Well, no pictures to share, I forgot the camera, but this weekend was a fantastic demo in how assumedly small changes in room treatment can make HUGE differences in sound quality. In this case a solid vertical board, 1'x6' (?) at 45 degrees across the corner in each corner behind the speakers and an 18" (?) in diameter by 4' soft absorber in front of those, equalized bass response. I.E. the deep base was only audible within a few feet of the speaker before, afterward the deep bass was audible in the listening position farther away from the speakers. The difference was anything BUT subtle. Kudos to Craig for coming up with the fix.
