About time I build some new crossovers from my 604C's that have been reconed by GPA. They are 16 ohm. Which of the Markwart crossovers would be the best fit? The 604B Phase Correct Crossover with MF EQ or the 604-16X Phase Correct Crossover. This is all new and I'm slightly confused.

Thanks for any help to clear up my confusion.
