X-over point vs speaker impedance

If I have a passive x-over designed to HP an 8 Ohm tweeter at 3.0kHz 12db/Oct, at what freq will it HP if I use a 4 Ohm tweeter?

I know on a simple 6db/first order crossover, the frequency will be either an octave up or down, I forget which. A twelve db might be the same or more complicated, not sure.

If you know the values of the caps and coils you could plug the numbers into a crossover program, that would tell you... used to be free box programs on the web.. perhaps there are crossover programs as well.
