MY QUESTION: How do I safely attach an articulating mount (tilt/pan) for a 75" LCD TV to a "sound deadening" wall that uses resilient channels?
Thanks to the miracle of the StackExchange Home Improvement answer to someone else's question, I learned that the bizarre insides of my wall are so-called "sound deadening:" drywall, attached to horizontal metal 'resilient channels,' attached to wood studs, attached to concrete cinder block.
I had never heard of such a thing and was image-googling "horizontal studs" when I found the pic that "Ecnerwal" shared in the linked post (reposting here to save you all a browse): Except I don't think my building includes all the fancy layers, it's just drywall. :/
So what should be my approach?
- Anchor the mount to the wood studs, through the metal channels?
- Anchor to the wood studs, avoiding the metal channels?
- Anchor directly to the metal channels, avoiding the wood studs? (seems risky)
- Forget both the studs and channels, just mount a plywood backing plate to the drywall with 18 drywall anchors and attach the TV mount to that?
I really don't want to have to open up the drywall in the living room if I don't have to. Not finding any info about how to deal with resilient channel walls. Would love your thoughts.
