That is interesting. I hadn't read that before, but my center channel is about a foot and a half out in front and hanging above the TV aimed down towards my head. And I don't have any trouble what-so-ever with dialog intelligibility. In fact, as I pointed out in another post, I actually turn the center down to zero db's and run the mains at around +3.

Works for me.
