On your additional layers for the ceiling are you leaving a small gap between the wallboard and the ceiling boards each time? It's been difficult finding information regarding the second/third layers as the butt up each time to the wallboard.

Note: the plan below is a bit out of date with probably the biggest change being that the top and bottom center speakers are now planed to be just one VP180ow behind the screen and a M3ow for center height. Most other things are little changes like adding alternate rear speaker wires at approx +/- 160.

The grey areas are the angle ranges for the bed speakers (angles in red outside of walls)
A red + indicates a speaker wire in the ceiling and a red T indicates a speaker wire in the wall. The 7 inner +'s are for tops and the rest are for heights. The blue line indicates as step down into the front of the room. The main seating is on this level. Bed speakers are red and heights and tops are purple.

Very nice.
Another great build thread. Interesting stuff.
The room will double as a bomb shelter i expect.

Inside floor joists: safe&sound | air gap | safe&sound
then nailed on the bottom of the joists 1lb MLV | over that clips & channel (which by default is an air gap)
attached to the channel ... the HT ceiling (which is what I think your talking about) ...
no gaps:
1/2" OSB | 1/8" FloorMuffler | 5/8's wall board | green glue | 5/8's wall board


Note: The boards are staggered so the seams don't fall in the same place.

No, I meant where the wall and ceiling meet. On the first layer on the ceiling there's supposed to be at least a 1/4" gap from the edge of the ceiling board and the wall studs. I was just wondering if you left a gap between each subsequent layer of ceiling boards.

The ceiling is complete and now working on the walls. I've been putting finalizing my in-wall/in-ceiling speaker connections ... It's time to commit so I can prep the walls and ceiling for them.

The plan was to find a connector that was attractive and unintrusive as there will be lots of these will be showing. It needed to be less than an inch deep to fit with-in two layers of wall board. I also wanted something which didn't stick out too far from the wall.

Needless to say, I didn't find anything I wanted ... so I did what I always do ... designed my own. I had two versions in mind: one with the typical dual banana plug spacing and another which I though might be more interesting ... so I prototyped that one first:

I designed it so it would accept a snap on cover ... just in case I didn't want to see the connectors. Anyway, I'll probably prototype the other soon.

I know it is still the construction phase but i have to say, this room looks really ominous. You sure it is going to be a home theatre?
