The choice of the home theatre system will depend on the size of your room and other requirements; there are different types of home theatre units available. For small-sized bedrooms or if your main requirement is listening to music, you can opt for a 2.1 channel system that comes with a subwoofer and two satellite speakers. For larger-sized rooms, you can buy a 5.1 home theatre system for a mesmerizing surround sound experience that can take you right in the centre of the action.
