The thread above is what spawned my interest in doing this, and Chris very much held my hand all the way through the tuning process. So I don't presume to understand it all, however, this was a raw full-range sweep of one channel @1m, with the drivers stacked and wired as recommended, in the custom "wings" discussed through the thread.
We went through a few rounds of EQ tuning per L/R channel, once with HF/Mid/Subs individually, and then three more rounds with them as a single speaker.
