FlexMount is our patented mounting system, based on specially developed adaptor rings.
With just one turn, your universal 4" / 100 mm HELIX COMPOSE midrange speaker with FlexMount100 technology becomes car-specific, allowing an easy and acoustically optimized installation in the original mounting position of the vehicle.
