A subwoofer is a loudspeaker designed to reproduce low-pitched audio frequencies, typically below 200 Hz for consumer subwoofers, below 100 Hz for professional subwoofers, and below 80 Hz in THX-certified systems. Subwoofers are used to augment the low-frequency range of loudspeakers covering higher frequencies and are therefore not used on their own.
Subwoofers are often used in home audio systems, car audio systems, and professional sound reinforcement systems. In home audio systems, subwoofers are used to enhance the bass response of music and movies. In car audio systems, subwoofers are used to provide a more powerful and immersive bass experience. In professional sound reinforcement systems, subwoofers are used to provide low-frequency support for live music and DJ performances.
