What is a Subwoofer?

Monday, 29 Nov 2010 04:13 PM

Subwoofers are generally bigger than their counterpart speakers, and also require more power to function, compared to the speakers. Subwoofers are now a part of any decent and “good” rated speakers, not to mention movie theatres, night clubs, and music theatres. And many different designs of subwoofers are available, such as bass reflex, infinite baffle, horn-loaded, and bandpass designs to meet different requirements. They generally appear in enclosures that allow space for them to make sound and boom away. Subwoofers can be made out of various different materials such as polypropylene, reinforced paper, Kevlar, aluminum, or carbon. Each material gives a subwoofer a different sound.
Car subwoofers are the best example of how advanced subwoofers have become in general. Unlike enclosed subwoofers, car subwoofers don’t enjoy the space liberty. Generally, car subwoofers are installed in the trunk or backseat space and are therefore mostly hidden. Around the year 2000, multiple car subwoofer manufacturers came out with non-circular shaped car subwoofers. These car subwoofers are said to contain some sort of distortion penalties. What this means is: in situations of limited space and mounting, these car subwoofers provide larger cone area and therefore larger output.
Home subwoofers, however, have a lot of space available to them. The functionality of home subwoofers is found applicable in movies and music alike, which have a lot of low-frequency sound content. Some home subwoofer manufacturers like Bose and Polk have made noticeable innovations. Recently, “Home theatre in a box” home subwoofer systems have become popular as low-cost subwoofer solutions.
For maximum efficiency, subwoofer placement should be such that the subwoofers are located in the corners of a room, closer to listeners and far away from large room openings and gaps. Moreover, it is advisable to avoid subwoofer placement close to satellite speakers. In the case of some music systems, the subwoofer placement is such that they are placed on the floor separately from the normal speakers; the latter may be arranged in a stack.
MTX Jackhammer subwoofers are the most recent and raved about marvels among all subwoofer species. Jackhammer subwoofers are the largest and loudest subwoofers that are meant for use in automobiles. The diameter of a jackhammer subwoofer measures about 22 inches, and the subwoofer can handle a total of 6000 watts within a 26-Kg strontium ferrite magnet. The jackhammer subwoofer also has an aluminum heat sink and has been used in popular shows like MTV’s Pimp My Ride.
Perhaps, the most advanced of subwoofers are the Kicker subwoofers, available in different models and sizes. Kicker subwoofers are certainly not for the weak hearted, as these output up to 10,000 watts of power. The Kicker designs are also groundbreaking, and they promote a woofer technology called the “square woofer technology.” Yamaha subwoofers have also brought about quite a revolution in the world of subwoofers. They are indeed world-class and one of the dream things to possess for every audioholic.
