Corner loading maximally excites the room modes, so a stereo pair creates strong peaks/dips in the response that aren't easily resolved in a typical rectangular room.

GM, thank you. I appreciate your answers.

I looked at the 212 specs at GPA. Does that massive frequency dip/peak between 10 and 15khz mean that it really needs a separate tweeter? Or is it something that a good crossover could deal with instead? (Not sure I can hear 15khz very well anymore anyway. One of my TVs 15khz is quite audible to the kids, but not so much to me.)
