measuring tweeter parameters?

[synergy]

hi guys forgive me if i'm seeming stupid with this and if this has been a subject before and i've missed it

i've got some old pioneer 2-ways that came with my all-in-one stereo 12yrs ago (the stereo got stolen but they left me with the speakers - pleased about that the stereo didn't work!)

anyways i'm sick to the back teeth of them sounding like a wet fart in a paper bag from half a mile away and figure a new box and crossover would help

i'm ok with measuring the woofers parameters but i'm unsure about the tweeter

is it essentially the same tests as with the woofer?
anything i should know about before i go ahead? (bar not putting 20Hz through them of course!)
