Don't have any graphs to post, which is why I keep repeating that folks try it for themselves rather than take my word for it. At least then you'll understand why you got the same response in this thread as you did in the AVS thread you started.

BTW, it was at least 6 years ago when this was demonstrated to me. I had recently gotten the room correction upgrade to my MC-12, when an acoustician friend tried to convince me that I should be running my two subs in dual-mono rather than stereo (when set to dual-mono, the Lex equalizes both subs together). I remained skeptical until he brought over his measuring kit and an outboard equalizer and proved me wrong.
