The HELIX Ci5 S200FM is an 8″ hybrid woofer (midbass/subwoofer) with an extremely shallow installation depth of 47mm. The Ci5 S200FM is available in 2 x2 and 1 x 2 Ohm versions.
Compatible with HELIX COMPOSE CFMK200 adapters.
This woofer is also suitable as a BMW bench sub with the CFMK200 BMW.1S adapter.
NOTE! not directly suitable for BMW Top Hifi (Harman/Kardon, Logic7, HiFi System Professional DSP and other names) systems with equipment codes S688A/S677A/S752A. The reason is that these amplifiers cannot withstand a 2 ohm load like the HiFi package S676A and S674A amplifiers and the player alone can.
