My wife kicked my audio equipment and me out of the living room. I thought that it was a pretty good room for listening, about 24' (length) by 12' (width). She thinks it is a pretty good room for watching TV.
Today, I moved into the "den," which is 16' (length) by 12' (width), with eight feet less in length. I placed the speakers three feet from the rear wall (there is a five foot wide opening in the rear wall that leads into another room; the opening is between the speakers but is narrower than the distance between the speakers, which is eight feet), two feet from the side walls, and toed in to face the listener (me). My listening chair is about seven feet from the wall behind it. There is a rug on the floor between the chair and the speakers; otherwise there aren't any room treatments.
I could only listen tonight at a fairly low volume, but I am not accustomed to sitting so close to the speakers. When I sit in the chair, slightly reclined, my ears are only about 6.5' from the speakers. Soundstage is there, but vocals seem to have moved back.
I'll experiment with speaker and seating placement, but I will obviously need to become accustomed to "near(er) field" listening.
