Francis,

I recently built two amp iso rooms into the corners of my big room, they are 7'-4" high, 7'-8 wide at the back tapering to 6'-0" at the front and roughly 8'-0" deep tapering up to 9'-4".

So two walls have a 90 and the others are at least 7 degrees off. the floor and ceiling are parallel.

The amps sit on the back wall aiming toward the door and I have 1.5" 703 on the back and 90 degree side wall. I'm hearing a ring from the Gypsum ceiling to the concrete floor which gets better with packing blankets but I'm looking for a more imaginative solution than carpet on the floor and 703 on the ceiling.

Or is the obvious the way to go?

Thanks.
