Micah, it's fairly common that tweeters have higher sensitivity than bass drivers and resistors have to be included in the crossover to pad down the tweeters to equalize the bass/treble balance. As Rick pointed out, at one time(upon request)Axiom would furnish an additional resistor(affected both tweeters)to lower the tweeter level a bit more. Apparently the M80 crossover was modified several years ago to among other things reduce the treble level slightly. In any case, Alan has mentioned that the resistor is no longer supplied.
