Hi Eric,
Beg to differ. Easiest and most accurate is the method I described very briefly. All you need is: play a test tone at the crossover frequency with reversed cable polarity at the speaker, listen for the null as you adjust the phase, correct cable polarity and done.. Don’t want to write a chapter on it so I posted a couple links. "Soundoctor" Barry Ober, tech support at JL Audio sells a disc for $20 with test tones and a variety of other tools for optimizing subwoofers, along with instructions for the why and how of it.
