Best Passive Subwoofer For Home Theater

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.

Advantages of passive home subwoofers

Unlike an active subwoofer, a passive subwoofer works more like a conventional loudspeaker. A crossover defines the frequencies that it outputs. The passive subwoofer has the advantage that the power amplifier works independently of the actual subwoofer, and the device is, therefore, less prone to interference.

  • With a passive subwoofer, the bass is relieved of the other speakers;
  • It has more power and plays a stronger bass;
  • No hum or clicking side sounds and noises;
  • Mainly covers the low frequencies;
  • A passive subwoofer is compatible with a lot of different devices;
  • The power amplifier and unpowered subwoofer can be exchanged and individually adjusted at any time.
