A loudspeaker system is a device that converts an electrical audio signal into sound waves that can be heard by listeners. It typically consists of one or more loudspeakers and an amplifier, and may also include other components such as crossovers, equalizers, and limiting circuits. Loudspeaker systems are used in a variety of settings, including live music performances, public address systems, and home theaters. They can be classified according to the number of drivers (e.g., single-driver, two-way, three-way), the type of enclosure (e.g., sealed, ported, horn-loaded), and the intended application (e.g., full-range, mid-range, subwoofer). The performance of a loudspeaker system depends on a number of factors, including the quality of the components, the design of the enclosure, and the characteristics of the listening environment.
