Most of the baxandall results just show existing circuits. Worst of all they do not give information that answers my question.

This pdf is really helpful when it comes to designing narrow-octave equalizers, but I am just looking to do a three band equalizer for now.
For a 3 band equalizer, i simulated a circuit using gyrator band filters that have the following specs:
- Bass: Cutoff frequencies at 10Hz and 400Hz. Center frequency 63hZ.
- Mid: Cutoff frequencies at 400Hz and 5200Hz. Center frequency 1442hZ.
- Treble: Cutoff frequencies at 5200Hz and 30000Hz. Center frequency to be determined.
Do you feel this is a good design, or do you think I should place the center frequencies and cutoffs elsewhere?

There is a three band version of the Baxandall you can find on the LF353 data sheet: http://www.ti.com/lit/ds/symlink/lf353-n.pdf
There was an example with equasions in an old National Applications book, but I haven't been able to track that down.
