Cheap Speakers : Subwoofer
Subwoofers are where the power comes from; that spine-tingling, window-rattling bass that makes the neighbors call you up and say, “WTF?” Ahh yes… a sound system just isn’t a sound system without subwoofers.
Ranging anywhere from 8″ to 21″ in diameter, a subwoofer is a complete speaker in itself which is specifically made for those low frequency sounds to back up the main speaker. They range is usually about 20-200 Hz. Most all standard sound systems include subwoofers, which are cased invariably inside braced plastic or wooden boxes, which vary in shape according to speaker placement.
There are many different things to consider when thinking about subwoofers: equalization, phase control, amplification, servos, etc. It’s all very confusing for the layman or laywoman. Basically all you need to know is that these things are responsible for that pounding, vibratory beat that allows you to feel the music. They are found in most car stereo systems, home theater systems, and stadiums.
Prices vary, just like everything else. You could spend anywhere from 50 dollars to 500 dollars depending on which particular brand or model you purchase.
There is much ado about where to put a subwoofer in order to gain maximum benefit, especially in the home environment. While it is often said that a subwoofer’s place is in the corner of the room, which indeed is often good placement, it may not always be the best option. It’s probably best, if possible, to have an expert come to your home and examine the situation firsthand, as every room’s acoustics varies, so it may be best to leave the position of your subwoofer to an expert.
It should also be noted that no one should use a subwoofer as their sole or main speaker, because subwoofers are specifically designed to enhance the lower frequency sounds, or bass, and not the lighter frequencies or treble.
