Duke,Yeah. Thanks. I really hadn't noticed inappropriate reflections with my array, but that was before I started building the home theater room.
Actually in Jim's paper, one can guage the distance of the nearfield by the length of the lines, in his chart. For me its about 9 feet for the tweeters and much larger for the midranges. its one of the reasons why I keep gradually enlarging the tweeter array(I'm using domes rather than ribbons.)
