Again, I realize that density is not the only factor in determining a material's ability to absorb low end, but... it's all interesting.
Andre's right, of course. Rigid fiberglass or mineral wool is what you want for low end. Foam, regardless of density just isn't a stellar performer on the low end for the reason you stated...there's more to it than density.

The point Andre's making about predictability and repeatable results is a very important one. You want your treatment solution to be as dependable as possible.
