Hi,
Excellent analysis, Ian. And to respond to Anonymous about my tests with the M22ti used on its side as a center channel, Ian is perfectly correct in saying that the off-axis response to the left and right would be uneven.
I should have said that in my home theater setup, which is arrayed across the diagonal dimension of my living room, I can't check the off-axis response of an M22ti to the left (from the listening position), only to the right. For that reason, I laid the M22ti on its side on top of my TV monitor with the tweeter to the right side, so its off-axis performance in that direction remained excellent.
Regards,
