From the Wikipedia overlords:
A subwoofer is a loudspeaker which reproduces bass frequencies from about 20 Hz to about 200 Hz. Frequencies 16 Hz or lower are more felt than heard. Subwoofers reproduce frequencies from about 35 Hz to about 200 Hz. It is difficult for small loudspeakers to reproduce frequencies below 40 Hz, especially above 100 dB, and so it is often advantageous to use a loudspeaker dedicated to this task.
Ok, so I have a 10 inch bazooka tube in the back of my car, but this? This is an example of a pure and utter asshat. The kind of person that has this running in his truck can be heard for several city blocks.
