Randy and Axiomman,
To elaborate a bit more, the v3 series (M80 and M60) not only had crossovers tweaked but new drivers that required the crossover changes.
Axiomman, to put it another way, the M80ti with the redesigned crossover that appeared in 2003 was being produced for two years with no change in the "ti" designation, until 2005, when we created the v2 designation. Numerous owners of the M80ti purchased after 2002 have emailed us with the serial numbers of their M80s. From that we can check our records to see if their M80 includes the redesigned crossover.
