Sound Treatment Idea...

I hung a whole bunch of 2'x2'x1" a few months ago with just T-pins and they're already sagging in places so....bump

Hence the self-adhesive foam-boards. They won't sag as there is even adhesive (in theory). Like I mentioned, I may glue it strategically as well for reinforcement.


Btw, did it improve your room as you'd hoped it would?

Yessir it helped a lot, especially the bass traps...so do you get these foam boards at like a Hobby Lobby?

So I found adhesive foam-board at Hobby Lobby


Oh sorry, I missed that somehow...yeah I was thinking plywood but this makes much more sense.
Are you planning on doing anything around the edges or are you just going to let the foam show?

The foam-board will go to about 1/4" from the end of the Auralex panel the way I see it.

Michael Five... you are talking crazy 

Consider putting spacers between the foam and the wall, or attaching the foam squares to a wood frame and hanging them with picture-hanging wire. Adding an air gap will lower the effective frequency range, which is severely limited with 1"-thick absorbers.

As for where to put them, they're going to be most effective at the closest reflection points to the right and left of the mix position, and on the ceiling above it. The standard method is to have someone hold a mirror up to the wall while you sit in the mix chair. When you can see your speakers in the mirror, that's where the absorbers should be centered.
