Do you know if that 2.0 gain is before or after microperfing? In other words, is it a 2.0 screen that has holes punched in it (and maybe ends up at 1.5), or is it a 2.5 gain (pure guess) that has holes added and ends up at 2.0? My guess is that the amount of hotspotting would have more to do with the higher number.
CWILSON: I'm not really sure how that works, but my guess is (take that for what it is worth!) that the gain listed (2.0) is that of the final product *after* the holes are added (does anyone here know for sure?). You do notice the holes if you get up close, within 5 feet or so; my first row of seats is at 12 feet so I never notice them. The other thing that I did is that the entire wall behind the screen is painted flat black in order to minimize light reflections. The center channel cabinet is black and I removed the speaker grill/cloth from the center before I set it in place. Some people have mentioned that they have noticed that their screen vibrates a bit when the center is very active, but I have yet to see that with my setup. The front of my center is about 8 inches from the back of the screen.
I will say that I was very nervous about getting this screen because of the high gain; many people told me I would have hot spotting and some people told me not to worry about it. I have not had any hot spotting, so I am very pleased with the results. To be honest, I think the reason why I don't have any hot spotting is due to the fact that I am using a CRT with 7" tubes, the dwin hd700. My guess is that if I used a different projector with larger tubes, then I may have ended up with some hot spotting. It just so happens that given the size of my room, this being my first theater that I built and my budget, this combination of screen/projector, not to mention all of the *other* stuff you need to buy, worked out great for me.
