So would it be best to calculate your main viewing/listening position first then work backwards to speaker placement? Based on a 120" diagonal screen it looks like the viewing position would be roughly 12 ft at 1.15x but for a 16x9 120" screen the calculation for best viewing is 15 feet. I guess my question would be would everyone with similar sized screen have the same viewing/listening position regardless of room length/width? Or do you have to account for the room size first?
I always consider room size and listener location first based on modes. Then speakers. Then screen. It is way easier with an AT screen because sightlines for off axis viewers arent an issue if LCR is behind.
I usually draft the room with furniture to ensure it “works” as a living space wise before I submit for review.
Admittedly, I skip this drafting step if the owner doesnt need reassurance. Just use math instead.
