A 2-way speaker works by utilizing a crossover network to split the audio signal into separate frequency ranges. The crossover directs the low-frequency signals to the woofer and the high-frequency signals to the tweeter. This division of labor allows each component to focus on its respective frequency range, resulting in clearer and more detailed audio reproduction. The woofer, typically larger in size, is designed to move air and produce deeper bass tones, while the smaller tweeter is responsible for delivering crisp treble sounds. When combined, these two components work in harmony to deliver a well-rounded and immersive listening experience in the car.
