Hello, looking to build a screen that will be audio transparent. I am looking into the POLYSILK screen material. Another member used this with foil backing. Any ideas or setups that work would be great. Thanks for the help!

I made a screen with DAZIAN polysilk, and the backing was a black sheet (with a 1" gap between). Sound passed through alright, but the image was too dark for a low lumen projector. A very high lumen projector would have been OK. I am now going to have the center speaker on the floor and use blackout cloth.
