Wow that's pretty sweet! I'm scouring the internet for the right solution to treating the room that I'm having built. That looks like a TON of treatment for such a small room. I'll bet it sounds killer! My room is 18x20 and after seeing the costs of shipping for Rockwul or Corning panels, I'm thinking I'll make some 4x2's and use Rockwul from Home Depot. There's a couple of how to's on the web. I was set to order foam bass traps tonight from ATS but their shipping cost stopped me. I found a similar product on Reverb that's a bit more expensive but the shipping is cheap. There's about a $30 difference and there wasn't much info on the Reverb page. I think I'm looking at about $130 just for two packs of 2each which only treats two corners. I'm probably just gun shy because I've dropped about $1200 today on stuff for the room (TV, couch, mixer, big knob, 2nd DXR10....).
The sketch up drawings are slick!
