Different frequencies of sound are directed to different speakers or speakers components through the speaker crossover network. The crossover network of a 2-way speaker separates the sound into highs and lows, with the highs being sent to the tweeter and the lows being sent to the woofer. In 3 way and 4 way speakers, the crossover network is more complex, separating the sound into multiple frequency ranges and directing each range to the appropriate speaker or speaker component.
