I am planning a dedicated theater room right now, and I am intending to use resilient channel to hang the 5/8 drywall on the walls. One thought that came to mind is how do I hang my RS-7 surrounds on these walls? I know I have to avoid grounding the drywall to the studs, but what can I do to mount my 24lb surrounds? There are keyholes located on the back of the speakers, and the intention behind them is to drive 3" wood screws into a stud in order to mount them. I can't do this, though, because that would ground the drywall to the framing. Is it reasonable to think I could just drive screws through the drywall into the resilient channel, and hang the speakers from that?
