A subwoofer is a type of loudspeaker designed specifically to reproduce low-frequency sounds, typically below 200 Hz. These deep bass sounds enhance the audio experience in music, movies, and games, making them feel more immersive. Subwoofers are often used in home theater systems and car audio setups to deliver powerful bass that regular speakers may struggle to produce. Subwoofers come in various sizes and designs, including powered and passive models. A powered subwoofer has a built-in amplifier, while a passive subwoofer requires an external amplifier. Many people enjoy adding a subwoofer to their audio systems to feel the rumble of explosions in action movies or the thump of bass in their favorite songs.
