Hi There:
For complete analysis check out following books:

1. Audio IC Op-Amp applications by Walt Jung.
2. National Semiconductor "Audio Handbook".

Neither of those links gives equations for the mid control components though,
scaling the components should work...???

the thing about a baxandall stack is that the mids are affected by the relative position of the other two....so there isn't a mid control per se.
