I am trying to figure out the safest and cheapest way to wall mount my rear surround speakers. Granted that I live in a college apartment and floor mounting has caused damage, I was tring to figure out what is the best way to mount the speakers. I understand you flip it upside down, but can i mount it with a simple screw in the wall or should I go about it a different way. I am not looking to spend much money on fancy brackets. I just need an inexpensive way to secure my speakers to the wall. Thanks.
