Hi everyone, I just bought a house and started setting up my home theater in the basement.
I decided that going the paint on screen was my best option and that way I could get the 96" diagonal size I wanted without breaking the bank. Buying the exspencive screen paint was a no go so I did some research including looking at the info on this site and found it to be great. I went with the Bahr "silver screen" paint option. and am thrilled with the results.
This is how it looked at the beginning of the project just after moving in. I built a wall at the back for the projection screen that I would paint on.

Half way done.

Almost finished.

The ceiling is made up of 40 4'x4' "tectum" panels that are used to prevent sound transfer and the right wall is drywall on the lower half and carpet underlay on the top half with insulation behind the entire wall. The basement theater is 15' wide and 35' long and has a 9' ceiling.
I set up my Audio control 3rd octave eq's and ran a pink noise test signal using a 3rd octave spectrum annaliser with mic. and found the room to be very flat in response with just some very minor dips an peaks in the eq's after setting them up properly to flatten the rooms sound.
