A subwoofer is a specialized speaker designed to reproduce low-frequency sounds, typically below 200 Hz. It enhances the audio experience by delivering deep bass, making music, movies, and games more immersive. Subwoofers are commonly used in home theater systems, car audio setups, and professional sound systems. These speakers work by using a large driver and a sturdy enclosure to produce powerful sound waves. Subwoofers can be passive, requiring an external amplifier, or active, which have a built-in amplifier. They are often paired with other speakers, such as satellite speakers, to create a full-range audio experience.
