I want to simulate a 2way crossover network I designed through PSpice and measure impedance, but I don't know how.
You would have to replicate the impedance curve of the drivers
with other modeled circuits as well. To see the crossover behavior.
Be a lot of work.
Crossover design software much easier.
Since impedance data is provided
and also frequency response is provided.
typical learning curve as always
and need ZMA and FRD files for driver
needed. Manufacture can provide these
or make your own with tracing software.
From manufacture datasheet.
Virtuix Cad provides all of this.

It is fairly easy to replicate the impedance curve if you have the T/S parameters of a driver by calculating the following:
- Le and Re
- Ts = 1 / (2π Fs)
- Cp = Ts Qe / Re
- Rp = Re Qm/ Qe
- Lp = Re Ts / Qe
However, still there's still a problem. The acoustic load is not modelled and the impedance curve changes (somewhat) when the driver goes into a box. Even if you somehow manage all that, the SPICE simulations would still show you only the electrical slopes that result.
