I was looking to purchase an eleven (11) foot diagonal projection screen for our home theater and prices from some of the leading home theater screen companies ran between $4,000 to $5,000.
I had seen that one of the low price leaders for audio/video cables and Cat 5/6 cables Monoprice.com, a company that I have recommended on several of the radio shows that I appeared on, was going to offer home theater projection screen kits so you could build it yourself.
I ordered the eleven foot diagonal projection screen kit which is shipped in one ten foot long carton and contains all the parts needed to build a finished professional looking screen.
This kit was so easy to put together and everything you will need is included even the metal frames are lined with velvet to make this look as professional as you can get. It took less than two hours to install and hang on the wall.
Monoprice.com offers this screen in many sizes to fit most rooms and they even offer motorized version but since we have a dedicated theater room we chose one that hangs on our wall. Picture is to the right of the finish product.
Monoprice.com offers Motorized and Fixed Projection Screens in many different sizes. The fixed frame screen like I used comes in sizes from 106" to 150" (Nine to twelve and a half feet diagonal) and the eleven foot diagonal size projection screen that I installed sells for only $480.50
