DEI 2 Pack 4" Inch Round Speaker Baffles Slim Design Engineering Boom Mat 050311

DEI 2 Pack 4" Inch Round Speaker Baffles Slim Design Engineering Boom Mat 050311 Boom Mat speaker baffles maximize speaker performance by isolating the correct frequency responses while damping reverberation in the sheet metal and panel to frame resonance. Forming a watertight protective shell, they prevent any type of unwanted moisture intrusion. Closed-cell polyethylene enhances frequency response for improved sound clarity and easy conformability in tight spaces for a professional installation. They isolate frequency responses and prevent sound from migrating to unfavorable areas in vehicles such as door panels.
