I'm thinking of buying gatorboard for my screen. I've noticed the specs say no more than 165 degrees continuous. I'm using a Sony vplhs20 projector. There shouldn't be a screen temp anywhere near 165, correct? On a separate matter, I was thinking of placing my sub out by the seating area or in back rather than under the screen. I was thinking that there would be a better effect there. I have a 19x12 room and a 6.1 system.
