Trace back the driver's impedance from the crossover schematic.

I'd like to know the impedances of these drivers: HT, MT, and TT.

Can we trace back the impedances of the drivers from the crossover schematic?

Thanks for the help.

A (preferably true RMS) multimeter, a signal generator, a resistor, a switch and a variable resistor allow you to build a ‘Wien bridge’. That way you can measure your own impedance at various frequencies. I used to do this in the pre-pc era.

Otherwise, just get a dual channel audio interface, some resistors and LIMP (ARTA) to measure yourself with your pc. It’s not really hard to learn. Just my 2 ct.
