Shown are the overlayed plots of the:
1. Acoustic response of the RD75 in the '3&SQ' baffle.
2. Acoustic response after parametric equalization.
3. Electrical response of the highpass active filter and the 4 sections
of parametric equalization.
The equalized response was obtained after limited optimization time, and
could be improved upon.
