Wow...I can see why you've renamed this the slippery slope. That was fun to read through, and watch evolve. You're giving me courage to try some of the ideas I'm kicking around for my room. I love the simplicity of your screen wall. Have you considered going acoustically transparent, and placing the speakers behind the screen? That way you can get them away from the wall, and improve the overall imaging. Where's your center, by the way? Is it below the screen?
