What do soundbar channel numbers mean?

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

Three types of speakers are placed on pedastals near each other: a main soundbar unit, a subwoofer, and two rear speakers. There are three numbers on top: 11, 1, and 4, labelled front and surround channels, subwoofer channels, and up-firing channels, respectively.

If you're thinking of adding a soundbar to your setup, a good place to start is understanding soundbar channel numbers. They tell you the number of channels the soundbar has. The number can make a big difference for audio quality and surround sound immersion.

11.1.4ch - The latest innovation in soundbars

Introducing the latest innovation in the soundbar market: the 11.1.4ch configuration. Let's use this as an example to understand the meaning behind each channel number. The first number indicates the number of forward-projecting horizontal channels. The second number is for the subwoofer, while the third signifies up-firing channels. In the case of an 11.1.4ch soundbar setup, it breaks down like this: 11 primary standard audio channels, 1 subwoofer for enhanced bass, and 4 up-firing channels for overhead effects.

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.

The second number represents deep bass frequencies

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 frequencies that add real depth to your audio. Subwoofer installation is also relatively straightforward.

What does the third number stand for?

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.

Model recommendations by soundbar channels

The greater the number of channels in your soundbar, the more realistic and immersive your audio becomes. To recreate a cinematic atmosphere at home, consider starting with a 5.1ch soundbar as your foundation. If you’re already thinking about Dolby Atmos and DTS:X content, it’s crucial to purchase a soundbar equipped with upward-firing channels to truly bring the audio to life.
