we just got our focal/mosconi shipment in. this new sound deadening material looks awesome. figure dynamat with the addition of the insulating foam already on top. i have no doubts that it will perform better. before we had to lay the dynamat and then add the foam on top. now we can do it all in one step. focal has been known for their sound quality, so i am puttin my faith in this product and an going to be installing in one of my vehicles. for those of you interested, it does cost a bit more than dynamat, but the quality of it and the time it saves on install makes up for it.
