Well I just joined the EluneVision club. I ordered a 106" fixed frame with the 1.2 gain white screen. I am pairing this with a Planar PD7130 in a small (11'-5" x 13'-4") dedicated room. Floor, ceiling and walls are going to be flat black, but my sound treatment panels are a medium gray. Panels will be used all around the room. Walls are currently a very light gray and the image had plenty of pop on just the wall. The projector is new though. I almost went with a Dalite High Power, but I decided that the HP might be too much for this small room and I wanted a fixed frame, but not the price of a HP fixed frame. I use a 106" High Power in my other room (lots of ambient light) paired with a Marantz VP12S4. I hope I like this screen as much as I like my HP.
I decided to go with black fabric for the sound panels and bass traps on the front wall. Looks much nicer.
