Hi everyone, with reference to the circuit on attached -- the zobel/ impedance equalization circuit. If we don't know the value of L, Are there any ways to calculate C' without knowing the value of L? I believe this story might be involved in the frequency-domain. Therefore, if we have the data of frequency response, in this case it is a loudspeaker's, such as cut-off frequency or the point where frequency starts to rise, can we use it instead? Please anyone help to explain.

Sorry, I don’t understand answers in that thread well. Can you please help to explain me in detail?
In brief, can we write or convert L into C or f (frequency) form?

Adjust C by measurement until the HF electrical impedance is (approximately) flat and equal to R.
Otherwise, you"ll have to guess by looking at the driver mfr's impedance curve.

What do you know, the reactance at some frequency?without knowing the value of L?
The dependence of the speaker impedance on the frequency is not simple.
It is better to determine the value of C by direct measurement.
Although in most cases such accuracy is not necessary.

What exactly are you trying to do?
Are you trying to understand the impedances involved in the circuit of your first post on a theoretical level?
Are you trying to implement impedance comensation in a real-world loudspeaker?
Somethin else?
