The crossover has no alignment components from what I see. Just a straightforward 2nd order on hipass


Have you measured the impedance of the midrange and AMT at the crossover point? You can then plug the crossover component values into any of the numerous calculators on-line to see if the the mid and high 6 dB points are at the same frequency. If not, there could be a delay built into the crossover that is not obvious.

The xover is only a 2nd order one coil, one cap for each leg.

Fine, but do you know the crossover frequency for each driver? Plus, a simple two pole filter can take on a number of different filter properties. Check out this link and look at the crosover type list.
