I've decided to go in a very different direction with my screen. Having weighed the pluses and minuses of high power screens, of grey screens, and of having the speakers behind the screen, I've decided that, even if I give up a little image performance, I want an AT screen. The first thing that had be thinking about this was my talks with a certain person involved in the THX standards, as well as realizing that THX required an AT screen. I also have always felt that non-AT screens did not allow a seamless sound image to match the video. Then I read the Japanese article which Dr. Geddes had mentioned, which talks about a woven fabric screen as the optimal choice. Dr. Geddes interpretation of that article was a low thread count bead sheet. While bed sheets are often laughed at around here as a cheap skate option, not a real option, the reality seems that it does fit well with the articles findings, and conceptually, is pretty similar to the better woven options out there. I know some are Solar screen, but some are clearly fabric.
This brings me to today. A bed sheet sure is an awfully cheap option, and really, poly-cotton blend woven fabrics with similar properties to those sold by major manufacturers may be available as well. I've collected as many samples as I can of the available AT screens which fit my requirements (woven). I've also purchased samples of various types of fabrics which appear to be similar to the textile fabric options, rather than poly solar shade materials. I'm waiting to hear from the Screen Excellence on getting samples of their materials. Not just because I'm curious to see what they are like up close, but also because they may end up being the best option.
My point with this post is that I intend to compare them, and take as many measurements as I have the ability to do. my video measurements are limited, but my audio measurements are extensive. My reference will be the bed sheet. If acoustically they can't even beat the 12 dollar bed sheet, then they sure better kick it's tush in the video department. I plan on measuring the materials effect on color balance, make comparisons for gain against known samples, and take on and off axis acoustic measurements.
I can post these results if there are people interested in options for AT screens with Independent testing. While I have a feeling that some will find this ludicrous, there are some experienced HT installers and researchers who have indicated that, basically, if you want both the best acoustically transparent screen and image quality, nothing beats the value of a bed sheet. Let's find out if spending more does get you more, and how much more it gets you. I'm very open to suggestions on what to test and how to test it. I'm far more experienced in the audio world than the video world, and my knowledge and ability to test acoustics will be, for now, far more advanced.
