Crossover network

A dividing network that splits a full-spectrum signal into two or more frequency bands and routes them to feed the various components of a speaker system. Passive crossover is a speaker design whereby multiple speakers are in a single enclosure and sound frequencies are separated and sent to be driven by the appropriate speaker.

A two-way biamp monitoring system has a high-frequency loudspeaker (tweeter) and a low-frequency speaker (woofer). A three-way triamp system has a third speaker to reproduce midrange frequencies. Active crossovers divide a line-level output signal from a mixer or other sound source and route the resulting signals to individual amplifiers optimized for the different speaker components.
