I have thr urge to move my Definitive BP2X's from my Bell'o stand to to the wall behind my couch. Does anyone have any tips concerning this? My Definitive's have a key-hole mounting location on the back, but what kind of anchor should I use to keep them somewhat tight againt the wall? I was also thinking of buying some little rubber pads to put in between the speakers and the wall in an effort to keep them as tight as possible. Any ideas?
