What is the difference between a 2.1 and a 5.1 soundbar?

There are different soundbars out there to choose from, and they all have different compatibilities and specifications which set them apart. One of the most common things you’ll see is a 2.1 soundbar, or a 5.1 soundbar.

But what is the difference between 2.1 and 5.1, and which one is going to be most suitable for you? Well, let’s take a quick look at firstly how they’re different, and then which one you should go for.

What is the difference between a 2.1 and a 5.1 soundbar?

The difference between a 2.1 soundbar and a 5.1 soundbar is the setup that they’re used in, and the amount of speakers they have. A 2.1 soundbar has a left and right speaker (2) and is intended to be used with a subwoofer (2.1). A 5.1 soundbar has a left, right and a center speaker in it (3), and is intended to be used with 2 additional surround sound speakers (+2), and a subwoofer (5.1).

This is the easiest way to understand the difference between 2.1 and 5.1 soundbars. But, this isn’t exactly what 2.1 and 5.1 means, as soundbars aren’t traditionally part of this sort of speaker setup.

What is a traditional soundbar setup?

Actually in a traditional setup, a 2.1 sound system consists of one subwoofer, and two speakers which are placed either side of the sub, which is in the center.

And a 5.1 system consists of one subwoofer and five speakers spaced out around the room, which is better for generating a full surround sound system.

So what’s a 2.1 and 5.1 soundbar, then?

Generally, soundbars have been used as an all-in-one device, which was always intended to be used alone with a television. So, there would be no additional speakers and not even a subwoofer.

However, nowadays a soundbar can just make up part of a full sound system, and it’s been integrated into a 2.1 and a 5.1 design.

Because a typical soundbar has two speakers in one, then this type of soundbar is considered to be a 2.1, and can be used in the same 2.1 system. So, the left and right speaker are replaced by the two speakers in the soundbar, and you just use an additional subwoofer with the soundbar.

2.1-soundbar
A 2.1 soundbar relies on just itself and it’s two speakers, in addition to a subwoofer.

But, a 5.1 soundbar is designed to offer more than this. It actually has three speakers within the soundbar itself, with an additional speaker in the center of the device. Then, all you need is two additional speakers to create a full surround sound experience, with an extra subwoofer.

5.1-soundbar
A 5.1 soundbar has three speakers, and is made to be used with an additional two surround speakers and a subwoofer.

What other variations of 5.1 soundbar are there?

Even though these are the most traditional setups of soundbar, they aren’t the only options out there. You can also find different variations of soundbar which may suit your circumstance better.

If you’re looking to use a soundbar alone with no additional speakers, then you could opt for a soundbar with an integrated subwoofer. This replaces the center speaker with a sub, and still has a left and right speaker inside the soundbar. It’s a good choice for those looking for more bass within one speaker.

You can also look at soundbars which have integrated surround sound speakers in them. So, they’ll have one centre speaker, with a left and right either side of this speaker, and then two additional speakers at the edges of the soundbar responsible for creating surround sound. They can be a good option if you don’t want any additional surround sound speakers.

What is a 7.1 system?

A 7.1 system is another form of setup which uses even more speakers. It’s essentially the same as a 5.1 system, but it just uses an additional left and right surrounded sound speaker. Strategically placing these speakers around your cinema room can ensure that you get an improved watching experience.

Most people will find that a 7.1 system might be a little too much, in terms of both cost and the amount of space it takes up. However for those looking for the very best, this could be a wise choice.

Conclusion

Overall, if you’re looking for a full audio experience with your soundbar, then a 5.1 is going to be the better choice. You’ll get a better audio quality from the soundbar itself, and it will be better for those trying to create their own home cinema. But if you’re just looking for a standard soundbar for watching the TV, then a 2.1 sound will do the job just fine.
