When it comes to assembling the ideal PA system, a quality subwoofer is an essential piece to the puzzle. As its name implies, a “sub” is dedicated to the reproduction of low-pitched audio frequencies known as bass, thus expanding the overall frequency range of a PA system. In addition to bringing earth-shaking bass, a subwoofer also helps to reduce stress from the main speakers, allowing the whole system to run more efficiently. This added productivity can be accomplished by incorporating either a powered or passive subwoofer. A powered subwoofer includes its own amplifier, and in many cases a built in crossover as well – this allows control over the different range of frequencies between the subwoofer and the main speakers. A passive subwoofer requires an external amplifier and crossover, adding another layer of customization and control. Powered or passive, a subwoofer is an excellent way to “bring the bass” and is certain to transform your PA system into an exhilarating concert experience.
