Sonic Barrier 1" Acoustic Foam w/PSA 18" x 24"

This worked great for my AR9-LS rebuild. Very easy to cut into the proper sizes and install!!!

I have just finished installing two home theater systems that used a large number of ceiling and in wall speakers. I purchased this damping material to place behind those speakers. It worked very well in that the bass immediately tightened up and the definition of the sound became very focused. We were installing fairly expensive speakers throughout (BG PD Series Speakers) and this was a excellent way to ensure that you would hear the speakers as intended.

I was amazed and pleased at the difference that adding this material made... well worth the added investment.

Not the best for dampening custom speakers. deadened but not in a smooth warm way i was expecting. but cheap and easy to use.
