This likely works for the individual.

Granted, I have a completely different setup than yours, and my crossovers are probably widely different.

In my case, the best impact for me was swapping the phase of the passenger side 4" speaker.

I then proceeded to swap the driver side tweeter. This provided some impact, but much less of a noticeable one compared to swapping the passenger side mid.


edit:
Mind you, playing with all these phases still cooks my noodle.

There's a few things to keep in mind, and I still forget about it.
There's the theoretical stuff like;
6 dB/octave = 90 degrees
12 dB/octave = 180 degrees
18 dB/octave = 270 degrees
24 dB/octave = 360 degrees
But that is only for electrical phases.

HOWEVER, how/when the sound hits our ear is another thing entirely, which is sort of like a relative phase.

With active setups, we need to keep BOTH of those types of changes in mind when we sort through EQ, phasing, delay, etc.
