Update with pics of the completed room. The movie premier was on June 10, 2012.
The Austin Home Theater DIY construction video:
Well it's finally time...my own build thread!
I'd like to start off by thanking everyone on AVS Forum. I feel so lucky to have all of you here to help and support me on this journey!
A little background: I'm a senior in High School looking to finish this theater so I can get some time in it before I have to leave for college. My mother, two sisters, one brother, and five dogs just moved into a new house. At our old house I had a projector set up with a cheap box sound system so I'll be reusing the projector but getting new 5.1 surround.
The room is in the basement which is currently home to my sisters bedroom and an (almost) complete bathroom. The theater will be in a section of the unfinished half. Room dimensions are 11ftx12ft with 7ft ceilings. The plan is to have a couch and recliner along the back wall with a 96in 16:9 screen. Soundproofing measures will include staggered stud walls, decoupled ceiling with whisper clips, fiberglass insulation, and DD + GG. Soffits will be along the two sides and back wall to hide some ductwork and hold recessed lights. Floor will be wall to wall carpet.
Gear which I have:
FL and FR-Polk Monitor 60
Subwoofer (considering Bic f12 but friend has offered a deal on B&W ASW1000?)
Surrounds (Considering Dayton B652)
I'd love to have it operational by Christmas (at least a screen and sound) so I'm looking forward to some hard work after school and on weekends!
Feel free to share any suggestions/comments/words of support and thank you all!
The screen will be on the wall which currently has empty studs from previous construction.
The back wall will protrude out from where the concrete block comes out.
The doorway on the screen wall will be sealed and the entrance will be through a door underneath the HVAC trunk in a small hallway.
The outlet on the concrete block wall was moved to the workbench area of the basement and I put up the rigid foam insulation on the wall.
From the looks of it tho - you are going to blow them away with how great it's gunna turn out. Nice job on the rigid btw.

The framing is coming along nicely. I hope to have all of it complete soon so that I can begin the electrical (my favorite part of the build) this weekend.
I have a question for all of you experts. My plan is to recess my projector into the staggered stud wall so that the lens is just about flush with the inside drywall. This is to maximize screen size in my small space because the projector (Optoma HD20) does not have a very good zoom. My plan is to build a projector "backer box" according to Ted White's specifications. This will be an MDF 5-sided box with a layer of green glue and cement board lining the inside. Does anyone see a problem with this or have a better alternative from a sound isolation standpoint? My concern is that this configuration is meant for smaller boxes like for recessed lights.
My other concern is ventilation in the box. It will be open in the front and the projector has a front exhaust. The room air return will also be located in a soffit above the projector to remove heat. Do you think their will be enough airflow to reach the projector intakes along the side and back of the unit? I would add some kind of vent and possibly a fan in the back of the box but I feel like this would then be detrimental to sound isolation.
As always, THANK YOU!!!
Nothing like a shipment of Green Glue to get you excited!!!
After reading about this stuff for the last few months it feels surreal to actually have it in my own house. Time to throw the builder in me into high gear so I can get to installing it. Now to find a contractor size caulk gun...
I have to thank everyone at The Soundproofing Company one more time. You gave me the greatest advice I could ask for and allowed me to get the best sound isolation I could with a limited budget. Everyone should call you guys for everything relating to soundproofing!

Staggered stud wall construction:
I also picked up two wall sconces for the "entrance hallway":
And the IR Repeater System came in the mail:
I also went to a local lumber yard to order a door. I asked for a solid core pre-hung unit cut down to the height that I need. They will call me tomorrow to give me a price quote. Should I be looking for anything more specific in the door? When I told him solid he said Masonite. Is that correct? I might end up just getting one from Home Depot or Lowes and cuttting it down myslef if they charge a high fee for the cutting.
Thanks for taking the time to follow this!
You should go to a real door shop. Home centers aren't too good at special orders.
Masonite is a brand name - one of many.
Crossed out in red is brickmould which you won't need.
Kerfed weatherstrip highlighted blue.
Note the top and bottom rails are only 1.5" or so. If you cut more than that off the door you will get into the particle board core. It shouldn't be a problem to do so, although the door will be more easily chipped on the bottom since the particle board is not that tough. I'd recommend fortifying the bottom of the door by painting wood glue into the exposed particle board.
A router with a straight bit is the best way to cut the door without splintering the veneer. Second best is to use a circular saw with a fine blade. Score the veneer with a utility knife and apply blue painters masking tape to the door to help prevent chipping.
You may find a door shop willing to cut down a stock door for you. Otherwise you'll end up having to do it yourself and route the door and jamb for hinges. Try to find a door specialty shop that has the tools to prep the door in-house. Most lumber yards buy their prehung doors from a wholesaler. The wholesalers are generally not too cooperative on doing custom work.
Give me a zip code and I may be able to locate a supplier for you.
