2 Channel System

A "typical" speaker for a two channel system (you need 2, one for each channel) has either a tweeter and a woofer or a tweeter and a midrange and a woofer. Some folks add a subwoofer, some do not. Some also prefer a single "full range" driver for each channel, that does not have a separate woofer and tweeter.

And some use 3-way and 4-way speaker systems for stereo. The number of speakers has little to do with the frequency range.

I think you will find that most decent home 2 channel systems will outperform any car stereo in terms of overall quality. Many of the seperate drivers developed for car stereo applications have come about as a result of trying to overcome the many shortcomings of the auto listening environment, most of which are aimed at increasing the HF response. It has most always been rather simple to get mid and LF response in a car. I won't even mention the total lack of imaging in car audio. This is not meant as a slam, just an observation of two completely different applications.
