I had the opurtunity to test an XP18n on an IMAX screen just to get an idea of how bright our video conferencing system would need to be.
To achieve 10 ft-L with the XP18n, I was guessing that I would need to project on to an area no larger than 200 Square feet which works out to be about 16' X 12'. But to demo that size image, I would need to have been half way up the theater seats which would have been awkward for a presentation. So, I gave the back row a chance thinking to myself, "if I can even see the image, I would be lucky."
Wow! was I ever wrong. I projected a nice and bright image that was 40 feet by 30 feet wide. People, that is 1200 square feet or 1.4 ft-L if it was on a unity gain screen! But it couldn't have been that dark, there is just no way. It appeared much brighter than my UP-1100 which projects in my dark HT room on a 28 square foot screen which is probably somewhere in the low 20 ft-L area.
Anyway, they have to be using some gain, but due to the curved screen surface they can get away with it without any hotspotting and still have holes for the speakers.
bottom line: Does anyone know what screen fabric they use?
The demo went great. I thought we would have to get a double stack of Proxima 9410AV's; but now I know one will be more than enough.
