How Big Of A Sound Bar Do I Need?

Selecting the proper size soundbar to match your TV can be difficult. Soundbars range in dimension from less than a foot long to bigger than some large-screen TVs. Consider the specs before investing in a larger sound bar; bigger sound and more drivers can be found without having to opt for one that is wider or longer.

It's important to note the difference between diagonal TVs and lengthwise soundbars; while a 46-inch wide TV may not match up with a 46-inch wide soundbar, buying an option that is designed by the same manufacturer may help.

If it isn't as important for them to match perfectly, then determining the size of your modern sound bar has been made easier with helpful guides available online that serve as a general guide according to your TV size.

Did you know that to achieve the best results, the soundbar should be 18% of the room length with a maximum distance of 1 foot between the edges of the soundbar and TV?

What Size Sound Bar Do I Need For 50-Inch TV?

If you own a 50-inch TV, like the TCL 50S535, you may feel overwhelmed when choosing a soundbar. The size of your smart sound bar should be approximately 38 to 45 inches, which is not always easy to find.

Ideally, the sound device should not be wider than the actual width of your TV, so keep that in mind while looking for your next audio purchase.

What Size Sound Bar Do I Need For 55-Inch TV?

If you're wondering what size soundbar to get for a 55-inch TV, the answer is quite simple: between 40 to 50 inches. That's because your 55-inch TV has a width of about 47.8 inches and so a sound bar of comparable size should do the trick.

Any variation a few inches smaller or larger is generally accepted, but the best results come from covering at least the base of your TV with the ideal sound bar. So if you're in need of an upgrade, getting one that's around 40 to 50 inches is a great start.

What Size Sound Bar Do I Need For 60-Inch TV?

When it comes to finding the right size sound bar for a 60-inch TV, you want one that is 5 to 10 inches shorter than your TV. So, in this case, the optimal size would be 50 inches long.

This size will ensure the immersive sound bar fits snugly without overpowering the TV or taking up too much space in your living room.

What Size Sound Bar Do I Need For 65-Inch TV?

When deciding on which size sound bar to purchase for your 65-inch TV, the experts recommend buying a rich soundbar between 50 inches to 60 inches. This size will fit perfectly with your TV and provide good coverage for the desired volume and enhanced features that larger sound bars offer.

What Size Sound Bar Do I Need For 75-Inch TV?

When it comes to finding the right size sound bar for your 75-inch TV, there's no need to worry. Any sound bar would be perfectly suited for your flat screen! With a 75-inch screen size, you're unlikely to find a richer sound bar wider than 60 inches that would fit perfectly under or above the TV.

Six Things To Consider When Purchasing The Best Soundbar For You

When buying a room-filling sound bar, there are six factors to consider:

1. Where Will You Put It?

When selecting a sound bar, the first thing you have to consider is where you’ll put it. Different types of sound bars are made with different installation constraints in mind, so just figure out your setup and go from there.

Soundbars generally make for a simpler installation as they can be hung on the wall or placed under (and in front of) your TV. This last option is great if you don’t want any wires visible - just be sure to measure the space between the bottom of your TV and whatever table or credenza it sits on so that you get one that fits comfortably beneath it.

If you have a wall-mounted TV, mounting your sound bar directly under it should be really simple - most come with their own mounting kits that make DIY installation feel like a breeze!

2. What Size Sound Bar Do You Need?

When it comes to selecting the right size sound bar for you, the first thing to consider is how it looks on your TV. Ideally, your sound bar and your television should be roughly the same width so they have a symmetrical design that looks great in any room. However, you can actually pair just about any sound bar with any size television and make it work.

You should also make sure that your TV has the right kind of connection ports to hook up your new sound bar - especially if your TV is 8 years old or older. While you don't need to match the size of your television exactly, be sure the decent SoundBar won't overpower or look disproportionate on top of it either. With these tips in mind, you can confidently pick out the ideal SoundBar for you!

3. What Are Active And Passive Sound Bars, And Why Do They Matter?

When it comes to soundbars, there are two types; active and passive. It pays to know the difference between them when deciding which one is right for you.

Active sound bars come with built-in amplifiers, as well as channel processors that split left right, and center speakers - meaning no extra receiver or additional wires. The only drawback is that the audio quality won’t be as high as with a passive one.

Passive sound bars don’t come with a built-in power amp and will require an amplifier in order to work better. Passive sound bars usually have higher quality speakers, resulting in better sound, but connecting everything may take up more of your time.

