Now we come to the classification of speakers we love best: subwoofers. If you've ever been to a nightclub and felt the music pounding in your ears -- or if you happen to have noisy neighbors who party way too loud -- you know all about the power of bass. Subwoofers are responsible for reproducing the lowest, deepest sound ranges that add body to any audio mix. Music just isn't the same without a good subwoofer.
We learned on the last page that component speaker systems consist of individual sound units connected together to accurately reproduce the sound from a CD, MP3 player or radio broadcast. Component subwoofers tie into the audio package, enriching the low frequency sound with powerful bass. As with coaxial and component speakers, you can spend hundreds of dollars on high-end component subwoofers. Two other necessary pieces of equipment will add to the expense: To install and run a subwoofer, you'll need a subwoofer enclosure and an amp (which we'll discuss later) for your system. The enclosure will ensure maximum performance from your subwoofer, while the amp will give it the power needed to deliver that deep bass [source: Sonic Electronix].
One word of warning about subwoofers: There is such a thing as too much bass. Crank it up too high, and you'll hear (and feel) powerful vibrations that distort the sound of your music. Find a happy medium that enriches your music with bass but doesn't rattle your windows with overpowering low frequency sound.
