Has anyone used the Carr + 2" Foam egg crate as the top layer? Using 3m super 77 spray adhesive to apply.

I would think it would provide additional sound dampening and also isolate different sound frequencies that the Carr does not. (lower = Carr and high = egg crate)

This is a technique I picked up on researching my car audio installation. Used Raamat dampening with a layer of Ensolite on top which dampens the higher frequencies. In fact, Ensolite might be a good top layer instead of the egg crate. It's peal and stick.

The inner engineer in me is contemplating doing this and taking measurements with a pocket RTA.
