I'd be curious to know how your setup compares to high end offerings on the market from say , for example stuart (st130, firehawk...) Sounds exceedingly simple, inexpensive option. Have you ever done an AB comparison?
Kinda difficult to do a A-B comparison between 2 different 5' x 13' screens in the average HT.
However, anyone who has seen my setup expresses disbelief when I describe the screen construction. Everyone thinks it is a commercial screen.http://webpages.charter.net/tvdias/Screen_small.jpghttp://webpages.charter.net/tvdias/Curtain_small.jpghttp://webpages.charter.net/tvdias/C...open_small.jpg
Note: The bright spots in the lower center of the screen are from reflections of the camera flash off a glass table in the room.
Since I was a professional projectionist in movie theatres for 40 years, I have a pretty good eye (and ear) for imperfections of any kind, and I can honestly say that my current screen is 100% satisfactory in my HT. I think that Don will agree, although there was a healthy amount of doubt in his mind on the day he started it.
Many years ago (~20) when I lived in Colorado, I constructed a frame using the same techniques, except that I used a commercial cinema 1.5 gain lenticular screen fabric (unperfed, however) made by Hurly who manufactures screens for comercial cinema applications. http://www.hurleyscreen.com/index.html
If you think about it, screens really don't need to do much:
1. Provide an even surface with no wrinkles
2. Provide a uniform level of reflectivity.
3. Possibly concentrate that reflectivity in a specific area (if the screen has a gain of <> 1.0.
4. If it's an acoustically transparent screen, allow audio transmission with minimal losses.
Items 2,3 and 4 are primarily a factor of the screen fabric. Only item 1 is significantly influenced by the frame construction.
If you are willing to accept a 1.0 gain screen, then the material and the coating (paint) are not difficult at all. If you want gain then, you probably should get a commercial screen fabric for your screen (unless you paint cars for a living, that is).
