隔音-Dhyana门Kit

Speakers are mounted on a very flimsy sheet metal door panel, and the metal sheet may be vibrating while there is a sound impact. On the other hand, the flimsy metal door panel will vibrate while driving on an uneven road. These vibrations create resonance noise in the door. To reduce the noise, you must strengthen the door. Just as the sound box of the home audio, you shall strengthen the door to be a sound box! Dhyana Door Kit is a elastomeric butyl and aluminum constrained-layer vibrational damper. It conforms and fuses easily to sheet metal and makes the flimsy door with holes to a sealed solid non-resonant sound box. With a new excellent sound box, you can enjoy the pure and quality music of your speakers! It is the most important step for car sound insulation. We can do OEM for you!
