I first came into contact with this stuff in 1992. It was pretty new then, and many people disregarded it at a "tweaker's" product. 12 years later, it seems to have been cloned by every auto manufacturer and sound deadening company.

This week it's my new best friend...old school sound deadening representing.

Good looking friend you got there Adam. Are you buying from e-speakers or do you have another source ...like wholesale maybe??

 

mmmmmmmmmmmmm constrained layers

 

The product originally was distributed exclusively by Orca Design. The price has come WAY down from what it used to be, so I'd consider the e-speakers price pretty close to wholesale.

Haven't bought any yet...but it's on my list. (and boy is my list getting long)

Yes it is similar, but it's 3 times as thick and made with heavier materials.
