A subwoofer is a special type of loudspeaker designed to produce low-frequency sounds, typically below 200 Hz. These deep bass sounds are essential for creating a rich audio experience in music, movies, and games. Subwoofers enhance the overall sound quality by adding depth and power, making you feel the beat of a song or the rumble of an explosion in a film. Subwoofers can be found in various audio systems, from home theaters to car audio setups. They come in different sizes and designs, including active and passive models. An active subwoofer has a built-in amplifier, while a passive subwoofer requires an external amplifier to function.
