RE: Using the plain math, what values I am looking at...

Hi
An exact solution requires the amplitude response and impedance curves as data files. Lacking that, using the plot's legend, an approximation would be;
.125 millihenry (1/8 mH)in parallel with 20Mfd polypropylene and in parallel with a 6 Ohm 10 W resistor. Those three parts in parallel are then put in series with your speaker.
If you want to raise the frequency you notch, reduce the C value a little, if you want a deeper notch, increase the R value.
Have fun
Tom
