measurement evaluation

Hi
I have a strange peek in my measurements (nearfield cone and port it also show in the impedance) at 200Hz any idea what it is?
regards
Fredrik

And yes the baffle is 200 mm wide.

this type of discontinuity is generally the result of a mechanical or acoustical resonance, or a leak.
In the absence of other indication (box type, speaker) it's difficult to be more precise.

It looks like a port resonance. Can you share the details of the driver (T/S) and box/port parameters?
