THREE MATERIALS, THREE FUNCTIONS
The B.A.M. consists of a honeycombed damping material that attenuates the rear wave of the loudspeaker and enhances its performance, an aluminium sheet to create a sandwich effect, and a self-adhesive butyl complex that absorbs vibrations from the surface with which it is in contact, and greatly attenuates external noise entering the car.
