Design Engineering DEI 050200 Boom Mat Sound Damping Material with Adhesive Backing, 12" x 12.5" x 2mm (Pack of 2)

Good value.... adhesion was great...easy to install...helped was sound quality no rattling...ease to cut laid speaker on top went around with box cutter twice... didn't really sniff it it wasn't your momma's panties.lol

Boom Mat is an awesome sound reducing insulator. This past weekend , August 2022, I covered the complete interior floor of my 1933 Ford 3 window coupe, It's important to cut a cardboard template of oddly contoured spaces , then transfer to Boom Mat for an exact fit and professional look. Sorry no images are shown. I'm following this up with DEI under carpet sound insulator , then carpet. The Hot Rod air conditioner and sound system are definitely going to be enhanced as well . 8hr install time resulted in a spectacular finish. Highly Recommended

El paquete llego en buenas condiciones, se observa buena calidad, se pueden realizar los cortes de manera fácil para su aplicación ya que no es muy grueso, mejoro el sonido de las bocinas y le da masa a las puertas, faltaría ver su comportamiento a largo plazo.

This stuff isn’t just for automotive use. I assembled a new computer system recently and the combination of motherboard fan and a big 110mm case fan set up some vibration. Since computer cases have large expanses of mostly flat sheet metal, there was an annoying resonance setting up in the case. I knew exactly what I needed and this product solved the problem; I knew it would. Vibrations have been eliminated and the system is practically silent. Great stuff!

Very effective, easy to put down
