http://www.bcae1.com will have a much more thorough explanation, but in a nutshell...

Crossovers direct what speakers play what frequencies. If you didn't have them, all your speakers would try to play every frequency in the material...you'd be hearing voices coming out of your subwoofers and burning up tweets with subbass. It's the crossover's job to filter out the appropriate frequencies for each driver, using a series of capacitors and inductors in various combos.

For example, a 60Hz low pass filter means that frequencies above 60Hz are attenuated, and frequencies below that point are allowed to play. Crossovers aren't brick walls, they gradually increase their attenuation - this is called the "slope". A 12dB/octave slope implies that the output will be 12 decibels down an octave above the crossover point - in this case, 120Hz.

It gets a lot more complicated than that, but those are the basics...pictures help you understand it a ton //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

Now we know why DBfan has what he has in his user title (even though he's a mod //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif)

The link Jim provided you with (www.bcae1.com) is a time-consuming read, to be sure, but for the novice-level enthusiast it is chock full of unendingly handy and worthwhile information.

Get comfortable, click the link, and have a read.
