It is most important to "phase align" or "phase correct" 2nd order crossovers because of the phase change.The phase relation is independent of the slope or Q of the filter. Note also that while we use 2nd order and 12db interchangeably, only a Butterworth (Q=sqrt of 2) is down 12db at one octave. The L-R as shown here is down ~13.7 db at the octave reflecting its softer slope.
I may be an egoist but at least I don't talk about other people.
