My 103" Spandex Screen Build
To begin, I’d like to thank member Ftoast for his kind assistance and patience in helping me figure out which screen type to use, and tips on the build process. I also received a great deal of help from previous build write-ups, and other members here on AVS to whom I’m grateful.
1. Apartment Living room – 25’ wall.
2. The room is light controlled to a degree, but mostly just a dimly lit - mellow atmosphere.
3. The Benq HT2150ST (short throw) projector will be used for all TV and movies, Blu-ray player, PC, HDTV tuner, and a Roku. It will be on quite a bit.
4. Screen Size: 103” diagonal – 95” x 55” outside dimensions.
I chose the Spandex White and Black layer build because of Acoustic Transparency, Low Gain, and it was highly recommended.
In order to get the largest screen possible on this wall (103”), I needed to completely cover my front (3) Rodgers Sound speakers. Anything smaller would not be an upgrade over my previous 70” Sharp HDTV. Go big or not at all! To have an acoustically transparent screen for under $ 300.00 in materials is pretty darn good. In addition, the low gain light properties of the matt Spandex naturally prevents “hot spotting” due to the nature of a “short throw” of the projector – Bright and Close is not such a great thing on a higher gain screen, or so I’m told.
Meat and Potatoes
3 yards Millsikin Matt White Spandex
3 yards Millsikin Matt Black Spandex - Both from Spandex World in NY
2-1/2” x ½” Pine
Half round trim – to elevate the screen off the front of frame
Screen Tight - 1-1/2 x 8’, and 1/16”
Spline cut into 4” pieces
Misc. screws and hardware for corners and center braces
3” - Projector Felt Tape Border - Vibrancy Enhancing by ConClarity
Again, this is a 103” diagonal screen. I made an initial mistake by ordering only 2 yards of each. That would not have worked. The idea is to pull the Spandex tight enough to get rid of the sags and get it taught -not wavy. But, not too tight as to open up the “pores” and ruin the screen surfaces. 3 yards was the right size for this screen.
Using the Screen Tight and 1/16” Spline worked wonders for me and am very happy I didn’t go the staple gun route. This method makes it is easy to start, move around the perimeter, make adjustments, remove, tighten, etc. Not too pricey either. Don’t forget, you have (2) layers of Spandex to stretch over your frame. It’s interesting because my good buddy, who is a carpenter by trade, suggested this method right off the bat without any knowledge of projector screen builds. Hat’s off to CoolLarr!
Pine Select Wood – I admit to not being a wood project guy and will tell you some of this stuff is pricey. What the heck is this, Titanium? Pine select seemed to hit a budget sweet spot for me. But, be aware to check each piece you buy for straightness, if no good - grab another one.
The finished product surpassed my expectations in every way. The result was well worth the effort and expense, with no regrets choosing this screen and build. The picture quality is stunning, especially at night, and my speakers are behind it for a cleaner look.
