I'm configuring a home theater room with dimensions of 13' x 15' with a 9.5' ceiling height at the wall (it slopes up from there in a "V"). From what I've read in this thread, your horizontal masking system requires an addition 5.5" (per side). For a 100" wide screen, will the total width of the screen, frame, and mask be 100+2*5.5=111"? If so, that would leave me 22.5" on each side for my speakers which are 18" wide.
Current eye position is 14'. With a 2.35:1 screen, the height will be 42.6", so the minimum seating distance is ~7.1'.
I plan on using a 16:9 projector with a Panamorph UH480 (with MTH1 Sled). Will a Panasonic AE3000 projector or a JVC RS20 projector work for this configuration?
Finally, could you PM me a price for your 100" 2.35:1 SmX screen (curved AND flat) with horizontal masking?
