Description
HELIX Compose CFMK25 AUD.3
The CFMK25 AUD.3 is a Helix Compose FlexMount25 adaptor ring set. It turns a universal 1″ / 25 mm or 0.75″ / 20 mm Helix Compose tweeter with FlexMount25 technology into a vehicle-specific speaker, so it fits the car’s original tweeter location, acoustically optimised.
Audiotec Fischer lists it as: suitable for various Audi vehicles with factory installed tweeter. Fitment varies by model and year, so check your car with us (or on Helix’s FlexMount Finder) before ordering.
Its two-part design takes either a 1″ / 25 mm or a 0.75″ / 20 mm Helix Compose tweeter.
