For the last two years I've been using a 115" wilsonart laminate screen with great results. Last summer I did a big speaker upgrade (JTR T12's in front) and decided to go AT. I'm using a benq w6000 with a cavx iii lens so I knew I wanted to stay with a curved screen and go as big as I could. After consulting with mississippiman, I went white over silver from spandex world. Here was the process-




Used spring break to frame out my screen wall to hold speakers. Don't have room for a false wall so that's doubled up 4x4's put together with 6 inch screws and attached to every stud. 50+ screws used but those are big speakers.




Cedar rectangle 1x3, spacers cut with the Aussiebob spreadsheet for curvature, PVC 1x3 cut and attached to make the curve






Covering up this-




And then a basic velvet border attached. End result is this-



I'll post movie pics later. I can tell a big improvement in vocals from bringing the center even with the L/R. I don't have as bright an image as the wilsonart, but calibrating with calman went pretty fast with minimal adjustment. Detail seems greater... Watching sky fall the other night I could see the texture in Bond's tuxedo shirt in the casino which I never noticed before. Overall I'll trade the slight brightness loss for the size increase and sound improvement.

A large, curved spandex screen. Cool!
The reduced gain and increased size should lend a helping hand to the W6000's black level.
After much experimentation I found that white spandex over black gave the best compromise between brightness, black levels and ambient light control for my BenQ W1070.
For the price, the stretchy stuff can't be beat.

Yep...a groundbreaking project as far as employing the use of Spandex.

Also showing tremendous promise and potential for higher lumen, Mega Contrast Projectors using either Lens Memory or A-Lens set-ups.

The superb acoustic transparency aspect is the proverbial icing on the cake.

Could you ask about screen curvature?. What´re the materials?. How do you calculate the angle?.

Thanks !

Sorry I misspoke in the first post it's Aussiebobs screen curve calculator. Here's the link-

Thanks for the compliments. Considering it was my 2nd screen it went together pretty easily. I will say that having an upholstery stapler and and a wife who's into sewing and fabrics were really the things that quickened the process.

It looks like it, but there's about an inch in between speakers and screen and the screen is about four inches in front of the L/R. I finally built my black spandex panels to mask the L/R so now all I have left to do is my 16:9 masking and I'm done.
