Hello Mickey,
I've never seen a home installation of a perforated screen. You can check them out at www.stewartfilm.com or find the web site for Da-Lite screens. Check out www.projectorcentral.com as well; there may be info there.
I'm told that even with a perf screen, there are acoustical issues because the screen is not as acoustically transparent as the grill material on speakers, so it introduces reflections that compromise dispersion and liinearity. I've not done tests with these screens so I can't comment, but I've been told that you still have to equalize the center even if you use a perf screen.
Regards,
