What is a Subwoofer?
A subwoofer is a specialized speaker responsible for the most difficult duty in home theater. It produces the very deep, room shaking notes that add a magical effect and balance the sound. This requires providing lots of power to fill a room with sound, and large mechanical motions of the subwoofer. When you hear about Dolby 5.1, the “.1” refers to the subwoofer’s special role in a surround sound system consisting of five speakers and (at least) one subwoofer.
Your current speaker system probably has a woofer, but not a subwoofer. This type of woofer will play some low frequencies but will not deliver the full-range, authority and high definition bass that todays exciting digital entertainment sources offer. Only a quality subwoofer will bring these sounds to you with full impact and clarity. A well engineered subwoofer very precisely matches a bass speaker (subwoofer), an amplifier (power), cabinet and crossovers (frequency dividing networks) all in a single efficient package that recreates bass you not only hear, but feel. The deep bass that you feel is important because it invokes an emotional reaction to the event or show and fully involves the audience in the event.
A subwoofer is a speaker that is designed to reproduce very low bass frequencies (usually those between 20 Hz and 125 Hz). These speakers tend to be large in size (between 8″ (20.3cm) and 15″ (38.1cm) in diameter) and require more power to operate than their small speaker counterparts. A subwoofer is used in order to provide the powerful audio rumble or punch commonly used in movies and music. Common uses of subwoofers include installation in one’s car or, more commonly, in home theater use. In either application the subwoofer is not considered a stand alone device but helps to fortify the higher pitched sound produced from the speakers. While never entirely necessary to reproduce sound from a car or home audio system, subwoofers have reached great popularity due to their ability to pack a large, low frequency punch in a small space. The quality of a subwoofer depends mainly upon its construction and the components used in manufacturing it. Subwoofers can be made out of many different

Unquestionably, every music and home theater system needs a subwoofer.
