[QUOTE="chris229, post: 26278, member: 542614"] Don't do it, it's worthless. The only way to deaden a box that is worthwhile is internal bracing. All sound deadening mat and spray do is add weight to the panel to change the freq that it resonates at to a lower one. For this to have a good effect it needs to be a considerible percentage weight change to have a worthwhile effect. This is good for light metals like sheetmetal or plastics but for steel or heavy wood like MDF. You would need so much of the stuff to have the weight to change the res freq for heavy weight panels. It would be better to use concrete or lead to add weight or more bracing. But because were talking about Speaker boxes you need to add bracing because any flex = lost power. [/QUOTE]
