What’s your favourite kind of bar? Icecream, Chocolate, or maybe singles?

Well, if you are suffering from unsatisfied audio from your expensive new Television set, a SOUNDBAR can be your television’s new best friend. Soundbars have become quite popular in the last few years. The main reason behind it is that as the technology evolved, television manufacturers sacrificed volume for bigger screens.

The volume we hear on our inches long screen has become just as flat as the screen itself. Back then, when we were using large CRTs (Cathode-ray tubes), manufacturers were able to build powerful speakers because of the additional space inside the chassis. Richer sounds need big space and large drivers to be reproduced correctly.

Soundbars have become famous because unlike the other speakers; they do not require several messy wires to be attached and hence, do not take a lot of space. The growing market has led to lots of new innovations and discoveries in this area.

Nowadays, many soundbars come with an extensive list of features such as built-in subwoofers, additional drivers to enable central channel, and even multiple drivers to enable virtual surround sound.

A2.1 Soundbars

How Are a2.1 and 3.1 Sound Bars Different?

A2.1 Soundbars

The number 2 in A2.1 soundbar means that this soundbar comes with two channels; a left and a right channel. This soundbar comes with one external subwoofer. Subwoofers are specifically designed to produce low-frequency sounds that soundbars cannot make. An A2.1 soundbar can have several numbers of speakers on the left and right side, but they are paired up, all playing the exact same sounds.

If you are looking for a highly dynamic surround sound experience, an A2.1 soundbar is not capable of providing that. It does not offer a central speaker, which means that the dialogues get mixed with the sound and music. However, if you do not want to spend much on a sound system but want to get more than your regular television speakers provide, an A2.1 soundbar is a good choice.

A3.1 Soundbars

Unlike the A2.1 soundbar, an A3.1 soundbar comes with three channels, a left, a right, and a centre channel. The centre channel mainly provides dialogues and helps people hear more clearly. This makes a tremendous difference when you are watching movies or tv series. The central speaker makes people notice a considerable difference between the sound effects of a TV and a soundbar.

It also comes with an external subwoofer. An A3.1 soundbar does not provide rear speakers as A5.1, but the sound quality is much better than what A2.1 offers. The extra central channel prevents the dialogues from getting mixed with the music and sounds.

According to most experts, if you want good sound quality, do not invest in anything lower than an A3.1 soundbar.

The new and sleeker TV sets coming in the market typically have two speakers with around 20 Watts of total power. This might be okay for people who use their TV to listen to the news or as a background sound while working, but it is not ideal for people who want to watch movies or enjoy music on their television sets.

If you prefer high-quality sound, you will definitely appreciate having a soundbar. Apart from being an audiophile, listed below are some reasons you should get a soundbar for your living room immediately!

Simple to Use

If you have a soundbar, you do not have to worry about hundreds of messy cables lying around on the floor of your room or the living room. The soundbar is a neat and compact audio solution. You just have to place the bar beneath your television, and you’re good to go. You can also attach the soundbar with the wall if you do not have a table for it. They are also very easy to set up and install. So, even if you are not a tech-savvy person, you got it!


The Bluetooth feature of soundbars allows users to use in several different ways. Unlike most speakers, you don’t have to plug in the wires if you want to connect your mobile or tablet to listen to music or a podcast.

With soundbars, you can simply connect your phone, tablet, and even laptop with the soundbars and enjoy an incredibly immersive experience.

Modern Designs

Soundbars placed beneath the TVs give a very modern and aesthetic look. They come in a slim bar shape. The size and colour of the soundbar depend upon the model you are buying. Most people prefer getting soundbars in black colour as it amazingly compliments the other colours.

You can use a soundbar in your bedroom or a living room.


Unlike other speakers and home theatre systems, soundbars offer great sound quality on a budget. Soundbars come in all shapes and sizes, so you can get one according to your budget. If you are not sure which soundbar to get, you can start with a 2.1 or 3.1 and then add components later if you require.


If you are looking to invest in a soundbar because you cannot stand the poor quality sound your TV provides, we suggest that you invest in a reliable system. It is important to know what you are really looking for and then invest in a product because otherwise, your poor choices will cost you a lot of money.

If you want to get an average sound system that is not heavy on your wallet at all, you should go with the A2.1 soundbar. On the contrary, if you want a good quality sound system to enjoy movies and your favourite shows, you can go for the A3.1 soundbar.
