Hi asher770,

I had your serial numbers checked at the factory and your M80ti's do not have the upgraded crossover.

I also forgot to mention that during that period of upgrades to the M80ti, over the summer/fall of 2003, there was a change to the tweeter design of the M80s. The combination of the upgraded crossover and improved tweeter produced the smoother and more linear midrange performance that become part of the M80 v2.

Regards,

Alan
