Another thing to look at is Sallen Key filters. Sallen Key filters provide adjustable crossover frequency, slope and filter Q. It provides an almost unlimited number of parametric EQ functions, from overdamped to underdamped - having a "suck out" or a huge peak at the desired frequency. All these things are adjustable with this kind of circuit.
