Best Soundbars for TV: UK Buying Guide

The best soundbar for your TV in 60 seconds

If you want the short answer, start with your TV, not the soundbar. Look at the back of the set for a socket labelled HDMI eARC or HDMI ARC. If it is there, buy a bar that connects over HDMI, because you get one cable, one remote and the best sound formats. If you only see an optical socket, any bar with an optical input will work, but skip paying extra for Dolby Atmos because optical cannot carry it.

Next, think about what you watch. For news, soaps and dramas, a compact bar with a dedicated centre channel does more for dialogue than a big bass box. For films, football and gaming, a bar with a wireless subwoofer is the upgrade you will notice every evening.

• Small room or bedroom: compact 2.0 or 2.1 bar
• Struggling to hear speech: 3.0 or 3.1 bar with a centre channel and a voice mode
• Films and sport in an average lounge: 3.1 with a wireless subwoofer
• Proper home cinema with a flat ceiling: 5.1.2 or higher with Atmos and rear speakers

Matching a soundbar to your TV brand

Any modern soundbar will work with any modern TV over HDMI ARC, thanks to the HDMI-CEC standard that lets the TV remote control the bar. Buying the same brand as your TV can add a few extras, though, and it is worth knowing what they are before you pay for them.

Samsung TVs offer Q-Symphony, which lets a compatible Samsung soundbar play alongside the TV's own speakers for a wider sound. LG has a similar feature called WOW Orchestra, and Sony's Acoustic Center Sync uses certain Bravia TVs as a centre speaker for a matching Sony bar. These are nice touches, not essentials. If a different brand suits your room or budget better, it will still connect and work with your TV remote.

Whatever brand you choose, switch on HDMI-CEC in the TV settings. Each manufacturer gives it a different name — Anynet+ on Samsung, SimpLink on LG, Bravia Sync on Sony — and it is the setting that makes volume control through one remote work.

Clearer dialogue: the most common reason to buy

The complaint I hear most is not about bass, it is about not being able to make out what people are saying. Thin TVs fire their speakers downwards or backwards, so speech bounces off the furniture before it reaches you. A soundbar points its drivers straight at the sofa, which helps straight away.

If speech is your main problem, look for two things: a dedicated centre channel (the middle number in 3.1 or 5.1) and a dialogue or voice enhancement mode. Together they lift the voice frequencies above the music and effects, so you can stop riding the volume up and down through every film.

What the channel numbers mean

Every soundbar is described with a figure like 2.0, 2.1, 3.1 or 5.1.2. The first number is how many main speaker channels the bar drives, the second is the number of subwoofers, and the third — when it exists — is the number of upward-firing height drivers used for Dolby Atmos.

In practice, a 2.0 bar is a straight swap for TV speakers. A 2.1 or 3.1 adds a subwoofer and, on the 3.1, a dedicated centre channel that makes dialogue much easier to follow. Anything with a third digit is trying to bounce height effects off your ceiling, which only works if that ceiling is flat, hard and roughly two and a half to three metres up.

• 2.0 — compact, no separate sub, best for bedrooms and small lounges
• 2.1 / 3.1 — wireless subwoofer added; the 3.1 centre channel sharpens speech
• 5.1 — adds rear surround speakers, needs cabling or wireless rears and space behind the sofa
• 5.1.2 and above — adds Atmos height channels, dependent on ceiling shape

Connections: use HDMI eARC where you can

There are three realistic ways to connect a bar. HDMI eARC is the best of them: it carries lossless and object-based formats, passes volume control through your TV remote, and needs a single cable. HDMI ARC is the older version of the same idea and handles compressed Dolby Digital fine, but not the full-fat lossless streams.

Optical is the reliable fallback on older televisions. It carries stereo and Dolby Digital, but it cannot pass Atmos and it will not relay remote volume commands, so you end up juggling two remotes. Bluetooth is convenient for music from a phone but adds latency, which puts lip-sync out on video.

Do you need the subwoofer?

If you mostly watch news, drama and daytime television, a well-tuned bar without a sub is enough and it saves you a box on the floor. If you watch action films, follow live sport, or play games with a lot of low-end effects, a subwoofer changes the experience far more than another hundred pounds spent on the bar itself.

Wireless subs are not truly wireless — they still need mains power — so plan a socket within a few metres of a corner or a wall you can place the sub against. Corner placement raises perceived output, which is useful in a big room and a nuisance in a small flat.

Sizing the bar to the room and the TV

As a rule of thumb, the bar should be no wider than the television it sits under, and ideally within about 15cm of the screen width so it looks intentional. Check the height too: a tall bar in front of a low-standing TV can clip the bottom of the picture or block the infrared receiver.

Room size matters more than raw wattage. A small room excites bass easily and a big bar will boom; a large open-plan space needs the extra drivers and the sub to fill it. Wattage figures are quoted inconsistently across brands, so treat them as marketing rather than a comparison tool.

Soundbar setups by room and use

Buying checklist

• Confirm your TV has HDMI eARC, HDMI ARC or optical, and buy to match
• Measure the TV stand width and the gap under the screen before ordering
• Decide early whether you want a subwoofer — retrofitting is rarely possible
• Only pay for Atmos height channels if your ceiling is flat and hard
• Check the bar supports your TV remote's volume control to avoid two-remote living

Frequently asked questions

Is a soundbar better than TV speakers?

Almost always, yes. Modern televisions are too thin to house speakers with any cabinet volume, so they struggle with bass and dialogue. Even an entry-level soundbar has forward-facing drivers and a proper enclosure, which improves speech clarity immediately.

Do I need a subwoofer with a soundbar?

Not for everyday television. For films, games and sport a subwoofer makes a bigger difference than any other single upgrade, because it covers the low frequencies a slim bar physically cannot reproduce.

HDMI ARC or optical — which should I use?

Use HDMI ARC or eARC if your television offers it. It carries more audio formats and lets the TV remote control the bar's volume. Optical is a solid fallback but cannot pass Dolby Atmos.

Will a soundbar work with any television?

Yes. Any TV made in the last fifteen years has at least an optical or 3.5mm output, and most have HDMI ARC. The only thing to check is which socket you have free.

Does Dolby Atmos work in every room?

No. Upward-firing Atmos drivers bounce sound off the ceiling, so sloped, beamed, very high or soft ceilings scatter the effect. In those rooms a good 3.1 system usually sounds better than a compromised Atmos one.

Should the soundbar sit above or below the TV?

Below, at roughly ear height when you are seated, with nothing blocking the front of the drivers. If it is wall mounted, keep it close under the screen so dialogue appears to come from the picture.

What is the best soundbar for my TV?

The best soundbar for your TV is one that matches its connection and your room. If your TV has HDMI eARC or ARC, choose a bar that connects over HDMI. Pick a 3.1 bar if dialogue is the issue, add a wireless subwoofer for films and sport, and only pay for Atmos if your ceiling is flat.

Do I need the same brand of soundbar as my TV?

No. Any HDMI ARC soundbar works with any HDMI ARC television. Matching brands unlocks extras such as Samsung Q-Symphony, LG WOW Orchestra or Sony Acoustic Center Sync, but the core sound and remote control work across brands.
