I seem to recall a while ago seeing a sub that was very flat looking (say 5" high) and completely round (thing giant extra-strong mint!) that was designed to 'slide' under furniture (ie, anywhere out of view). I think you could also hang it on the wall. Trouble is I have no idea where I saw it. Anyone have any ideas? I have to admit i'm a little aprehensive regarding it's sound quality, especially when it's 'boxed in' under a sofa - what do you guys think? Thanks for any help.
