Many high-fidelity sound systems employ two or more loudspeaker drive units. One, called a woofer, covers the low-frequency range, whereas the other, called a tweeter, covers the high-frequency range. Sometimes, a third unit or squawker is included to cover the midrange. An electrical network, called a crossover network, is used to divide the output energy from the amplifier into the different frequency regions covered by the multiple drive units. Here, we shall concentrate on two-way crossovers as the same rules can be applied when designing loudspeakers with three or more drive units.
