Thanks Dan. I hope I stocked up enough, I have 2 cases of the green glue acoustical sealant and (3) 5 gallon pails of Green glue. If I have enough extra I'll add another double layer of drywall w/green glue on the wall in our storage room.
Oh yes, and I did run flexible conduit to each of the speaker terminals and the projector. It was easy enough and pretty darn cheap.
That being said, I did start on the ceiling. I was able to get one layer up so my first attempt at green glue will start shortly!!! The most annoying part was trying to gap the layers of drywall on the ceiling with 2 people without a drywall lift.
