The hard back doors are on the outside. Where I am standing is quilt. You can tell quite distinctively how dead it is in there. Unless the sound is going up 90 degrees to the ceiling and coming back down into a 3x3 ft hole, I am as quiet in there as if I was in a padded cell (which I fortunately have no experience with yet).



I meant that frequencies that the quilt can't absorb (probably all the lows) and going through the quilt, hitting the hard surface of the doors and bouncing right back in. Maybe I am wrong and hopefully someone who knows about this stuff will jump in.

I did a lot of reading at gearslutz's acoustic treatment section and I am assuming that would be the consensus of opinion on your setup.
