I imagine genieclips or RSIC-1 clips would have a similar issue as the whisper clips as far as channel vibration unless the hooks were slightly closer causing the channel to be compressed more and eliminating the possibility of rattle due to weight of the walls.

The acoustical caulking seems to be doing the trick. My application isn't pretty but it allows the channel to move in the slot and so far kills the rattle ... I'm going try this on the electrical wall and see what I think

I'm curious, over time with that stuff dry, crack, expose the metal on metal contact again? It would be a heartbreaker to have some sound rattle return in 5 years knowing it is all now behind the wall.

It's not suppose to. Acoustical caulk is supposed to stay pliable. Exactly how long ... don't know. A quick google came up with this: Acoustical sealant has the capability to permanently retain its flexibility, allowing it to work effectively for a very long time. You can think of it as a non-hardening caulk. I imaging you need to check with the manufacture of the product you're using to get a real number.

You can think of it as a non-hardening caulk. I imaging you need to check with the manufacture of the product you're using to get a real number. They use the word 'permanent' but in reality environmental conditions (low humidity) along with mechanical pressure (in this instance the constant movement of the clip up and down) could eventually sever the material. Unlikely? Probably. I just hate the what ifs. Considering your project is as far along as it is, this is probably a solid solution. Going back to a design phase, these are some of the ideas a person ends up changing. Maybe you would have opted not to use metal channels now, or perhaps you would have found a rubber clip system, etc. Funny how much you plan these out and can still come across changes you wish you could have made or thought of earlier. Grab that sub and crank up some low frequency noise in the room and see if anything else rattles before you close it all up.

Guess I'll goop it on a bit heavier and hope for the best ... Maybe you would have opted not to use metal channels now, or perhaps you would have found a rubber clip system, etc. Yup! If it did it again I'd skip the clips and maybe the channel. BTW the life-time of rubber is also limited ... Grab that sub and crank up some low frequency noise in the room and see if anything else rattles before you close it all up. The problem with that is you need to close it up in order to check it I guess you could close in one layer, check, and then do the next ... but each layer changes the dynamics

In retrospect do you think resilient channel would have been a better option?

It's about all you can do.

I went resilient and screwed every 6 inches. Still had a few random rattles in corners due to sub loading. More screws fixed it up. A-ok. No easy way out.
