What do soundbar channel numbers mean?

Get to know the soundbar channel numbers before purchasing a soundbar – each one signifies a different audio function.

Let’s dive into the various channel numbers

In a basic 2.1ch system, you'll find left and right channels along with a subwoofer. Another frequently used configuration is the 5.1.2ch, which includes 5 horizontal channels (right, left, center, and two side channels) along with a subwoofer and 2 up-firing channels. Similarly, in a 9.1.4ch soundbar setup, you'll find 9 horizontal channels, one subwoofer, and 4 up-firing channels distributed across both the soundbar and
the rear speakers.

And there is one subwoofer next to a console with sound waves coming from the bottom.

What does the first number mean?

The first number of any soundbar configuration always indicates the number of forward-projecting horizontal speakers. For instance, 5.1.2 means that you have 5 horizontal channels delivering your primary listening experience.

There is a closeup of a subwoofer next to a TV console. There are sound waves coming from the bottom. Three numbers are on the bottom: 9, 1, and 4.

What does the second number mean?

When the second number is 0, that means there's no subwoofer channel in the soundbar. But it's best to opt for a soundbar with at least one subwoofer because they produce deep bass frequences that add real depth to your audio. Subwoofer installation is also relatively straightforward.

What does the third number mean?

Like the 11.1.4ch setup, many premium soundbars have a third number. These channels are used to create incredibly immersive audio experiences by adding height to the sound, and making it feel like sound is coming from above you. These effects are among the most impactful aspects of virtual surround sound.
