Acoustic Abatement
ACUDAMP – Acoustic Treatment
At Morel, we’re fanatics about getting the best performance out of your audio system. Upgrading to our award-winning speakers is a tremendous first step, but making sure your listening environment is free of noise and vibration will allow your Morel speakers to perform to a much higher level. With this in mind, Morel developed ACUDAMP – a premium line of acoustic materials engineered to significantly reduce interior resonances and isolate and dampen noise to improve the acoustic properties of your vehicle. Applying ACUDAMP materials in key areas will significantly enhance bass performance and reduce distortion to ensure optimized performance of any sound system.
The MAT 221.10 is a 2.1 mm while 227.8 is a 2.7mm premium triple-layer damping and vibration control mat that conforms and fuses to sheet metal and other hard substrates and surfaces to eliminate unwanted resonances, improves the damping properties of the car and maximizes the potential of any sound system.
The MAT 345.5 is a premium quad-layer sheet composed of a special blend of materials, designed to dramatically improve any car audio system performance by minimizing road noise, reduce unwanted vibrations, improve the damping factor of the car’s cabin and offer heat insulation all in one single product.
The large sheet size of the Acudamp range can be cut to size for any application. It easily conforms and bonds to sheet metal and other hard substrates and surfaces. The premium adhesion material offers long-lasting functionality even at extreme temperatures.
