Chrisbee... I hear you man. I've had the IB installed since December, though, so I've been enjoying it for awhile. Now it's time to make it even better. I have had the vertical and rear wall bass traps in for a couple months and they definitely help. I especially noticed the difference when I took them down to paint the room. There was a major difference. I lined the side walls with the 8# mineral wool just to see how it would affect stereo playback... and I noticed a surprising amount of increased clarity. I was rather doubtful going in, but pleasantly surprized. I would imagine first point reflections will do even better with 3# compressed fiberglass (better high frequency absorption when not hit straight on) than the 8# material. We'll see. The nice thing for me is nobody else I know is an audiophile by any standard... which means I'll optomize the sound for my seat and nobody will notice the difference in theirs
