Boom Mat Speaker Baffles reduce speaker-induced rattles and vibrations, protect the rear of the speaker from damage, and help keep moisture out of the mounting area.
Made from closed-cell polyethylene, these baffles isolate frequency responses while damping sheet metal and panel-to-frame resonance. They also help prevent sound from migrating into unfavorable areas of the vehicle (such as door panels) and conform easily in tight spaces for a clean installation.
- Maximizes speaker performance by isolating frequency responses
- Dampens vibrations and reverberation
- Forms a water-tight protective shell to help prevent moisture intrusion
