I am planning to get an acoustic screen for my theater and would like opinions on the Da-Lite Audio Vision screen. My first choice would be a Stewart microperf, but the Da-Lite screen is much less expensive. First some general questions about Da-Lite screens. Are they shipped rolled or folded (I have read about screen material arriving with creases in it)? How does the quality of Da-Lite screens compare to other manufacturers such as Stewart, Vu-Tech, and Draper? I was told by a Da-Lite sales associate that the border on the Da-Snap screens is 3". Is this correct? What is the Pro-Trim made of (e.g., black velvet) and does it work well in suppressing overscan or light leakage from projectors? More specifically on the Audio Vision material, how many perforations per inch does it have? What sort of attenuation as a function of frequency response does it have? Is there a noticeable loss of fidelity with placing speakers behind the fabric?
