I was referring to the HP, you didn't show new changes in the LP.
The problem with the 18 6 (6 12) is likely phase difference between the tweeter and mids. you can flip the tweeter phase to get it entirely out of phase or go to 18 6 (6 6) again, or 18 6 (12 12) otherwise, you can move the tweeter HP further up to get the phase at the overlap region closer. You can tell better whether it is a phase issue by changing toe in. The Gann charts only show you the on axis equidistant theoretical response. At the 3khz range a 45 deg phase difference (6 vs 12 slopes) is a matter of 1/2" relative distance.
The original III spec (w/35 uF) really takes the mid out too high up and so reduces midbass.
If the stock IIIa alignment is generally better but for the peakiness in the top of the midrange, then you might just want to put a resistor in series with the midrange to lower its relative output. Or increase the resistor on the tweeter - but I think aligning the crossover for better FR is probably a better way.
