Ok here is the link to the speaker load that stereophile use to test their amplifiers.
Stereophile: Home Page.


I am having trouble reproducing the same results of impedance and phase vs frequency that stereophile have published.

I have attached the spice results.
If there is anyone else familiar with LTSPICE that could check this out to confirm whether I have made a mistake or stereophile has made mistake, I would be very greatful.

That you cant do...as the dumps and dips in the low area is very much related to the physical elements of loudspeaker..like portresonances ect ect...

for an electrical circuit model you can just build it in LT-spice...you can model the drivers too.. by adding series resistance to coils..., but things like back EMF can't be accounted for...
