Gentlemen, I have a 150 Hz tractrix horn mounted with a BC 8PL21 driver. The backchamber is suitably small I believe.
This is the impedance plot of the system:

I would like to have your opinion on this plot. The main peak is where I want it. However, there is a secondary resonance at 55 Hz that is a bit worrying. Can anybody explain this behavior?
Best
Kris
