Soundbar buying guide for clearer TV audio in any room

Modern TVs look great but often sound thin and weak. A soundbar is one of the simplest upgrades you can add, and there are options for almost every room size and budget.

This guide walks through the main types, features that matter, and practical tips so you can pick a soundbar that fits your space and habits without paying for things you will never use.

Decide what you want to improve first

Before comparing models, be clear about your main problem with your current TV audio. Do you struggle to hear dialogue, want more impactful bass for movies, or just need better sound in a small flat without shaking the walls?

Prioritising your main goal helps you avoid overpaying. For example, if speech clarity is the issue, you might not need a big subwoofer, while film fans might care less about compact size and more about immersive surround formats.

One-piece bars vs bars with subwoofers and rear speakers

Most soundbars fall into three broad groups, each with different pros and cons.

• All-in-one bars:Just the bar, no separate subwoofer or rear speakers. They save space and are easier to place, and many midrange models now deliver decent bass for news, shows and casual films. They suit bedrooms and smaller living rooms.
• Bar plus subwoofer:A separate subwoofer adds low-frequency impact for action scenes and music. This style is very common in living rooms and home cinemas. Check where you can place the subwoofer, since it still needs a nearby power socket.
• Full surround sets:Bar, subwoofer and rear speakers. These provide the most immersive effect for surround sound formats but require more cables or at least extra power outlets and careful placement.

If you live in a flat with thin walls, an all-in-one bar or a bar with a smaller, adjustable subwoofer can give a big improvement without upsetting neighbours.

Match the soundbar to your room size and TV

Room size and layout affect which soundbar makes sense. In a compact room with the sofa close to the TV, a modest bar with a subwoofer can feel very full. In a long or open-plan space, you may benefit from a more powerful model with larger drivers.

Check the width of the bar too. Ideally it should not be wider than your TV stand or much narrower than the TV itself. Make sure the bar will not block the TV’s infrared sensor or bottom edge of the picture if you place it in front of the screen.

Connections that keep setup simple

Most people will connect a soundbar to the TV with HDMI, but the details matter.

• HDMI ARC or eARC:This single cable links TV and soundbar and lets you control volume with the TV remote. ARC supports standard formats, while eARC has more bandwidth for high-quality Dolby Atmos and DTS:X. If your TV has eARC, it is worth picking a bar that supports it.
• Optical input:Useful for older TVs without ARC. It carries digital audio but not the most advanced surround formats, and you usually need a separate remote for the bar.
• HDMI inputs on the bar:Some models include extra HDMI ports so you can plug devices like consoles or media players directly into the soundbar. This can simplify cabling but is less essential if your TV already has enough HDMI ports.

Check the back of your TV for available connections before you buy, especially if it is more than a few years old.

Understanding Dolby Atmos and virtual surround

Many midrange and premium soundbars promote Dolby Atmos or DTS:X, which are surround formats that can place sound above and around you. Bars that support them use either upward-firing speakers or digital processing that simulates height and surround channels.

Upward-firing speakers work best in rooms with a flat, reflective ceiling that is not too high. If you have a very high or sloped ceiling, a bar that relies on virtual surround processing may give more consistent results. These models can still improve immersion compared to plain stereo, though not as dramatically as a full speaker system.

Features that really improve daily use

Beyond sound quality, some features can make a big difference to how pleasant a soundbar is to live with.

• Dialogue enhancement:A mode or separate centre channel that makes voices louder and clearer, especially helpful for news and drama.
• Night mode:Compresses loud sounds and boosts quieter ones so you can watch late without sudden explosions waking others.
• Adjustable subwoofer level:Lets you turn bass up for films or down for late-night viewing and apartments.
• Auto power-on and TV remote learning:So the bar wakes when the TV does and responds to your existing remote’s volume buttons.

Streaming features, such as Bluetooth, AirPlay or Chromecast built-in, are helpful if you want to play music or podcasts through the bar when the TV is off.

Budget ranges and what to expect

Prices vary widely, but you can roughly group soundbars into three tiers.

• Entry-level:Basic bars or bar-plus-sub combos, usually with HDMI ARC and Bluetooth. Ideal if you just want clearer sound than the TV and have a limited budget.
• Midrange:Better drivers, more refined tuning and often Dolby Atmos support, plus stronger build quality and more inputs. Good balance for most living rooms.
• Premium:More channels, upward-firing speakers, powerful subwoofers and extensive app control or multiroom features. Worth it if film and series are a major hobby and you have a suitable room.

Always factor in potential extras, such as wall-mount brackets, HDMI cables or rear speaker add-ons, which may not be included in the base price.

Practical placement and setup tips

Plan where the bar and subwoofer will go before you commit. The bar should sit close to ear level when you are seated or be angled towards you if mounted lower. Avoid pushing it right back into a cabinet, since that can muffle the sound.

A subwoofer does not have to sit under the TV, but it should be on the floor and not trapped inside a closed cupboard. After everything is connected, spend a few minutes adjusting sound modes, bass level and dialogue settings for your preferred content, then save those as presets if the bar allows it.

How to narrow down your shortlist

When you have a few candidates, compare them on three main points: connection compatibility with your TV, room and size fit, and your top-priority features like dialogue enhancement or Atmos. Only then look at brand ecosystems, app control and design style.

This way, you end up with a soundbar that works reliably with your existing setup, fits your room without hassle and genuinely improves the way you watch and listen, instead of just packing in extra logos on the box.
