Hi Wid,
Not from late 2002. The crossover changes in the M80, which resulted in a more linear and audibly smoother upper-midrange response, were implemented in mid-2003, after a series of double-blind listening comparisons of an M80 "A" version (the original) and the modified "B" version. The "B" version won the tests by a slight but statistically significant margin and the changes were implemented immediately in on-going production of the M80s.

Thanks Alan. That pretty much clears that up.

So only the M80s changed slightly....what about the M60ti from mid 2003 and the new V2? Did that change as well?

Hi ereed,
I liked the M60 a lot from the time I first auditioned the entire Axiom line in 2002 and did not suggest any changes to the M60.
I believe the M60's tonal balance has remained essentially unchanged, however, I once asked Ian last year if he'd made any changes to the M60 and he replied, "Oh, yeah," but didn't elaborate. I'll question him more closely and report back.
No audible changes have been made to the M22s. We did try a different configuration of the tweeter and midrange drivers last fall for a listening test, but the current array won the contest and stayed the same.

Nah, they put the tweeter on the back and the port on the top. Revolutionary, I tells you.

Thanks Alan, Now I can say definitively that my m22ti's have the same sonic characteristics as the currently selling model. Quote:

Hi JohnK,
Yes, Ian was curious to try the well-known D'Appolito array, so he had some M22s built with the MTM (Mary Tyler Moore?) configuration.
He didn't tell me what I was going to be listening to--he never does, because he wants the listening comparisons to be entirely unbiased, which is the only way to make such judgments--and there was really no significant difference between the two. I seem to recall a slight preference for the non-D'Appolito but the scores were so close, it just was not significant.

Randy,
Absolutely. We've played around in the lab with the M22's crossover to remove a slight non-linearity in the midrange, and it measured smoother in the anechoic chamber, but when the double-blind listening comparison was set up, we all preferred the existing M22's crossover! So nothing was changed. It was an interesting exercise in design theory and real-world listening.
