    Isn't it likely to be more audible if you are listening to a sine wave at the XO frequency, and much more masked if listening to something like music with many frequencies?

      Clarified that further... Some people still think in electrical orders...

      My own 2c to the OP,
      As a phase measurement like Chris suggests, this also is an acoustic measurement, or 'acoustic phase', shown from an FR measurement. 'Electrical phase' of an impedance sweep will not tell you the in or out of the drivers' relative phases or correctly aligned polarities.

        In that case the listening focus is on the crossover overlap region and it's relationship to instruments - ex 440hz A etc

          Phase is 0 to 360 degrees, Polarity is 0 or 180 degrees (or + to + is a outward moving cone, - to + is a inward moving cone)
          With 2nd order filters and poor time alignment, reversing the tweeter polarity might not even create a null. (90 or 270 degrees
          out if phase). Hence manufactures not being able to decide if the tweeters should be connected in reverse polarity or not.
          ​So in this case it may be difficult to "hear" any difference.
