A powered subwoofer is a type of speaker designed to produce low-frequency sounds, known as bass. Unlike regular subwoofers, powered subwoofers have a built-in amplifier, which means they can produce deep, rich sounds without needing an external power source. This makes them easy to set up and use in home theater systems or music setups. These subwoofers enhance the audio experience by adding depth to music and movie soundtracks. They are often used alongside other speakers, like satellite speakers or floor-standing speakers, to create a full-range sound. With a powered subwoofer, you can enjoy a more immersive listening experience.
