Okay. I have been using AVS forums for years, albeit off and on. I have the green light to go ahead and finish my entire basement, which will include a guest suite, bathroom, fitness area, large open play area, and a HT. The dimensions of the HT are 17' 5' wide by 18' 8' deep. I can do deeper if need be, but not wider. Unfortunately, the guys that build the house tried to make things somewhat difficult for me, and I already have issues coming up. Here's the first string of questions related to the planning stages.
My house was build with ibeams for joists. They are basically 2 2x4's with a slit in them and them some plywood looking material making the vertical part if the I. These are spaced at 16".
The first issue is that there are plumber pipes, gas lines and a HUGE HVAC thing running perpindicular to all the joists. They are pinned to the bottom of the joists, running perpindicular (which saved them time and made a HA for me). Most of the pipes and gas lines are small....so, here is question #1:
1) Can I use some sort of Hat and decoupling system to lower the ceiling about 1.5 from the existing joists, leaving room for the pluming and gas lines? I know that these systems are not cheap, but moving the gas line alone....oh I can only imagine what that would cost.
Second issue is the seating issue. I want 2 rows of 3 chairs. I have lots of room across for these, but depth wise I am concerned. I read that I should have the front row 2x the screen size in distance. For my 100" screen, that would mean over 16 feet out and the room is only 18' 8' deep to begin with.
2) Does the x2 rule still apply when there are more than one row of seats? I made a tape mock up on the wall of 100 inch screen and 16' back seemed really far back for row #1.
3) I have a big old HVAC run that runs the length of the house. It is on the theater ceiling as depicted below by the double line. Circles can be ignored. Spaced don't work for the ascii image.
Should I just move the N face down so the HVAC is behind the wall, for simplicity sake and a give up those 24"? That would take the room down from 17'5" to 15'5" but would make framing easier. I could gain back the space if I used a Hanging Interior Soffit.
More questions to follow.
