Is 5.1 better than 2.1?
Again, if you are a cinema fan, there’s no discussion here – a 5.1 system is a better option. Compared to a 2.1 system, 5.1 system has a dedicated center channel and two surround speakers. The center channel is responsible for most of the dialogs in movies, which means that you get better dialog clarity with a 5.1 system. Two surround channels will expand the soundstage and add another dimension to the sound making the movie-watching experience more immersive, more life-like.
