| i'm saying that the 10"s and 12"s have a possibility of causing destructive interference with each other. doesn't always happen to a noticeable degree, but it's happened enough in rigs i've played where the cabs weren't matched that i would never do it.
as for whether you should do the hartkes or the mesa cab, i can't answer that for you, but if it were me i'd probably keep the hartkes, especially if they're hydrives.
