What is a powered subwoofer and how does it work?
A powered subwoofer is a type of loudspeaker designed to reproduce low-frequency sounds, typically below 100 Hz. Unlike passive subwoofers, powered subwoofers have an integrated amplifier, which allows them to be directly connected to a sound source, such as an AV receiver or preamp. This integrated amplifier is specifically tuned to optimize the low frequencies, delivering powerful bass that enhances the overall sound experience.
The design of powered subwoofers also often includes a frequency crossover, which separates the low frequencies from the rest of the audio spectrum. This ensures that the subwoofer only receives the sounds it is designed to play, allowing other speakers to focus on mid and high frequencies. Together, these components work to create deep, resonant bass that adds depth and dimension to music, movies, and gaming.