4. What Are "Channels" On A Sound Bar, And How Many Do I Need?

When considering what size soundbar to purchase, it is important to understand what channels are and how many you actually need. Channels refer to the speakers or sound sources contained in one unit.

The most common channel setup for sound bars is a 5-channel featuring center, right, left, and two rear speakers. To get a more advanced sound experience, look for a 7-channel sound bar that splits surround and rear channel information into four channels, giving you seven total speakers.

If you're looking for the ultimate home entertainment set up then the Dolby Atmos soundbar might be right for you. This has upward-firing speakers located in the soundbar itself and offers a three-dimensional soundstage suitable for rooms with flat ceilings up to 11 feet high made of reflective material.

5. What Connections Will I Require?

It's important to know what type of connection you'll need when shopping for the best soundbar for you.


The first is an HDMI ARC port, which is great for multi-channel sound bars and easy to connect by connecting your sound bar to your TV’s audio return channel (ARC) input with an HDMI cable.

Wireless Connectivity

You’ll also want a form of wireless connectivity to stream music directly from your sound bar or via your phone or tablet. Bluetooth and Wi-Fi are popular options here, giving you the ability to stream audio easily from any device with either connection.

Optical Port

Optical ports provide a solid and reliable connection with your TV and sound bar but don't have the bandwidth to carry over a 5.1 signal.

USB Inputs

USB inputs can be used to plug in a thumb drive with songs on it, though most sound bars today update through software updates so this isn't needed.

Ultimately, knowing what connections you'll require will help determine which type of sound bar is the best for you.

6. How Do I Operate The Sound Bar?

When you purchase a sound bar for yourself, it is important to consider how you will operate it. Getting a new device may or may not require an additional remote control - it depends on the situation.

You will be given a special remote when purchasing the sound bar, but with some extra research and help, you can set up your existing television remote to control the sound bar too.

This can help simplify how many remotes you have on your coffee table as well as reduce frustration in trying to locate the one for the soundbar. Being able to use one single remote for all of your devices makes enjoying your movie night much easier.

Is It Possible To Add Speakers To A Sound Bar?

It is indeed possible to add dedicated speakers to a soundbar, whether that's through additional speakers within the system itself or through a multi-room audio setup. Many of the newer sound bars that are being released now come with additional speakers which helps to create a much more immersive home theater experience.

If you have (or want to set up) a multi-room audio system in your home, then many sound bars offer the capability to connect wireless rear speakers which can further enhance your movie and music listening experience.

So if you're in the market for an at-home audio system, make sure to look into sound bars that offer this great feature!

Is A Receiver Required If You Have A Sound Bar?

If you are planning to purchase a sound bar for your home, you may be wondering if a receiver is required. The answer is that it depends on the type of sound bar you buy.

If you opt for an active sound bar, then no receiver will be needed - the soundbar itself will provide all the necessary amplification to bring your audio to life.

On the other hand, if you choose a passive sound bar, then yes - a receiver will be necessary in order to power and drive your audio system.

Is It Possible To Add A Subwoofer To A Sound Bar?

For those looking for the ultimate in sound quality, it most definitely is possible to add a subwoofer to a soundbar. While many wireless sound bars come with a wireless subwoofer already included, ones that don't will usually have a woofer port ready for you to plug in your own and enjoy an even more immersive experience.

The addition of a subwoofer will allow you to experience high-quality bass that amplifies your entertainment experience. So if you're looking for more power and performance from your sound bar, adding a subwoofer is definitely something worth considering!

What Exactly Are Dolby Atmos Sound Bars?

When it comes to soundbars, newer models come with innovative Dolby Atmos technology. This special feature allows users to enjoy an immersive surround sound system in their own homes. With Dolby Atmos audio bouncing off the ceiling and walls, you can recreate the sensation of a real theater in your living room.

The technology is designed to simulate multiple speakers in one unit, providing a 360-degree soundscape that wraps around you. And while it's not quite as comprehensive as a full virtual surround sound setup, it still provides an impressive result.

What Is "Cinema Sound"?

Cinema Sound is basically a digital delay that's added to the soundbar. This creates an effect similar to reverb, making it seem like you're in a larger space or room. While this doesn't quite provide the same level of actual home theater sound, it can still give the illusion that your audio is coming from more sources than just the soundbar.

It is important to remember that certain models are more advanced than others, and you may need to pay additional fees for features like these.
