What is a subwoofer and how does it work?
A subwoofer is a specialized loudspeaker designed to reproduce low-frequency sounds, typically below 200 Hz. It works by converting electrical signals into sound waves through a diaphragm that moves in and out. The larger the diaphragm and enclosure, the better the subwoofer can handle bass frequencies, resulting in deeper and more powerful sounds that enhance the overall audio experience.
Subwoofers can be active (with built-in amplifiers) or passive (requiring an external amplifier). They are commonly used in home theater systems, car audio systems, and professional audio setups to produce the deep rumble of bass in music and movie soundtracks. Their ability to handle these low frequencies makes them essential for achieving a full-range audio experience.
What factors affect the bass performance of a subwoofer?
Several factors contribute to a subwoofer’s bass performance, including its size, power handling, and enclosure design.
