Subwoofers are a special type of speaker capable of reproducing the lowest audible frequencies. Subwoofers play an integral role in any two-channel or surround system, but deciding which one to buy is not as simple as picking the one with the largest woofer and lowest quoted frequency response. You need to make sure it’s right for your room and for your system. Setting aside for the moment your specific room size and tastes, or any unusual circumstances, let's discuss what makes a good subwoofer. A good subwoofer should have low distortion to create realism, good low frequency extension for authoritative bass you can feel, and ample output to ensure plenty of dynamic impact and excitement. The most elusive subwoofer quality is low distortion to achieve accurate bass tones. Unfortunately, most subwoofers have a distortion rate of 25% to 30% which translates into a severe lack of detail and clarity. These subwoofers sound muddy, booming and lack realism in home theater and accuracy in music systems. Choose a subwoofer low in distortion. Few subwoofer manufacturers illustrate distortion figures, so listening to a good music recording with deep bass content will be important. A subwoofer with low distortion will be able to unlock the important element of bass in today's entertainment.
The most common type of subwoofer is self-powered, which means it has a built-in amplifier. Powered subwoofers usually provide volume (gain) and other controls that can be adjusted separately from the home theater receiver. A powered subwoofer needs a connection to the Sub output from a receiver (you don't need an extra amp between the subwoofer and the receiver). This connection setup takes the audio power load away from the amp/receiver and allows the amp/receiver to power the midrange and tweeters.
An external amplifier powers a passive subwoofer in the same fashion as other speakers in your system. Low-frequency bass output needs more power to reproduce low-frequency sounds. Suppose you connect a passive subwoofer to the receiver's speaker terminals instead of putting a separate amplifier between the sub and receiver. In that case, the receiver must output enough power to sustain bass effects in the subwoofer without draining the amp. The amount of power depends on the passive subwoofer's requirements, the size of the room, and how much bass you desire.
The crossover is an electronic circuit that routes all frequencies below a specific decibel point to the subwoofer. All frequencies above that point are routed to the main, center, and surround speakers. Typically, a good subwoofer has a crossover frequency of about 100 Hz.
Wired or wireless?
A growing number of powered subwoofers offer wireless connectivity. The wireless capability eliminates the need for a long connection cable between the subwoofer and the receiver. A wireless-enabled subwoofer usually comes with a transmitter kit that can be plugged into the subwoofer outputs of any home theater receiver. The transmitter connected to the home theater receiver transmits low-frequency audio signals to the wireless subwoofer. In turn, the wireless receiver built into the subwoofer allows the built-in amplifier to power the speaker driver, producing the needed low-frequency sound.
