Hey thanks guys (and the e-mailed tip too),
This has turned out to be harder than I thought, mostly cuz I'm trying to do it cheap (I may be moving soon, who knows what the next HT room will be like).
FWIW my temporary screen uses a wood frame, and the flattest side of knit white speaker cloth ($7 a YARD, Parts Express), with a bed sheet backing stretched tight. Works pretty well actually. Very low gain, but excellent blacks, and totally non-visible pixels. A very smooth, if somewhat muted image. If you want something accoustically transparent to get a feel for what size screen to get, you can't do much better IMO. As others have said, a bed sheet alone is HORRIBLE.
So far I'd say:Stewart "Studio Tek"
... brightest, and best colors, but poorest blacks (no surprise I guess) with some glare and lots of "sparklies". Given it's heavy soft vinyl backing the most disruptive sonically (subjective opinion). Cost, in the "GMAFB" category.Vutec Transparent
...very coarse with heavy pixel accentuation. Similar to the Draper with its woven screen material. Might work well with CRT and a BIG screen but a bust with small, close LCD viewing. Cost, cheap < $10/ft2.Draper AT 1200
nice image, not as bright as the Stewart but better blacks. A good compromise all 'round. Much tighter weave and smoother finish than the Vutec but still a "woven" sceen like material, something like mosquito netting. Cost, who knows? Can't find anyone to sell fabric alone.DaLite "Audio Vision"
. Samples en route hopefully. Said to be matte white perforated vinyl more like the Stewart than the Draper/Vutec materials. Cost, very reasonable, far under $10/ft2.
Will post my findings when I get done buying something and mounting.
