Speaker and Crossover Spice Models?

I am trying to better understand some of the more complex passive
crossovers I have seen with multiple poles and figured Spice (Orcad 9.x)
to the rescue.

Wondering if anyone has a collection of speaker and crossover PSPICE
models that they wouldn't mind sharing. I figured I would model my stuff
on both JBL and Eminence drivers and crossovers.

If anyone has any OrCAD Spice models for these that they are willing to
share I would be greatly appreciative.

Thought I saw some loud speaker stuff in the LTSpice forum on Yahoo
Groups, but I'm not finding it now. However, a Google search for
"loud speaker spice model" or the like will get you lots of hits, and
a question on the LTSpice forum is very likely to get some replies.

I suspect it will also be very helpful to look up some articles on
passive crossovers that go into the reasons they were designed the way
they were. Just analyzing them will likely leave you with a lack of
understanding of the whys.

Cheers,
Tom

Well that is not to say I haven't done my share of homework, research
and such. I also have found some good links on loud speaker design with
spice. The issue is that 99.9% of everything out there is way over
simplistic. They all tend to be about basic crossover models. Yet if you
take apart a JBL crossover you see they added all kinds of extra poles
and tweaks. What is even more interesting is looking at how they tweaked
say and SR series crossover from the original to the A to the X versions
in few cases where they didn't also tweak the driver.
I know in a nutshell what they were doing, but to see the whole picture
it is nice to model it.
I have yet to find any crossover resource (or commercially available
crossover) that takes it to the level of a typical professional PA
speakers crossover.

My question was simply if anyone had the models so I don't have to hand
make them and figure out all the parameters for common drivers and such.
