11x19 Dedicated Basement HT Build
I am currently building a home theater room in my basement and have started the framing process.
Unfinished Room size: 20’8” L x 11' 9" W x 8' 10" H
Finished Room size: 19’8” L x 11' 4" W x 8' 6" H
Basement room with 3 Exterior Concrete walls, Master bedroom is above. Good sound proofing is a must.
The room is odd shaped with a 16" cut in 14' back from where the screen would be at making the back of the room 10' 6" wide. I am building a bump out that will give me 8 more inches on that 10'6" making it 11'2" at the back.
I glued 1" foam board on all the concrete walls and framed 2.5" steel studs, 24" on center.
I am going to put 5/8" DD and GG between the ceiling joists, R19 insulation stuffed between, R1 channel on the joist with 5/8" DD and GG.
I am going to soffit running around the sides and back of the theater, boxing around drain pipes in the back, a HVAC duct on the laundry room side and another soffit on the other side just to match.
I am planning on using drywall grid to build the soffits and use 5/8" DD & GG on those as well.
If I am boxing in the soffits with DD & GG around the drain pipes and HVAC Ducts do I need to treat any of those with insulation? This also includes some of the hard piped ducts to the bedroom above?
I do have one HVAC vent near the rear in the theater room but no return at this time. I feel like I need a return but
I've ran 3 - 20 amps circuits and 2 Ethernet cables. I'm planning on 1 circuit for lights (LED strips in soffit, projector and some LED can lights), 1 circuit for the receptacles, last circuit for PC, receiver, speakers etc.
I'm having a debate on if I should do a AT screen wall that is roughly 18" from the front wall (if it's even possible with my room). I was hoping to use that area for not only the speakers but have the HTPC, receiver and other equipment behind it as well. I'm also trying to figure out a screen size as well.
I was also thinking I could put two rows of seats in a 4-3 or 3-3 config.
1st Row: 9.5 ft from screen wall
2nd Row 15.67 ft from screen wall
I'm tossing around an Atmos set up as well and possibly having in wall speakers on the sides and rear. If I did the atmos and in wall speakers I would build backer boxes.
I'm trying to attach a layout and some current construction pics
Thanks for everyone's opinions and advice in advance!
