Deadening: Speaker Kit

The HushMat speaker kit creates an anti-vibration gasket between the speaker and the metal door. When the speaker cone moves the vibration of the speaker does not transfer to the metal door and create any potential distorting vibration or artifacts. Includes enough material for minor application to the outer skin of the door to add additional rigidity to the door for a more immersive listening experience.
