Description
HELIX Compose CFMK165 MB.7
The CFMK165 MB.7 is a Helix Compose FlexMount165 adaptor ring set. It turns a universal 6.5″ / 165 mm Helix Compose midbass with FlexMount165 technology into a vehicle-specific speaker, so it fits the car’s original midbass location, acoustically optimised.
Audiotec Fischer lists it as: suitable for the rear mounting locations in Mercedes Benz W447 with factory installed woofer. Fitment varies by model and year, so check your car with us (or on Helix’s FlexMount Finder) before ordering.
The rings are 3D printed (FDM) in Germany by Audiotec Fischer from an automotive-grade material that is very strong and rigid, resistant to weather, UV, oils and grease, and stable from -40 °C to over +90 °C.
