I'd use 80Hz for the LCR's and 100Hz for the Axioms (maybe even 120Hz), but try using 80Hz or even 60Hz for all of them for the sake of auto-setup then set back to 80Hz & 100Hz afterward. Having the crossovers too high has been a problem for auto-setup. ALso, I'll bring in my SPL meter tomorrow and you can try a manual calibration if you want to.
