Beautiful area you are in, where is it?
Central Oregon High Desert.
What are the dimensions of those 2 rooms?
Theater Raw Dimensions (before acoustic treatments or proscenium) 14 W x 23' 7" L x 9' 2" H (w/o soffits)
Electronics Bay Raw Dimensions 9 W x 20' 6" L x 8 H
Theater dimensions will be modified somewhat by proscenium, drywall, soffits, and acoustic panels.
One 14 inch riser for the rear 8 feet of the theater and recliner seating for 6 or 7 (depending on costs)
So, I'd guess you're planning a star ceiling in your theatre.
Originally I had planned that but I guess that I am too much of a purist about stars and they don't look real enough for me.
A few more details:
I plan to use my present PJ for the time being (Screenplay 7200) and wait until some of the new generation 1080P PJs come out in the next year or so.
12 inch soffits and a 10 inch soffit island for the PJ.
6 zone Grafik Eye GRX-3506 controlling: Front floor, Front seating, Rear seating, Two colors of soffit ropes, Embryten LED wall wash cans. Also Embryten LED step lights for entry and riser steps.
Entry to front as yet unframed will have a 5 foot entry alcove
Equipment control by Niles IR unit into electronics bay. I have an RF Pronto now but recently it has started acting funky and it seems to be some sort of interference from my neighbors so I elected to go all IR.
The AC folks came up with a neat buried AC duct (the cap in the floor is the output, temp cover) that I had not seen before. The outer is 16 inches and there is an inner 12 inch duct that is perforated. Between them is loose fibreglass. Kinda like a big 12 foot long muffler.
All equipment except PJ and speakers on open racks that I can walk around. No more wire games!
The Electronics Bay will also contain my PCs (my office backs up to it) and routers, etc. as well as a HTPC that I can feed to the theater, Billiards room, or breakfast area. I am doing this in lieu of the spendy and here today gone tomorrow home media standalones.
I plan to finish the billiards room first (easier and the table is already at the distributor) and then the HT. Maybe a nice PJ will show up by then if I am lucky. In any case, I hope to finish the HT by XMas...
I am really curious as to how the ICF does with sound. 4-6 inches of concrete bonded to 5 inches of foam oughta be great but we shall see....
