The duct work has supply ducts for finished basement, formal living room and formal dining room upstairs. But these ducts are between the ceiling joists. So they are not a problem. They are atleast 8 feet tall. The only problem is the return duct for the basement is at the bottom of the closed area.
However, I might be warming up the idea of knocking down the corner of the bathroom that is right next the duct and creating an angled-doorway, and making it the main entrance to the theater. I will post some sketches of this idea later for comments.

So how many seated bodies are you looking to accomodate?
Very interesting point about the projector being in the walkway of the second row. I calculate the bottom of the projector to be about 7ft from the top of the riser. Is that enough headroom or still a cause for concern ? I admit that someone could reach up and touch it easily, but I think it is the accidental head-bumps that we are trying to avoid, correct ?
As you can see from the renders below, I am trying to create seating for 5.
Here are some quick renders and some line-of-sight calculations. I appreciate everyone's input and comments.
Here are some of the design questions I am wrestling with.
1. The two longer sides of the theater are external concrete walls. I am thinking the following design for the walls along those sides.
(Concrete wall) + (faced fiberglass insulation) + 5/8DW + GG + 5/8DW + 2x4 Studs (not staggered) + 5/8DW + GG + 5/8DW
Do I have it right ?
Do I need to go with staggered studs on the wall next to the external concrete walls ?
2. I think I understand how to attach the drywalls to the ceiling joists using RSIC clips + Hat channels. Can someone point me to a diagram on how to attach the DD+GG layers when there are no accessible ceiling joists ? I have this problem along one side of the room where there are three big ducts connected to the ceiling joists.
3. Finally, I guess somewhat a rookie question. If I need to get a building permit from my town, do I need a set of "official" engineering drawings ? This is the first time I am constructing anything in my house and want to know if my own "engineering" drawings are acceptable. I am quite handy with Visio
