We hear the world with two ears giving us the ability to locate sounds around us. When we listen to live music we hear it with two ears. This why music is recorded in two channels. Most television is recorded in two channels. Movies are the only format in which more than two audio channels are used. Two speakers are usually enough for ambient sound in any room. Audio however is not like lighting. In any space there will always be a listening position to take into consideration.
