There are lots of different complexities of models and many different crossovers shown in that document. Some model the loudspeaker as a simple series coil and resistor, others go a step further and model the mechanical resonance with a tank circuit. I'm sure with your familiarity with Spice you can tell what is what, it just takes a minute to follow it through.
