What is the Difference Between a 2.1 and 5.1 Soundbar?

After getting your dream TV now, you will want to have a great sound system that will also match your TV. Sometimes higher-end TVs also come with speakers that do not sound great. Installing a sound system is a common and easiest way to upgrade your entertainment system. But questions can come to your mind that, what kind of speaker will be best for you, or what’s the difference between a 2.1 and 5.1 soundbar system?

So let’s see what the difference between a 2.1 and 5.1 soundbar is? A 5.1 system has 6 speakers including the left and right in front and a center speaker. It also includes rear left and right speakers plus a subwoofer for the surround sound experience. A 2.1 system only has 3 speakers, two in front for the left and right channels, plus 1 speaker in the back to provide a high-quality sound experience.

In a 5.1 soundbar system, all the front channels are generally built-in to the soundbar, and the surround speakers come separated. But one thing you should remember is that adding more speakers doesn’t just add more volume; they also help the system improve the surround sound quality. It also helps you give you a unique entertainment environment.

Unfortunately, A sound system that is 5.1 is not for everyone. If you are going to buy a system, make sure to think about the factors so you can choose the perfect one for your needs.

2.1 Channel Soundbar

A 2.1 Channel Soundbar is formed on the Left and Right Channels in the Soundbar and a Separate Subwoofer.

A 2.1 channel soundbar usually comes with at least two speakers (sometimes more). They are separated into two channels, left and right. It also comes with a separated subwoofer. The extra speaker is not only for increasing the volume. More speakers help you to enjoy a more authentic surround sound experience.

With a 2.1 soundbar, you will be able to enjoy the clear sound from the left and right channels of audio. This sound system is pretty standard, but it will not improve your listening experience in a significant way.

With a 2.1 soundbar, you will get a left and a right channel only. These soundbars come with both “stereo” and “surround sound” settings, but unfortunately, in the 2.1 soundbar system, both settings will sound almost the same.

5.1 Channel Soundbar

A 5.1 soundbar system usually comes with three extra speakers or channels than a 2.1 soundbar system. So obviously, it will make a much richer sound and enhance your listening experience. It comes with a front left, front right, front center, surround right, surround left, and a separate subwoofer included.

The front speakers are usually built into the soundbar itself, where the surround speakers and the subwoofer is separated. But sometimes, all five sound speakers or channels are built into the soundbar. After being located into the soundbar itself, the additional two speakers still work as surround speakers.

5.1 Channel Soundbar with Separate Surround Speakers

So you can say that the traditional 5.1 surround system has three channels in the front, two surround channels, and a subwoofer.

The separated surround speakers can be placed anywhere to the back left and back right of the room. With a 5.1 soundbar system, you will be able to enjoy a ripe sense of left and right sound with additional depth.

That depth increases the entertainment experience. It can give you the experience that just can’t be matched with a few front speakers. It will make the sound more realistic. You will feel like the explosion in that action movie is happening right behind you. Even you will be able to locate from where the enemies’ footsteps are coming from in the video game.

5.1 Channel Soundbar with Integrated Surround Speakers

We have talked earlier that some soundbars come with the two surround channels built-in the soundbar itself. But the surround speaker comes angled so that they can output soundwaves in a very particular way.

The integrated surround speakers output the sound so that the soundwaves reflect from the back of your room, and they sound like the speakers are actually situated behind you. When in reality, the surround speakers are actually in front of you.

But it would be best if you remembered that this thing doesn’t work with all room sizes and shapes. It works great in a more boxed or closed-off room. But if the room is very open, the soundwaves will not bounce perfectly, and the speakers will not work great.  

But after all, the 5.1 soundbars with integrated “surround” speakers still sound really amazing!

What if There’s a 3rd Number?

Some of the 5.1 surround soundbars come with a third number, such as 5.1.4. It means that the soundbar directs some of its sounds upward. So that the sound can bounce in the ceiling and you can enjoy a new dimension of the surround sound.

A famous sound speaker, The Nakamichi Shockwave Pro 7.1.4 (on Amazon), also comes with this technology. This soundbar uses its satellite speakers, and it really sounds extremely well.

