Crossover Network

I see that the Ls and Cs in the cross over are working into the impedance of the speaker so I would like the impedance in the model to be some what close.

With the Zobel networks then the crossover networks are loaded correctly.

eTech,
Where did you get "tweeter.lib"?
Please attach you spice and lib files. I would like to give it a go.
You can plot V(tweeter)+V(mid)+V(wolf) to get the total frequency response.
Ron,

----edited----
I don't know the frequency response of the raw speakers so we really don't know the total frequency response of the system.

Here is the frequency response of a Dayton 385-8. There is a nasty bump at 1.2khz. Hopefully the cross over network will role that off.
The frequency response below 200hz will depend greatly on the enclosure.

AND
Here is the impedance of this speaker. I don't know if the SPICE model takes into account the inductive effect above 200hz.
