How to Improve TV Sound: The One Upgrade That Changes Everything

3 mins read
Since sound was first added to film in 1927, artists and engineers have continually found ways to enhance and elevate scenes with Foley, music and more, from atmospheric soundtracks to pivotal dialogue delivery. So, why would you not experience your TV sound at its very greatest? With a soundbar, you can.

A high-performance soundbar is the engineered solution to restore lost detail and emotional impact in one elegant unit. But how exactly does a soundbar achieve this? This blog will explore how a soundbar elevates your TV experience, from improving dialogue clarity and delivering powerful bass, to creating a truly immersive soundscape for movies and gaming.

How Do Soundbars Work With a TV?

Soundbars are a single unit containing multidirectional speakers that project TV audio into a space at all angles. This creates a feeling of sound coming from the sides, behind, and front, positioning you as though you were physically in the on-screen action.

They are best connected to a television with an HDMI cable, as these cables can carry large amounts of uncompressed data, including Dolby Atmos systems. Simply connect through the HDMI-ARC ports on both your soundbar and television.

If your TV doesn’t have HDMI-ARC, an optical cable or AUX will also serve as a strong connector.

How Soundbars Improve Audio Detail

With multiple components in a single unit, your soundbar can give each frequency in a TV soundscape the attention it deserves. Tweeters bring high-pitched whistle tones to life, midrange drivers make each line of dialogue stand out, and woofers help bass sounds to boom. From the emotion of the speech, to the whistle of the wind, the rush of a river, to the zoom of a vehicle, you’ll hear it all.

How Soundbars Improve Dialogue Clarity

The centre channel speaker of your soundbar is dedicated to accurate dialogue reproduction, ensuring the sound seems as though it’s coming directly from the actors’ mouths.

As if that weren’t enough, voice enhancement modes have also been specially developed to bring out dialogue. Now you can finally catch that oddly mumbled line or understand that subtle whisper without a thousand rewinds.

How Soundbars Improve Bass

KEF’s XIO soundbar contains four class D low-frequency drivers for those deep, deep sounds like roars, explosions, thunder and more. But if you crave even deeper bass, you can connect your soundbar to a subwoofer.

How Soundbars Improve Immersion

As a multidirectional speaker, soundbars can make audio seem like it’s coming from every angle, helping you feel as though you are at the very centre of the scene. This can be further enhanced with Dolby Atmos, which also brings overhead sound into the equation.

KEF’s XIO Soundbar provides Dolby Atmos 5.1.2 spatial audio - the equivalent of five surround sound speakers and two overhead speakers in a single unit.

How Soundbars Improve Gaming

The surround sound of a soundbar brings you into the excitement of the game with stunning realism, as Dolby Atmos positions each sound in space exactly as it would be in the scene. Perfect for group gaming sessions, experiencing the audio and the gameplay together.
