How many channels do you need for your home stereo system?
Almost all music is recorded in stereo (recorded to playback in more than one speaker channel).
When listening to music, you won’t ever need to use some speakers and not others.
Two speakers in the back distribute directional sound a lot better than a single center speaker.
When it comes to surround sound, how many channels your speaker setup has is only one factor.
Whatever you’re watching or playing will have to support the surround sound system you have set up.
