Very different that hasn’t been discussed, is the active has better sharper active (-24db) xover slopes compared to the passives (12db-18db), which means the drivers are working in a better part of their frequency range, should equal less distortions. Not because of the muti amps, but because of the active xover. But then there's the sound of the active xovers to consider with all their electronics now in the signal path.
