The main difference between active and passive subwoofer is an in-built amplifier. Active models have it, while passive not. Nevertheless, the second can produce better quality, which makes it important to get the best passive subwoofer.

The passive subwoofer is a classic because the original form was already built in this way. The subwoofer itself has only one membrane and does not generate any power. This power comes from the power amplifier. Therefore, the power amplifier needs both power and the input signal from speakers.
