Well, staying up until 1am this morning and then back at it at 6:30 really paid off. Drywall is being hung as we speak, but here are a few shots of the room as of this morning.
First, a shot of the rear enclosures mounted in the wall.
I ended up using R-13 insulation around the perimeter, and R-30 in the ceiling and soffits.
Below is a shot of the rear wall, showing both enclosures and the cabling for the projector run:
The front wall. Front wire pull throughs are all at 24" above the floor. You can also see half of the 64 sheets of drywall that were delivered.
Finally, a picture of the cabling coming back to the equipment rack. I ended up going with 3 boxes so that things wouldn't be too crowded. AV cables are on the left, and all of the speaker and sub cabling is on the right. There is also a 100 foot CAT5 run going from the rack to the office, which is above the crawl space at the opposite end of the theater. This will give me a hard connection from the router there to the theater.
I'll post some additional pictures once the crew leaves today.
