Because of where my front stage is being mounted I have a concern about reflective surfaces were the left and right front midranges and tweeters are going to end up. I have plans for them to be mounted behind the dash out in the fenders. To refresh your memories   https://www.the12volt.com/installbay/forum_posts.asp?tid=96959&KW=jack+finks (and I hope I'm not breaking rules here as I have not found a discution of this subject, though it does relate to my install)

I plan on use Dynamat extrem but that has a foil suface. And it is the foil suface I'm concernd about. The underside of the raw fender would be painted metal anyways. I guess I could follow Home theater practice but I have concerns with space and wieght and the fact that its in a car. The area in concern is ruffly cylindrical. I am toying with the idea covering this area with sweude. I would like to get input from the folks at this forum. Remember that this dampaning is for the Mids and highs only as the mid-bass and woofers are in different locations.

Thanks in advance

Highlight the word and click the insert link icon: recomend non reflective surface matterial -- posted image. then paste in the URL.

Yes, I've used that kind of foam and it is a really good dampening product.  It's down side is it must be used in a protected area as it's not very rugged.  I'd use it over the dynamat.

Thats the rub. If I put a mesh panel in where the inner fender used to be then looks and protection are not an issue. I don't know yet I I'm going to do that untill I can hear how it will effect the sound. OF course with Dutz fasners they would come out easily for judging...

I deffinately want to deaden and reduce the refelections as much as I can. I feel that it is going to be one of the challenges I will have to face by going this route of speaker placement.

A foam moch up of the dash is soon to my future...
