If anyone has found a nice solution to keeping the Sunfire True Subwoofer Signature in place on a hardwood floor, I'd love to hear about it. It's a little distracting to have a 50+ pound box hopping around during explosive movie moments. I have the included larger feet installed, but it's still moving around a bit and is probably going to scare my wife and guests (it already made the dog freak out). Without the big feet, it was moving during loud passages with me standing atop it (good way to make yourself queasy :-)).. Obviously I'd like something that would not destroy the floor (ash planks), but as is it's not going to be good for the floor so I'd take just about suggestion at this point short of something truly hideous-looking.
