If we’re talking about the inductance parameter, that’s literally a point along the impedance plot, either at 1 or 10kHz, so the plot is pretty much a necessity for that. But there is a handful of parameters that you can measure without it. I’ve also just uploaded a new video about measuring the T/S parameters. You can find it here: https://youtu.be/XDL4_TIRTu4

Peter,
In Your video T/S Parameters Part 2, you show a calculation for Qms with the variable Z₀. I’m unfamiliar with this and haven’t seen it in any of your other videos. I found another website that referenced Z₀ as the nominal/published impedance of the driver, but you’ve stated elsewhere to not use this value in calculations. Could you please explain what Z₀ is & where I could find or otherwise calculate this value?

Is it possible to obtain them without generating impedance plots in free air and a reference enclosure?
