I think I understand how to calucate values of L and C to similate mechanical reactance in SPICE.
R of L and C = Zmax/Qms at F(res)

However, looking at your examples of woofer models in the crossover document on your site, it seems to assume that Zmax ~ 10 x Qms for all drivers. This would be correct for the Alpha8, but does not match the specs available for the other drivers. Can you please clarify?

Also, is the R value in the mech reactance model set at Zmax?

thanks,
