Wayne, My room has 9' ceilings, real plaster walls on lathe, and an old hardwood floor that's the thicker kind, on a very good slanted-board subfloor, with one area rug in center under a coffee table, and no curtains. I've just had the Stage 4's tipped up in front w/ a piece of 3/4" plywood...think I'd be a candidate for the 4" stands? They sound good the way they are...but....always looking for something else to do. I finished my "SET-style" xover and it sounds great.
