This stuff works just like Dynamat it is made of the same material. If you are looking to improve your sound quality by ridding background noise that interferes with noise from speaker vibration this is key. It really cuts the outside noise from being projected through your speaker. This product is super cheap and it works the same as Dynamat at a fraction of the price!

This stuff really works! It sticks really well and is easy to install. The instructions say to put the entire sheet over the speaker mounting hole and then cut out the center. Use the cutout piece on the outer wall behind the speaker. It's easy and the included plastic tool works very well, especially on uneven surfaces.

The reduction in vibration is immediately apparent and the bass sounds better.

A good product at a great price.

I had some vibration on my front door speakers, so i ordered this, thinking it would help. Actually it did nothing in my opinion, and im only kicking 100 watts out the speaker. Also i had to cut the plastic lining the door has, which is suppose to stop car, So now my left foot is always cold because air comes in. At least the speakers stay cool. The installtion tool though is sweet. I used it instead of dynamat roller
