In case you do not know already, even the best and highly efficient television sets that you buy from the market can have a very poor sound which although is surprising but is quite true.

When you look into soundbars, you will come across 2 different types- 2.1 channel soundbars and 3.1 channel soundbars. It is important to know the differences between the two so you buy the one that best serves your particular requirements.

So what is the key thing that sets these two types of soundbars apart? A 2.1 soundbar model features a right and left channel, along with a subwoofer. On the other hand, a 3.1 soundbar features 3 channels instead of 2: center, right, and left and a subwoofer as well. The key difference 2.1 and 3.1 soundbar is that a 3.1 channel soundbar provides crisper and clearer dialogue. That is owing to the fact the center channel chiefly focuses on the audio of dialogue.
Now let us dive into detail regarding how the 2.1 and 3.1 channel soundbars stack up against one another.

2.1 vs 3.1

You have to take these important considerations in mind when it comes to the 2.1 channel vs 3.1 channel.

2.1 Soundbar Setup vs 3.1 Soundbar Setup

When you talk about the setup of soundbars, you should know that a 2.1 channel soundbar setup is very basic. You have a right and a left channel that the manufacturer has incorporated in the soundbar, in addition to an extra external subwoofer. There is no denying that soundbars having a 2.1 setup will surely be a significant upgrade from the built-in audio of your television. You will have a strong and clear right and left speaker sound, though the soundbar will not offer a truly immersive surround sound that you can expect from an advanced and contemporary setup. If you are in the market looking for an upgrade to the built-in speakers of your television and do not wish to pay a hefty sum for it, then a 2.1 channel soundbar is an ideal choice for you.

On the other hand, a 3.1 channel soundbar tends to sound slightly different from its 2.1 counterparts. Furthermore, the former is a tad more costly than a 2.1 soundbar. As you are incorporating the middle channel speaker within the device (this is the main difference between a 2.1 and 3.1 soundbar), what it does is contribute towards a more dynamic and immersive sound. Although you will not be including any rear speakers to obtain genuine surround sound but are adding greater dimension and sound (room-filling) with the additional channel. According to several soundbar experts, this gets you quite close to a true surround sound experience.

Compared to a 2.1 channel soundbar, a 3.1 setup will most likely provide you with superior clarity of sound along with dialogue, as dialogue chiefly originates from the middle channel speaker of the device. The dialogue that comes out from a 2.1 channel soundbar device will be mixed with music and sound effects. As a result, the dialogue might sound a trifle less clear and crisp than what you can expect from a 3.1 channel soundbar system.


It is true that both of the 2.1 and 3.1 channel soundbar devices include right and left channels. That said, the addition of dialogue boosting center speakers present in 3.1 soundbars jack up its price tag. Therefore, you can expect to fork out around 1-1.5 times more for a 3.1 device in contrast to a 2.1 one.

Extra capabilities like audio technology, voice control, and sound modes may also contribute to the difference in price between these two types of soundbars.


Soundbar devices happen to be quite compact and compressed speaker systems that include a lot of incredible features into a subtle and slim body. It is likely that this might not leave adequate room for a subwoofer to do justice to deep bass notes. This is precisely why 3.1 and 2.1 soundbars come with a bigger-sized external subwoofer.

Owing to the extra center channel present in the 3.1 channel soundbars, these models are usually larger than the 2.1 soundbar devices. Not every person has the room in their house to easily accommodate a bigger soundbar. Therefore, if you have a small space in your entertainment room, a 2.1 channel soundbar might be sufficient to reach the high standards of a 3.1 model.

However, all soundbar devices conform to a slim standard design and can be easily mounted on your wall or placed on a flat surface. Hence, both the 3.1 and 2.1 channel soundbars offer a considerable amount of freedom in placement.


A common denominator between both 3.1 and 2.1 soundbar devices is that they come with built-in Bluetooth. Wi-Fi happens to another wireless connection that you can find in both of these soundbar types, though only the more expensive ones.

Bluetooth technology enables users to easily stream any kind of content (movies, songs, etc) from their smart phones or tablets to the soundbar to completely decode audio formats. There is no doubt that when you get a Bluetooth supported soundbar device, it can do truly wonders in cleaning up any cable mess which is unsightly to look at!

In addition, External subwoofers that you get with 3.1 and 2.1 soundbars can work seamlessly on Bluetooth technology as well.
