The HELIX Ci5 S200FM-S2 is a 200 mm hybrid mid-woofer and subwoofer from the COMPOSE series designed to combine universal speaker flexibility with vehicle-specific integration. It uses a lightweight polypropylene cone, a high-tech polymer composite basket reinforced with glass spheres, and a powerful magnet system to deliver high efficiency, low distortion and controlled low-frequency output.

Built for tight installation spaces, the Ci5 S200FM features a 47 mm mounting depth, FlexMount200 adapter compatibility, and available S2 or D2 voice coil configurations for 1 x 2 Ohms or 2 x 2 Ohms setups. The speaker covers a frequency range of 25 to 500 Hz and offers high linear excursion for under-seat and bulkhead installations in many vehicles while matching impedance behavior with HELIX and MATCH amplifiers.
