HELIX COMPOSE Ci5 S200FM-D2 | 8" Hybrid Flat Subwoofer | COMPOSE i5 Series

Universal Speakers Evolved. COMPOSE Technology.

Experience the perfect balance between mid-woofer and subwoofer with HELIX COMPOSE Ci5 S200FM-D2's innovative hybrid design—featuring dual 2Ω voice coils, exceptional 7.5mm excursion, and ultra-shallow 47mm depth for under-seat and bulkhead applications.

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 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. The Ci5 S200FM-D2, as a 200mm hybrid speaker, strikes the perfect balance between a mid-woofer driver and a subwoofer, impressing with its exceptionally high excursion, power handling and output volume. With its linear excursion of ±7.5mm, it consistently delivers controlled and clear low-frequency reproduction, even at high sound pressure levels, while the ultra-shallow 47mm installation depth makes it perfect for BMW under-seat and Mercedes bulkhead applications.

COMPOSE Ci5 S200FM-D2 Features:

• Exceptional cone excursion – ensures high sound pressure levels and impressive low-frequency reproduction
• Hybrid flat woofer concept – a perfect balance between a powerful subwoofer and a mid-woofer driver that covers a frequency range from 25 to 500 Hz
• Flexible connection – chassis with 2 x 2 Ohms dual voice coil always offering the right solution for every amplifier configuration to achieve maximum performance
• Minimum installation depth – an innovative basket design with only 47 mm installation depth for the use in restricted mounting spaces
• Compact dimensions with maximum performance – despite the small outer diameter, this woofer comes with the same cone area known from typical 200 mm chassis
• Lightweight polypropylene cone which provides essential stiffness for phenomenal sound performance
• High-tech polymer composite basket reinforced with glass beads for enormous rigidity and minimized ringing
• Powerful magnet system for high efficiency and optimum impulse response
• Perfect for difficult applications – e.g. can be installed under the seats in various BMW models or as front subwoofer in Mercedes cars
• FlexMount200 technology – Designed car-specific adapters, which allow acoustically-optimized and professional integration in the original installation positions of under-seat and bulkhead loudspeakers
• Dual voice coil configuration for maximum amplifier compatibility
• Works perfectly without compromises in extremely restricted mounting spaces
• COMPOSE-exclusive mechanical technologies with practical benefits
• Perfect impedance matching for HELIX and MATCH amplifiers
