When putting together a great home theater system, a subwoofer is a necessary purchase. The subwoofer is a specialized speaker designed to reproduce extremely low frequencies.
Difference Between Passive and Active Subwoofer Which is Better
For music that means acoustic or electric bass guitars, and for movies it means the rumble of a train moving down the track, cannon fire and explosions, and the big test: the deep rumble of an earthquake.
Before you can enjoy this, however, you need to integrate the subwoofer with the rest of your system. How you connect a subwoofer to the rest of your home theater setup depends on whether it is Powered or Passive.
Passive subwoofers are called 'passive' because, like traditional speakers, they must be driven by an external amplifier.
