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 operates by converting electrical signals into sound waves, focusing on the bass frequencies that regular speakers may struggle to produce accurately. This is achieved through a larger driver size and a robust enclosure, which helps the subwoofer create deep, resonant low tones that enhance overall audio quality.
The working principle of a subwoofer involves moving a diaphragm back and forth to create sound waves. As the amplifier sends an electrical signal to the subwoofer, the diaphragm vibrates, generating low-frequency sounds. Most subwoofers also incorporate a crossover network, which filters out higher frequencies, ensuring that only bass sounds reach the subwoofer, thereby optimizing its performance in delivering powerful, clear bass.
