Crossover

What exactly does a cross over, x-over do? Im stereo retarded sorry.

A cross-over splits the signal into blocks. It sends the higher frequencies to tweeters and the mid\lower frequencies to the mid. They can also be used to send only a certain range of lower frequencies to a sub.

Cross-overs that come with component speakers are matched to the frequency response of the speakers. The built-in ones that you'll find on amps are often adjustable for low-pass or high-pass operation.
