Yeah but am I ever glad for the opening. I was dieing to use that pic.
It's odd about the blind testing. The room was work. The panels were work. Re-configuring the gear 7 times was work. Blind testing or even a sighted comparison isn't work I care to part take in due to my belief that my observations are likely meaningless. However once I get on the REW band wagon doing a FR plot @ the listening position w/ and w/out panels both here and in the living room seems worth while.
Right now I have a really strong urge to elevate my speakers a few inches.

Eddie has some 2" thick solid Mahogany ... you get the picture.
