Thanks guys. This is what the room will look like (kinda of, based on my poor Paint capabilities) when finished. We are using all the current substantial Realtrap inventory, the GIK art panels, and then adding a customized treatment system designed by Jeffrey Hedback of Hedback Design (same great acoustic engineer/consultant who did Art's room).
It will include custom corner traps (triangular floor to ceiling, front corners) being installed this Friday, a 400 lb helmholtz resonator wall (already installed two weeks ago and making HUGE sonic improvements in cleaning up the room noise, etc) and a set of wood slat diffusors that will create a huge hanging ceiling cloud (uses clever acoustically inert hangers and foam above slats) and two wall diffusor systems. Above the wall diffusors will be tetrahedral acoustic treatments. My video screen hangs off the non-moving portion of the front resonator wall. I had ideas about instead doing an automated pulldown screen forward of this, to hide the center channel during viewing, but this setup currently fits me eye real well and sounds great so far (and reduces expenses, of course, by using the current Stewart Studiotek 130 screen).
