We just moved into a new home (to us) a few months ago. First floor was completely gutted, new kitchen, laundry, floors, etc, etc. Now that the first floor is complete I have a little money left over and would like to build a dedicated theater room.
The basement was finished when we bought the home. I had the guys who did the first floor construction build a wall with door to enclose a space I could use for the theater. I used Roxul Safe N Sound and double drywall for the little good it will do. Since the majority of the room was finished it's not worth it to rip out all the drywall and start new. Drywall ceiling will make it challenging to run cables, but I'll just have to cut holes and feed wire through.
I'm about to paint the room. Flat black on ceiling and screen wall. Likely a dark burgundy on the surrounding walls. The window wells will have blackout blinds.
I've got a soffit enclosing what is likely an I beam and something else. I'm going to pop a hole in it shortly so I know exactly what's inside. The soffit is about 14 ft. back from the wall and i'm not sure if it will interfere with the projector placement. I was thinking about mounting the projector flat under the soffit.
Dimensions of room are 12 ft. wide x 31 ft. long x 7.4 ft high. The area where the screen will be placed has a bay. The bay width is 5 ft. expanding out. The soffit is 14 ft. from the bay wall. The soffit itself is 25 in. wide and runs across the width of the room.
My thoughts for a screen are a 114 in. Carada Criterion 1.78 x 1 classic cinema white, 106 inches wide by 62.6 inches high. I'm guessing the screen will need to be fixed to some kind of post structure from ceiling to floor, about a foot or two from the bay wall. I will have about 2 ft. open below the screen where I would like to place my center channel, and about 4 inches open from the ceiling. The placement and size of the screen/center channel has me a little concerned. Any advice would be appreciated here.
Projector will be a Sony VPL-HW50ES.
Speakers are B&W 804s, HTM4 and some Polks as sides. I need to replace the Polks and also buy some rears. Looking to match my B&Ws. Sub is an Epic 18 in Dynasty and will likely be placed at the side or back of the room.
Amps are Emotiva XPA-5 and XPA-200. Preamp is Marantz AV-8003.
Any advice at all is appreciated.
Here are some pics of post construction pre-painting. I tried to show the bay area where the screen would be and the soffit. Ignore the wall speaker. The home's previous owner stuck some wall spears around the basement in without any logical placement.
