Yep, tweeters at ear level. I think if you look at the measured frequency response curves, you'll see that the higher frequencies for the M3ti are shelved down while the higher frequencies for the M2ti are shelved up and the the M22ti has a peak at 4KHz. This may explain my results.

I really tried to like the M22ti because I know they are supposed to be better speakers, but whenever I switched back to the M3ti it was a welcome relief from the "analytical" sound of the other speakers.

My point is that you have to consider the listening room when choosing speakers. The M2ti and M22ti may not be the best choice for smaller rooms.
