Question Impedance compensation


As I am developing a frequency crossover for the first time I am not sure which deviation of impedance is acceptable.

I enclosed the measured graph: The red line shows the compensated impedance. Blue, without compensation.

Firstly I would like to know if the minimum at 34Hz is a problem. The x-over frequency hould be around 250Hz-300Hz. I tried to modify the LCR, but the bump at 34Hz can not be avoided without causing a problem higher or lower.

Secondly, I damped the resonance of the cabinet. Still there is a slight inconsistency at 170Hz. Does this cause problems?

Thanks for your answer!!!

Kind Regards

Impedance compensation
It looks OK to me. I would not worry about compensating the lower impedance, it only matters around the crossover frequency.

Try to use PNG format for line images in future, it compresses almost as much as JPG but doesn't create the nasty artefacts.
