Tweeter replacement for Kef 107

It is obvious that I am a novice here, but please excuse me if I
insist: if the tweeter has the appropriate impedance and sensitivity,
and it has the proper frequency range suitable for the cut-point, why
would I need to modify the crossover network?
Because each of those numbers represents a snapshot of a continuously
varying parameter. Impedance at a single frequency does not
characterise the impedance across the spectrum adequately for
crossover design. Similarly, senstivity varies with frequency and the
crossover is designed to account for it. Picking by those single
numbers is insufficient and barely more useful than picking by color.
I recommend you accept KEF's recommendation.
