What is the function of a crossover in audio systems?

The function of a crossover in audio systems is to divide frequencies into separate outputs. This is crucial for ensuring that different types of speakers, such as woofers, midrange drivers, and tweeters, receive the appropriate frequency ranges they are designed to handle. For example, a crossover will direct low frequencies to the subwoofer, mid frequencies to the midrange speaker, and high frequencies to the tweeter. This division allows each speaker to perform optimally, improving the overall sound quality and clarity of the audio output. Proper frequency management helps prevent distortion that can occur when a speaker is asked to reproduce sounds outside its optimal range. This makes the use of a crossover an essential component in designing an effective sound system.
