The signal is AC (alternating current) which means exactly what it sounds like, The current will rotate directions. When the current is going one way the sub will be attracted to the magnet. When the current is going the other way it will be pushed away from the magnet. The rate that the sub moves back and forth produces the frequency the sub plays.

Subwoofers consist of two types; a powered subwoofer which is self contained and then you get a passive subwoofer which needs a external receiver/amplifier for it to function to the fullest. There is one problem with the passive subwoofer, the amplifier or receiver cannot deliver enough power to the subwoofer for it to produce the lowest frequencies.
