A subwoofer is a woofer, or a complete loudspeaker dedicated to the reproduction of bass audio frequencies, from perhaps 150 Hz down as far as 20 Hz, or in rare cases lower. Also known as "subs", these are used to augment the low frequency performance of main loudspeakers. Subwoofers are constructed by mounting one or more woofers typically between 8" and 21" in diameter in a well-braced wood or plastic enclosure. Subwoofers have been designed using a number of speaker enclosure designs, including bass reflex (with a port or tube in the enclosure), infinite baffle, horn-loaded, and bandpass designs, each of which has advantages and disadvantages in efficiency, size, distortion, cost, and power handling. Passive subwoofers have a subwoofer driver and enclosure and they are powered by an external amplifier. Active subwoofers include a built-in amplifier.
