Thinking about 150" Spandex screen

I'm figuring out my room layout, but leaning towards the one in the attached thumbnail. I'll be using an Epson 5040UB projector mounted at a distance from which it can project a 150" picture. That allows for 2' between the screen surface and the wall for the frame and speakers.

When using the black and white layered Spandex, do I need to worry about reflected light getting in from the rear? The windows will be light-controlled, so I'm thinking of room reflections getting in from the side and top. I will most likely be painting the room a dark color with a neutral grey ceiling and carpet.

I see white Spandex in 120" widths, but not black. Do I just need to look at more suppliers, or can you get away with sloppier stretching or overlapping with the black layer?

Is this a 16:9 or 2.39:1 ?


Throw Distance? Should be no more than 15' -3" from the "Screen" (not wall)


The result will be 25 foot lambert


You may want to place the PJ back inside the Hallway. ( that would be cool )


Have you settled on aFrame Plan?



With just the right Window Masking Curtains and suppressed colors on the Wall, "rear lighting" behind the Screen. If this is a AT applications, it would be good to know what exactly your speaker plans.


Have you determined how your going to hold the Screen in place?


Give us some Rope.

I was thinking 16:9, since that's the format of the projector.

You guessed it! I calculated the max screen size at just over 150" with room behind the screen and the projector in the hall with the lens in-line with the rear walls.

You posted a 150" 16:9 plan in another thread that looked simple enough. My current 120" non-AT screen is painted WO cloth on a modular aluminum frame, but I'm handy with wood, too, and need an excuse to buy more tools.

I'm installing blinds that do a pretty good job at blocking light, and can add drapes if I need to make it absolute, though for the windows behind the screen, any light leakage might serve well as back-lighting. I'm thinking about a dark blue for the walls and a neutral grey for the ceiling and carpet.

I'm still rocking my SVS 16-46 PC subwoofer and Swan Diva 5.1/C3/R3/2.1 7.1 speaker setup from almost 20 years ago. I'm looking around at DIY speaker options for the Atmos speakers and possibly to replace the Swans (see "excuse to buy more tools" above).

That's part of why I was concerned about whether the back of the screen needs to be sealed off to exclude reflections. My plan (which hasn't had a lot of thought put into it, to be honest) is to have two vertical posts (wood or a pair of compression fit, telescoping shelf supports I have from some Ikea utility shelves) upon which I would hang the screen. I'd line the posts up with a pair of the vertical braces in the screen frame.

Ok...again I will review you post and reply in depth later today.

Such a Screen is not really heavy, so if the distance from the Wall is not too great, it can be hung onto protruding support at each side, or if upright supports are used, simple Black Out Panels can be made to encapsulate the screen.



I have some good suggestions on hanging the screen, so keep tuned.
