sealing resilient channel gaps - see pic

[mncheetah]

I am about to install my slot resonators. I have it all framed out and drywall installed. I just need to attatch the boards to the studs and I'm concerned about sound leakage.

Sorry about the crappy picture, it's easier to visualize than it is to draw. What I am concerned about is the air passageway that goes between the boards on the slot resonator and through the gap that the resilient channel creates underneath the drywall. How do you seal this? The obvious answer is to squeeze some caulk into there, but I'm going to to be burlap behind the boards on the slot resonator, and I dont know if the caulk will stick to this. How are people doing this (sealing off the gap that resilient channel creates on edges).

Thanks in advance.

Your drawing is a bit confusing - are you trying to mount a resonator into a ceiling??

John! I don't believe you said that....this is the first time I think I see something clearer than you

Its a wall -- "front view" is looking at the wall, "top view" is looking down at the wall from the top.

In answer to the question, I'd put a strip of wood down the edge to caulk the wallboard panel against.

However, I don't understand the use of RC in this application. On the right hand side you have RC mounted wall board which will reduce sound transmission in and out. On the left side you have slotted resonators. Won't the resonators let sound in and out of the studio BIG TIME? I would think you'd want a full RC wall, then boxed resonators in front of that.

You are correct, this is a wall not a ceiling, the unfilled brown rectangles are the studs.

I got the idea of building the slot resonators into the wall from John Sayers' diagrams - I have a very small space, half of a basement, to do this in and every inch helps.

As far as letting the sound in and BIG TIME, that's my whole purpose of this post, to seal the edge area off. The top and bottom are sealed with the top and bottom plates(2X4).

I'm attatching 2 pictures of my situation.

...looking between the drywall and the studs...

I know this CAN be done, otherwise John wouldn't have it on his site.
