I had towers in a bedroom set up. I made stands to raise them up and then lifted the backs to angle them forward. My center was mounted above the TV and angled down. All three tweeters were aimed at the pillow, or listening position.
A guy can get pretty handy if he needs to. I had a 7.1 with Monitors 70, 40, 30 and CS2 with an Epik Empire. The room was only 14.5 x 10.5. Had 50" plasma as well.
Went to Lowes and got a garage storage rack that had adjustable shelving with thin wood shelves. Painted everything black. Placed in the corner, the bottom shelf housed the sub, above that was amp, above that was AVR. The blu player had it's own shelf. The L main sat on top of the sub, wait, I think I have a pic somewhere.......
Nope, all I could find was the rig I had before I put together the storage rack. I had placed a 2 x 2 block of wood in front of the rear speaker feet to angle it forward.
