Review on 🔇 Dynamat 10415 10x10x0.067 Thick Self-Adhesive Sound Deadener with Xtreme Speaker Kit - Pair: Reduce Noise and Enhance Audio Experience! by Mardrequs Dorsey

Dampens vibrations well. But it cost too much. Did you know that you can walk into any Pella window shop and buy practically the same thing for about half the price? It's just an aluminum based butyl tape. The same material is used in roofing, building and window installation. It's a little heavy, but you can always try a layer of Pella tape and if that's not enough, add another if needed. There is nothing magical about their wording, although they would like you to believe that.
