Why Have A Soundbar With A TV?

It is becoming common practice for people to add more power and volume to the entertainment they get from their TV systems.

Besides, with the increased access to live video streaming from smart TVs, you need the real theater experience while enjoying the movies from home.

Adding a soundbar to your TV, therefore, brings more depth, power, and volume to your entertainment. Although some of the built-in TV speakers may sound really good, the performance you get from soundbars is unmatched.

How Do I Know If A Soundbar Is Compatible With My TV?

Generally, the term compatibility is used concerning connectivity. This is to say that a soundbar is only compatible with the TV which can seamlessly connect and play sound.

Regardless of whether a soundbar matches your 55-inch TV or not, it is more important to consider the kind of connection you want between them. For modern systems, it is important to consider HDMI ARC and HDMI eARC that allow your TV to output audio to your new soundbar.

Modern soundbars however come with a wide variety of connectivity options such as optical ports, USB inputs, and wireless connectivity (Bluetooth and Wi-Fi) on top of the HDMI. We have discussed some of the additional factors to consider when buying a soundbar for enhanced compatibility below.

Point Of Placing

A soundbar can be either placed below or above the TV set. It is recommended that when placing your soundbar its grilles should face the room and not the wall.

Where you place your TV and the amount of space available around it will therefore define the type of soundbar that works best for you.

On the other hand, and aesthetically speaking, the soundbar should not be wider than the TV. When both of them are exactly the same width, your TV and soundbar get an even look that is perfect for your home interior too.

Number Of Channels Needed

When buying your TV a soundbar, always go for the one with at least three channels. That is to mean that your choice of soundbar should have three separate speakers that reproduce the audio.

Such a soundbar has a subwoofer and speakers that produce sound upwards and then are reflected to give a theatre-like experience.  For a good experience, consider purchasing soundbars with many channels.

Space Availability

Another great thing to consider when matching your 55 inch TV and a soundbar is space.  Always ensure you have a central place to keep the soundbars. Most soundbars can either be placed above the TV or just below it.

Active Or Passive?

Like speakers, soundbars are either passive or active. Passive soundbars need a separate receiver and a sub-woofer.

This makes it costly and consumes much space in the room and can be complex to set up. On the other hand, active soundbars are compact since they have inbuilt amplifiers and things like channel processors altogether.  They are the most preferred as they help save up space and are easy to set up.

It is recommended that you go for an active soundbar if it is just upgrading your sound system; however, if you want a full-blown Dolby Atmos system, the passive soundbar is the best.

Warranty Services

Did you know that most soundbars have a warranty attached to them? However, for you to enjoy the rights of these warranty services, you have to make the purchasing from an authorized dealer.


Despite your desire for the best soundbar, remember your budget will always dictate. For instance, a 5.1 soundbar is more expensive than a 2.1 soundbar.

Always go for a soundbar that is within your reach such that you can purchase it and also pay electric bills that may arise because of the soundbar consumption.

Can You Use Any Soundbar On Any TV?

As we have already mentioned, the soundbar you choose should not be wider than the TV itself. Choosing a soundbar that is as wide as the TV only adds to the aesthetic value though.

This is because you can technically pair any size soundbar with just about any size TV. It will therefore fully depend on your discretion to choose the right size soundbar that meets the sound and aesthetic requirements of your TV room.

So, finally, what size of soundbar for your 55-inch TV? Since a 55-inch TV has a width of about 47.8 inches, a soundbar with a size of between 40 to 50 inches is suitable.

You can therefore pick a soundbar that is either smaller or larger than 55 inches and still get the best sound delivered from your TV. This is especially true if you are using say a regular short optical cable to connect your soundbar to your TV.

What Is The Difference Between 3.1 And 5.1 Soundbar?

How Do I Match My Soundbar To My TV?

For optimum aesthetics, there must be a size balance between your soundbar and your TV.

A soundbar a couple of inches smaller, bigger or the same width would pair amazingly physically speaking, however, it is really the sound that matters so factors to consider include the space, setup, and arrangement that will provide the most optimized sound experience.

Which Soundbar Is Best For Your TV?
