Hello Lee,
There were no changes to the M22 v2's crossover from the original M22ti. When I joined Axiom and began listening tests to the entire Axiom line in 2002, the M22ti was one of the speakers that I said, "Don't change a thing; it's sonic performance is lovely." The v2 designation was because we changed mechanical things like the binding posts, the method of grille attachment, etc.
Some other models in the Axiom line did have changes in the crossovers, including the original M80ti, the VP100 and a couple of others. The M40ti was discontinued and a small mini-speaker as well.
Regards,
