Best mount location for JVC X55R
I recently purchased a X55R and would like to mount it soon as I have it sitting on a box on a sofa table behind the sectional. My room is 22' deep, 9' ceiling, and 139" 2.39 DIY flexi-white 1.1 gain screen. I am planning on building a soffit around the room at around 10" or 12" by 24" or 30". I am going back and forth on ceiling mount or shelf mount and what range would be better. I see the projectorcentral calc says between 15' and 30'. At 15' it is obviously brighter at 21fL according to the calc. At 20' looking around 16 fL. Oh yeah top of screen is 18" from ceiling now. What would you all do?? Thanks!
