I am talking about aligning phase vs. aligning the drivers for time coherence. and I don't remember what the OEM polarity should be so I suggested to flip it so that you hear it in both polarities. IIRC the staggered positioning from the maggie manual requires flipping the polarity to compensate for some 60-120 deg phase difference turning into 180 deg at some portion of the XO range between 250hz and 400 hz and thus a big dip in FR at a critical portion of the F spectrum. That since the 2'ish ft offset of the bass in back introduces another 1/4 wave of phase.
That as opposed to time alignment (bass ahead) where you are reducing phase by that same 1/4 wave. In this case you risk having a lump in the FR at the lower mids or a suckout when polarity is reversed.
