That seems doable
I have updated the drawings
-I tried to find a way to put the air supply in front and return in rear. The room does not easily allow for this. I placed the supplies venting down from the soffits by the seats and the return is in the front left corner of the room. I am also trying to see where i could place the wall mounted mitsubishi unit (w 31.5 inches d 10.1 inches h 11.63 inches) if needed. I might get a few more HVAC guys out for opinions. Any other opinions out there for my HVAC situation? I may rough out for the ductless system in case the duct work does not get the job done.
-Having a hard time spacing the soffit lighting (front, back, sides), even distance between lights? equal space from colomns? number per wall?
-I will also have rope or black lights in light tray. Verdict still out on star ceiling (fiber optic, Painted, none). Sorry Spaceman your theater is just too inspiring.
-4 Step lights
-Riser calcs suggest 13.5 inch riser, I think 2x12 and 2 sheets osb will get it done (it is hard to estimate head locations with only chair spec sheets). Those who used 2x12's for risers, 2x6's for steps, does it bother you that the first step is taller than second, is it even noticeable.
Here are the pics, sorry they are a little rough, my printer was giving me issues.
Any feedback would be greatly appreciated
