Yeah, Octave RTA is what I use. Very handy indeed.
Try it at a live concert and see how little HF you're getting! The 32C is just about right in that respect.
I like that scheme of running the LF full range. Of course, the response of the LF driver will then suggest an appropriate crossover point. 414s play up to 6k+ pretty well, for example giving a lot of flexibility and requiring a low pass network if you want to run the horn low.
I had good results with a high first order crossover on 802s and a 32 filling in above the 414s.
I don't know anything about that JBL woofer. Figure out how high it plays on its own, a very useful data point.
When I get some time I'll play some wide spectrum music (Earth, Wind, & Fire perhaps)
and get a sense of how the speakers play
Poking around the Lansing site I found these specs for that 2214 Woofer:
"Here's the 2214H's T/S parameters (L100T), etc, and the 128H-1 used on the 4412(A)"
