You can't know the crossover frequency without knowing the impedance and frequency response curve of the drivers. a DC resistance measurement is a hint, but not good enough. A 2nd order LP may be a 3rd or 4th order acoustic depending on driver FR, and likewise with the HP filter...
Download LTSpice (or speaker workshop) and model the circuits and look for the -3dB point for each of the lowpass and highpass, when terminated by a resistor. That's the best that can be done with the info provided.