Conclusion Between 2.1 and 5.1 Soundbars

Adding more speakers does not ensure you give you better sound. 2.1 soundbars also come with high-quality speakers, and they also can please anyone. These high-quality speakers can also be found in 5.1 surround soundbars, but you can also find 5.1 systems with sub-par speakers. It really enhances the quality of the speaker drivers and soundbar enclosure.

Before you buy anything, you have to make sure that what sound aspects are important for you and which one will be best for your budget. Moreover, you should also think, is it really worth it to sacrifice a surround sound system for top-quality speakers or sacrifice top-quality speakers for a surround system? Would you like to enjoy a surround sound experience with a fair speaker quality?

Benefits of Soundbar Systems

Controlling Soundbars with Universal Remotes

You might ask that why you should buy a soundbar at all. For that, you should know that Soundbars are convenient and they can give you a great sound quality also. Just look at a 2.1 soundbar. It can give you a true quality sound with just a single soundbar and a subwoofer.

With a 5.1 soundbar, you can get a few more speakers, and it can enhance your audio experience even more. If you want to skip the hassle of wires, you can buy a Bluetooth surround speaker so that you can easily set it up.

To set up a traditional surround sound system, you have to give effort and connect all the speakers correctly via cables. But with a soundbar, you don’t have to take that much hassle. So you can say that it is the easiest way to elevate your listening experience.

Benefits of a Soundbar’s Easy-Setup Subwoofer

Subwoofers usually come with traditional surround sound setups. In 2.1 and 5.1, the 2 and 5 mean the number of sound channels it has, and the “.1” indicates the subwoofer. They are very important for sound quality. In a traditional surround sound setup, you have to connect the subwoofer via a cable.

But in almost all soundbar systems, you do not have to connect a subwoofer via cables. You will be able to connect them easily with the help of Radio Frequencies via Wi-Fi or Bluetooth.

When you use the built-in speaker of your TV, do you ever noticed that the audio is becoming distorted or fuzzy? It is because the built-in speakers are not so powerful. So they can’t handle the extreme pitches (from the high squeals to the super low rumbles).

A subwoofer is actually a dedicated bass speaker, so you can hear the bass more clearly and strongly while using a soundbar setup. Even the floor can rumble from the bass, but the subwoofer will not get damaged, and you will hear a clear sound.

Not Everyone Prefers 5.1 Soundbar Systems

If your priority is convenience, then you should go for a 2.1 soundbar instead of 5.1. Because setting up a 2.1 soundbar is much easier than setting up a 5.1 soundbar because there are fewer speakers.

Though a 2.1 soundbar comes with two speakers, these speakers are built into the soundbar.

There is a subwoofer also. So you just have to set up these two pieces. And enjoy a superb sound. You cannot find a better balance between convenience and quality than a decent 2.1 soundbar system offers easily.

Price Difference

5.1 and 7.1

After all, now you can ask, what’s all this going to cost you? More speakers will cost you more, and it is not surprising at all. But the 5.1surround soundbar might not be that much more costly than a 2.1 soundbar system.  

So if you are looking for soundbars, you may find a 5.1 soundbar for less than $200. If you do not have any issues with the budget, you can easily spend hundreds of dollars more on high-quality speakers with a wireless setup.

JBL is a famous speaker manufacturer. You can find their wireless 5.1 soundbars with detachable surround speakers on Amazon. You can also go for the bigger systems, such as the 7.1 soundbars if your budget allows you to do that.

Related Questions

Question

What does 3.1 mean on a soundbar?

The three means that the soundbar has three sound channels. Those are the left, right, and center channel. And the “.1” means the soundbar also comes with a single subwoofer.

Are standard TV speakers really that bad?

If you love high-quality audio, then the answer is YES. But Casual TV viewers may not mind some distorted voices or blown-out bass; usually, they’ll only notice it at high volume. But if you want a clear and strong sound at any volume, then you should install an extra sound system.

Are soundbar systems the only alternative to standard TV speakers?

No, there are some other alternatives also. It depends on anyone’s personal choice. Such as, Musicians may go for vintage analog speakers to match their vinyl collection, while Tech lovers may choose smart speakers so that the speaker can communicate with smart home systems and give you the output of superb audio quality with voice-activated software like Amazon’s Alexa or Google Home.

But after all, we just want to say that soundbars are a great choice for those who are looking for quality sound with a convenient, fairly affordable, and easy installation process.
