Impedance graph

[eemit738]

Hello. I shall be grateful if you could confirm whether the impedance graphs are normal or I am missing something.

I am trying to measure the Thiele parameter of a small woofer but the parameters do not seem correct.

i had to uninstall the newer version V5.20.4 to install version v5.20.1 as i was getting an error " Measurement input should be much lower than the reference input for the short circuit calibration but it is not - the measurement peak is -13.1 dBFS, the reference peak is -13.1 dBFS. "

Please help.

Thank you

A better approach to error messages is to fix the cause rather than install an earlier version that doesn't have them. The message is there to help you. Having the same level on the measurement input, which is shorted to ground, and the reference input, which is connected to the output, should not be possible in a valid setup. A possible cause is an input which is mono, or configured as mono, instead of stereo.
