Bi-amped System Crossover Tweaking with TrueRTA

I’m a newbie to software like TrueRTA. The manual for my two-way active crossover says that though crossovers can and should be adjusted by ear, by also using a mic, preamp and software, one can generate graphics that will help get the task done a lot faster.

I can't upload what I want in a permissible format/size, so please see the summed FR and phase responses for the 3 pole filters on p. 8 here http://www.firstwatt.com/pdf/prod_b4_man.pdf . I refer to the 3 pole filters are for clarity. I’ll be hoping to get away with using 2 pole filters at most.

I need to learn how to measure and display the frequency response and phase response of the HP and LP filters-and their summed responses-of the chosen type, slope and Fc of the two crossovers.

Would someone here care to describe their own step by step procedure for doing this-presumably using TrueRTA’s dual trace oscilloscope and an omnidirectional mic and preamp?
