How very interesting that this has the subwoofers built into it as opposed to being in a box somewhere else in the room. I know they say that bass isn't directional, so it guess it makes sense that it wouldn't have to be a separate module. I think the one thing I would worry about is the sound bar bouncing and rattling around if you don't have it mounted to the wall or something like that. It seems like you would get some vibration like the trunks on those cars that drive really slow through town :)
