Focal B.A.M. Acoustic Insulation Kit Two 8-1/4" x 11-13/16" sheets

Insulate your car for better sound

Focal's B.A.M. — butyl acoustic mousse (butyl acoustic foam in English) — will deaden your car doors' noisy reverberations, clear up the sound of your speakers, and soundproof your interior from road noise. Without needing to add any electronic components, B.A.M. will dramatically improve the quality of your system's sound, especially its bass response.

Sandwich construction

Each Focal B.A.M. sheet is a three-layer sandwich made with a honeycombed damping material that absorbs the speaker's out of phase back wave, an aluminum support layer supplying acoustic isolation, and a butyl foam "viscoelastic complex" that sticks to the door and absorbs vibrations. Warranty: 60 days.
