...is Fs (resonant frequency) and sensitivity (dB/2.83VAC/1 meter).You want your crossover ca. at ca. 2 times Fs (if the XO's first order).
Stuff like dispersion and all that is rather more esoteric.

Well, if you're shooting for a drop-in replacement into an existing system, the impedance curve also matters in my opinion. Not just the nominal impedance, but also the frequency and magnitude of the impedance peak at the tweeter's resonance - which will have been taken into account in a well-designed crossover.
... not sure how tecnical/fastidious the original poster wanted to be.
For now I dont need to be microsurgeon precise. I love technical though :) Ya might scream if you knew what I was doing to my ears currently. Right now I just need to get what I have in better shape to tide me over for awhile. Info given is more than enough, thanks.
