meets car-specific\u003c\/h4\u003e\n\u003cp\u003eFlexMount 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.\u003c\/p\u003e\n\u003ch4\u003eProConnect – The new industry standard\u003c\/h4\u003e\n\u003cp\u003eOur innovative ProConnect terminal is the new industry standard: A professional, automotive connector that provides a safe connection to our WireKits, but also allows the use of conventional speaker cables or car-specific adaptor cables via flat plugs, giving maximum flexibility in the design of the sound system upgrade.
