We want you to be a fully armed and dangerous audio consumer. To attain this exalted condition, you will need to know the terms, the technology, the schemes and tricks of the trade. In this section, you will find more than you ever wanted to know about audio equipment and systems but were afraid to ask. If you take a look at the navigation bar on the right, you will see that you can move around in this subsection quickly to find out what you need to know about speakers, amplifiers, speaker boxes & enclosures, and just about anything else. And don't worry if you get to feeling lost sometimes; using the main navigation bar on the left and the section navigation bar on the right, you can quickly jump to any location on the site. To help get you started, here's a little preview of exactly what you will find here.

GLOSSARY (Understanding Audio Terminology)
Ever wonder exactly what "MAX Power" means as opposed to "RMS?" Or what about "VAS," "dB," "THD," and all those other terms audiophiles tend to throw around? You will find all these answers and many many more in our Glossary. The Glossary is basically a dictionary of audio terms, with easy-to-understand explanations of what they mean.

Whether you are buying or building a speaker box for your car or an enclosure for your home, you will find everything you need to know in this section.

AMPLIFIERS
Finally, we give a comprehensive explanation of amplifiers--what they do, how they do it, and which one would be just right for your needs. For the confusing matter of power, we have a page on, What's a Watt? We also provide plenty of information on general installation issues with tips on wire gauges, dealing with noise, and impedance matching.
