What is a sound bar?

Amplify your TV’s sound with a low profile, big audio sound bar.

23 Apr 2021

Connecting a sound bar is the easiest way of improving the sound on your TV. They take up very little space and are really easy to set up. Sound-wise, they’re much better than TV speakers. And with the addition of a subwoofer, you can experience the full audio experience just like at the cinema.


Sound bar and home cinema – what’s the difference?

A sound bar is a slim, oblong-shaped device that contains several individual speakers placed side by side. It can be mounted on the wall beneath your TV or placed flat on your TV stand in front of your telly. It connects to your TV via a single cable so there aren’t loads of trailing wires to worry about.

With home cinema systems, each speaker is housed in its own separate unit and positioned around the room, with cables trailing back to the TV. They offer amazing audio, but you’ll have to figure the best solution to keep wires out of the way.

Home cinema delivers true surround sound, while a soundbar offers improved audio with virtual surround sound – without all the wires and separate speakers.


How does it improve my TV’s sound?

As modern LED, OLED and QLED TVs have become slimmer, the space for speakers inside them has shrunk. Naturally this has led to smaller built-in speakers on our TVs.

Stereo sound is divided between 2 channels – one to the left, the other to the right. Most TV shows are recorded with this type of sound. With speakers to the left and right, a soundbar creates perfect stereo sound.

If you want to feel the rumble of big budget battle scenes, or the atmosphere of the stadium on match day, go for a model with a separate subwoofer. The subwoofer handles all the low-frequency sounds that other speakers can’t, giving you the full range of audio as the sound designers intended. Wireless subwoofers can be placed anywhere in the room for the ultimate movie night experience (right by the sofa is always a good bet).


Buying a soundbar – things to look out for:


External subwoofer

The subwoofer can either be built into the soundbar or housed in a separate unit. If you opt for a separate subwoofer, consider a wireless one so you won’t have a cable trailing from your soundbar to your subwoofer.


Dolby Atmos

This clever technology combines object tracking sound with upfiring speakers. Instead of the speakers facing towards your viewing area, the multi-directional design makes sound feel as if it’s all around you. And because the sound follows the action on screen, it makes whatever you watch even more immersive and realistic. Whether you’re an F1 fan or love a trending drama, Dolby Atmos brings serious virtual surround sound skills to the party.


Bluetooth for music

Sound bars can be as great for music as they are for TV. If you want to switch between an episode on Netflix, to a playlist on Spotify, opt for a model with built-in Bluetooth. Then you’ll be able to listen to music on your phone or tablet through the soundbar. The same goes for music stored on your phone, tablet or laptop.


Voice control

Many sound bars double up as smart speakers. With voice assistants like Google Assistant and Amazon Alexa built-in, there’s no limit to what your sound bar can do. Set reminders, plan your schedule, request a tune by asking or hear the latest news. You can even link up your smart lights, thermostat, and appliances and control them all from the comfort of your living room.



Want to keep hearing the song as you move from room to room? Some sound bars can be connected to wireless multi-room systems – where different speakers are dotted around the house. These speakers are all controlled from a single app, and can be used to play different or the same music. So you can either link it up to your music system or create your own true cinema surround-sound system.


HDMI 4K passthrough

Only got a limited number of inputs on the back of your TV? Not a problem. Some sound bars that connect to TVs via HDMI have a feature called 4K passthrough. That means you can plug your games console, Blu-Ray player or digital TV box into the sound bar, plug the sound bar into the TV, and it can display whatever’s linked to your sound bar in true 4K quality. All without the spaghetti-like mess of cables.


Great audio to get you started
