Active Crossover Kit for DIY SpeakerBuilders
Filter Schematic
This is a partial schematic of one channel of the crossover. The arrow pointing to the "Bandpass" means that your banpass filterwould be connected here. This is composed of a 4th order highpass and lowpasssection. Therefore, it would require 4 op amps instead of two. This bringsthe total to 9 opamps / channel. 10 *dual* op amps are provided in the kit. This means you will have two opamps left over to experiment with.
