I was just wondering because when I set up my HT, I was like: hey if I cross over the lows to my sub... it doesnt really matter to have floorstanding speakers! but yeah there's probably a difference!
I got a brand new pair of RF-82, RC-62 and RB-61 for my HT! I have a HSU VTF3-MK2 and i am really happy with my setup!
