My better half has finally given permission to seriously plan the basement and get started soon. So my plans of the the past couple years are getting back into business. I've learned a lot from the other builds and discussions here, so thank you all very much already.
The theatre is an important aspect of the basement, but will be just part of the overall open design. The attached design shows the general layout - any suggestions or comments are very welcome. The drawing is 2D, I haven't tried 3D yet.
General notes on the layout:
The second row is seating is raised.
Speaker placement will be a challenge in this design (especially side surrounds).
I will use an acoustically transparent screen 2.35, with three matching channels behind and two subs.
HT equipment will be below the stairs, in the area that bumps out toward the theater.
The two cross beams in the ceiling are shown, and present a challenging location of support poles (shown in the drawing moved 30 inches down the pole away from the theater). The poles haven't yet been moved, but can be for a few grand.
There will be a half wall behind the second row of seating, maybe a bar at the the top of it for a third row of seating for stools.
Current bar location is shown, but across from the exercise room may be a little odd.
9' Pool table and 10' shuffleboard are shown along with a cocktail table just for reference - location not fixed.
The play room as shown will eventually be a wine cellar when the kids grow up.
There is storage outside the play area as shown.
Ceiling height will be just under 8'8" in most areas. The beams are 7'10" and 8' clearance. There is a lot of HVAC and plumbing below the joists north of the northern-most beam that runs parallel to the beams that is also 8' up. So there will be a very wide area of the space at the lower height, including the northern-most beam and extending for 100" in width. The HVAC tapers from left to right along the length of the beam.
Wall framing inside the foundation walls is required in the theater area due to plumbing pipes inside the foundation walls.
The foundation walls are superior (pre-cast concrete and styrofoam with built-in studs), so I have some room to play with for speaker placement in-wall on one side of the theater and behind the screen.
That brings me to one big question: speaker placement.
I know I am sacrificing audio quality by not controlling the space with a dedicated theater room. I am concerned with audio quality. I am not concerned with isolation.
What considerations must be made for speaker placement? Where would you put the non-screen wall speakers? What would you change about the design?
