I woke up this morning and thought to myself ' Hmmmmm if the Gramma makes my sub sound that much better...I wonder how my floorstandings (Polk Audio Lsi15) would sound if I placed this baby under it?'

Well...Lo and Behold ! Darn if it did not dramatically improve those too. Two more are on the way. Now I just need to find something to put under my center speaker. Maybe a smaller version? Any ideas?
