Got my 130 inch Soundmax4 AT screen today .. shipped from China and delivered today.
Fedex was its usual not too efficient self and my package was stuck in Japan for over a week - no fault of Lee from XYscreen, just Fedex being Fedex.
The screen was a breeze to setup. A few screws and about 30 springs to stretch the screen.
The screen material itself is quite stiff and the weave is very tight. My initial impression is as follow:
Video: Great video quality. My seat is ~9 ft from the screen and there are no artifacts whatsoever. I watched a few scenes from Interstellar, Bladerunner 2049, Avengers, Planet Earth ... and everything was displayed with fantastic details and colors.
Audio: There is some attenuation in the higher frequency - enough that I can make out that I need to run ARC on my MRX720 again. Also I tested it late in the night when I could not really crank up the volume. As of now I believe that with light EQ audio performance will be close to the original.
Question for owners of AT screen: If my wall behind the screen is all triple black velvet, do I still need to attach the black backing, or can I get away with not applying it. My hunch is that the black backing will cause further attenuation of the highs. Thoughts?
