What Do Channels Mean On A Soundbar?

Installing a new soundbar begins with knowing the best and worst places to put it, as you want to ensure the best sound possible. It's also good to understand the channels, as they describe how your soundbar is designed to reproduce audio. For example, in the 5.1.2 soundbar designation, each number represents a different type of audio channel.

The first number represents the primary audio channels. These channels are responsible for dialogue, music, and sound effects. The second number is for the subwoofer channels that the soundbar uses for bass. If there is a third number, it represents height channels, or audio that creates the effect of sound coming from above the device. This is reserved for overhead effects like Dolby Atmos. A 5.1.2 soundbar includes five main channels, one subwoofer channel, and two height channels. In contrast, 11.1.4 designs are considered among the best soundbars for audiophiles, as they add more channels for a wider and richer sound overall.

The reason some soundbars have more primary channels than others is due to the device's setup. These channels can include dedicated audio for the left, right, and center speakers. But they can also have additional surround sound channels that help create a wider listening space. The number of height channels can vary because different soundbar designs can include more or fewer of these upward-firing channels.

A soundbar's number of channels can help influence your decision on which model to buy, but there's actually more to consider than that. That's because while more channels can add more speakers and audio separation, that configuration may not be the best choice for a smaller room. A basic 2.1-channel soundbar could be enough if you just want to improve your TV's audio, while a larger system with additional speakers, subwoofers, and rear channels is ideal for creating a surround-sound experience.

One important feature you may need is the center channel, which isn't included on every soundbar but can make voices easier to hear. The center channel can improve dialogue clarity in movies and TV shows because it is a dedicated channel designed primarily for that purpose. If you're looking for deeper bass, you may find it with some of the best soundbar and subwoofer combos.

But beyond channels, the physical size of the soundbar and the space where it will be used are also important factors to consider when buying. This means choosing a model that fits your setup, including the available space and whether you're using an entertainment stand or placing it under a wall-mounted TV. The soundbar should match both your room and your TV to help ensure it delivers the right balance of performance and usefulness.
