From Thiele Small parameters to equivalent circuit

[pipizanzibar]

I'm struggling with the thiele small parameters of the drivers and try to simulate them on LTSpice, but I'm not sure about how I can calculate the electric equivalent circuit impedances starting from them. I googled around and there are several persons sustaining several theories, which approximations do you use in your sims?

Explain "struggling"... which models did you use and know of?

This was one of them:

I tried some different theories about converting TS parameters to an equivalent circuit but none of them seem to be reliable enough so far

Do you mean that measured impedance is different a lot than simulated one? Or something else?

A spice model for some dayton speakers with a short explanation of parameters and calculations. It may give you a clue on how to enter your new parameters and edit a model to fit your speaker.
