What is the difference between 2.1 channel and 5.1 channel?

The ".1" represents the subwoofer. In most package deals for 2.1 or 5.1 systems, this subwoofer will be passive, meaning it receives all power from the receiver. A 5.1 system is a bit more complex and will give you that true surround sound feeling. It will give you 4 bookshelf speakers and a center channel speaker.

What does sound bar 5.1 channel mean?

Much of surround-sound terminology boils down into numbers such as 2.0, 5.1, and 7.1. The first number represents the number of speakers or main audio channels involved, and the 1 or 0 after the decimal point indicates whether the system has a subwoofer or supports a low-frequency effects channel.
