BAM XL | Acoustic Insulation Kit
Professional-Grade Acoustic Insulation for Uncompromising Sound
The Focal BAM XL Acoustic Insulation Kit is engineered to deliver the ultimate noise and vibration control for high-performance car audio systems. Designed using the same acoustic principles found inside Focal’s studio loudspeakers, BAM XL transforms your vehicle’s interior into a quieter, more immersive listening environment.
By combining a honeycombed damping layer, an aluminum constraint sheet, and a self-adhesive butyl viscoelastic complex, this tri-layer material effectively absorbs structural vibrations, reduces panel resonance, and eliminates intrusive road noise. The result? Tighter bass, cleaner mids, and greater overall sound precision.
Technology Highlights
Honeycombed Damping Material
Inspired by the internal acoustic foam of professional loudspeakers, this layer absorbs the rear sound wave from your speakers, preventing unwanted reflections and resonance. It enhances midbass clarity and optimises your speaker performance.
Aluminum Sheet
The rigid aluminum layer is key to the “sandwich effect.” It reinforces the structure of the viscoelastic layer, dramatically increasing damping efficiency and rigidity while maintaining a lightweight profile.
Viscoelastic Butyl Complex
This dense, self-adhesive butyl layer bonds directly to vehicle panels to absorb surface vibrations and block external noise. With exceptional acoustic sealing properties, it ensures quieter cabins and greater listening comfort.
Engineered for True Audio Enthusiasts
Perfect for installation on doors, floors, roofs, wheel arches, and firewalls, the BAM XL kit allows your Focal system to perform at its full potential. Less vibration means more music — every note delivered with impact and purity.
