2.0 speakers vs. 2.1 speakers
Sure, a 5.1 (five speakers, one subwoofer) multichannel speaker system sounds pretty sexy. But even if you were to unearth one for $50 or $60, the quality would almost certainly be just as cheap. That money can buy a much better quality two-speaker system. These basic 2.0 stereo setups, which are comprised of just a left and right speaker with a single driver (the actual loudspeaker) in each, abound in this price range. Occasionally you can also find a decent 2.1 system—a pair of speakers to handle the higher frequencies and separate subwoofer for the bass. These take up more space but often produce more balanced sound. More on that next.
