That reminds me of something, PLB
By the way the filter target I used above (red) was 24dB/oct and it would have been possible for a range of others.
Aiming for the lowest reaching notch effect, first order filter and the freedom to adjust any component, the 11µF cap was always the correct value regardless of the notch frequency. When I found the lowest notch frequency that worked properly, it turned out to be the tweeter's resonance frequency. Coincidence? Maybe...but the plot of impedance with just the notch is interesting.
