Diki, I put my speakers behind me and close to keep things as safe as possible. But there are still those STUPID people who constantly move about the room and get into areas they're not supposed to.

I occasionally sign waivers in job advance against possible liabilities such as a fallen speaker, etc.

From the comments, it sounds as if the floors would definitely be less effective - quality sound wise.

Gary, L1 = expensive. (I know, what is more expensive than a suit and I think I'd give up stereo?
