Hi Wayne,
Do you have a Spice file for your Vifa DX tweeter that I can use to model a x-over(?). (And one for Beyma CP-21/JBL-clone?)
Best Regards

Illuminati (33rd Degree)

The DX25 voice coil has 2.75Ω resistance and 0.03mH inductance. It's mechanical resonance can be simulated with LCR values of 2.4mH, 24μF and 13Ω. A Spice model is shown below:
! tweeter virtual circuit (DX25)
! voice coil reactance
R1 2 3 2.75
L1 3 4 0.03mH
! mechanical reactance
L2 4 0 2.4mH
C2 4 0 24uF
R2 4 0 13
