For the next 4 years the room more or less was studs with a single 1/2" layer on the ceiling to hold the blown insulation in the attic. The outside walls (north wall where the screen goes and west wall with the window) also had blown insulation in them.
Finally, after 3 years I began to see a bit of light at the end of the tunnel when my wife asked what it would take to put in an entry level projection system. $1800 later (for Optoma H31, 100" screen, onkyo 75w 6.1 receiver, dvd player and velodyne dls-4000r sub) I was in business. Football never looked so good. Even on a 480p projector it was fantastic!!
Wish I had pictures of the room before I took everything out for drywall but I never expected to not be putting stuff back. Basically I had finally found the soundproofing solution I wanted to go with and began scheduling the drywall installation (waiting does not save money here -- the building boom is ridiculous right now and every 2 months things go up 5-20%, yes, that's right -- including my dang taxes -- almost a 50% increase every year for the past 3 years). Okay, sorry for the tangent, back to HT.
After reading here about how well green glue was working for people and it would cost the same to do 4 walls and a ceiling as just 2 walls (well, without drywall and labor added in, even with that it's still cheaper), I was ready to go.
Here's the room after my brother and I spent a weekend doing the electrical. That consisted of moving all the boxes out to support 1-1/4" wall thickness, adding cables and switch for sconces, moving boxes up on the wall for the cabinets going in for the wetbar, adding a light in the hallway for the "Theatre" art deco sign, adding a phone line, network line to adjoining bedroom, running a dedicated 20amp line from the circuit box to the equipment closet for just the equipment, taking the fan off the 20amp circuit in the room (which the sub would be on) and puting it on the kids 15amp room circuit and adding a light line and switch in the regular closet. Oh, and I forgot to mention running the speaker/sub cables in the attic while it was 130 degrees up there. Did you know you can actually burn your hands on the studs while you hold on like a monkey trying to run the cable? I have never sweated so much in such a short time in my life!! I had to come out every 10 minutes or so because my head would start to ache -- didn't want to get heat exhaustion or worse up there!!
Oh, I also spent the next 3-4 days running the insulation in the south and east wall as they were interior walls and weren't blown.
West wall (window wall):
North wall (where screen, sconces, and Art Deco architecture will go -- imagine how much 46 sheets of 5/8 4x12 drywall weighs!!):
East wall (wet bar -- cabinets along the bottom, on the left will be a small fridge below, 8 head soda fountain dispenser up top, popcorn machine, then sink with cabinets above the sink area):
South wall (regular closet, and equipment closet):
