Abstract

This tutorial paper defines the function of a crossover network and then explores methods of meeting this function. For moderately priced two-way loudspeakers, a passive network at about 800-1600 Hz will continue to dominate the designs of the future. However, the use of active filters (electronic crossover networks) and buffer amplifiers offers the most significant means of loudspeaker improvement in the next decade. As one typical factor, crossover frequencies need to be lowered and crossover slopes increased, and the active filter is the only economical method of doing this.
