I needed a big 2.35:1 anamorphic size screen for my theater, and it had to be acoustically transparent, because I plan on putting speakers behind the screen. So I looked on avs forums and watched other youtube videos and decided to build a 120" acoustically transparent screen out of spandex. That's right spandex. And It is awesome! In this video I show how to build a spandex screen yourself and why you may want to do it too. I show the build process and the materials used in the project. In total I think I spent $130-150 and could probably have done it cheaper. This price sure beats over $1,000 for a comparable screen.
