Kinds of soundbar
- All-in-one: one bar beneath the TV and nothing else to position. The easiest upgrade, and the neatest in a bedroom or small lounge.
- Bar with subwoofer: the bar looks after voices and detail, and a separate wireless sub supplies the low end.
- Dolby Atmos bars: upward-firing speakers bounce sound off the ceiling for a sense of height in films and games. Available all-in-one or with a sub.
- Bars with rear speakers: bar, sub and wireless speakers behind you, for real surround without cables across the floor.
Which soundbar suits you?
| Type | Suits | Worth checking |
| All-in-one | Bedrooms, kitchens and smaller lounges. | Width against the TV, and a dialogue mode. |
| With subwoofer | Films, sport and music with real weight. | Floor space and a socket for the sub. |
| Dolby Atmos | Film fans with a normal, flat ceiling. | Upward-firing drivers and eARC on your TV. |
| With rears | Proper surround without a receiver. | Sockets and space behind your seats. |
Making the choice
What the numbers mean
Soundbars are labelled 2.0, 3.1, 5.1.2 and so on. The first figure counts main channels: two for stereo, three adding a centre for dialogue, five or more for surround. The second shows whether a subwoofer comes with it (1) or not (0). A third figure, where there is one, counts the height channels for Dolby Atmos.
Hearing the dialogue
If mumbled speech is the main complaint, look for a dedicated centre channel, meaning a first figure of three or more. A speech-enhancing mode, found on many bars, helps too.
Bass
Nothing transforms films, sport and music like a sub. The connection to the bar is wireless, though it still takes up floor space and a power point. Living in a flat or a terrace? Stick to a bar without a sub, or use night mode, and the neighbours will thank you.
Atmos and surround
Atmos relies on sound reflecting off the ceiling, so a flat ceiling of ordinary height works best. You'll also need something to watch in Atmos, and the major streaming platforms offer lots. For sound genuinely behind you, choose a system with rears.
Connections
Wherever possible, connect by HDMI ARC or eARC: one cable, and the TV remote controls the volume. Simpler bars may use an optical cable. Bluetooth plays music from your phone; Wi-Fi adds streaming, voice assistants and, on some, multi-room.
Pairing with your TV
Some bars team up with the same brand's TVs, using the TV's own speakers alongside the bar, with a single remote and on-screen menu for both. Worth a look if you're buying both; see our TVs.
Before you order
- Measure the width. About the width of the TV, or a little less, looks right. Check it fits between the TV's feet.
- Check the height. On a unit, it mustn't cover the bottom of the screen or the remote sensor.
- Wall mounting? Many bars can hang below the TV; see whether a bracket is included.
- Find the ARC or eARC socket, labelled on the back of the TV.
- Count the sockets. The bar, sub and each rear usually need their own.
Other ways to listen: home cinema, wireless speakers and headphones, or all of audio and home cinema.

Soundbars: your questions answered
Is a soundbar worth buying?
For most TVs, yes. There's not much space for speakers in a thin screen, so speech often sounds weak. Even a basic bar brings clearer dialogue and fuller sound.
What do numbers like 3.1.2 mean?
Main channels, then subwoofer, then height channels for Atmos. A 3.1.2 bar has three front channels, one sub and two height channels.
Do I need a subwoofer?
Not for everyday TV. For regular film nights, live sport or music, a sub fills in the low notes that a bar on its own can't reach.
Will a soundbar work with my TV?
Almost certainly. If the TV has an optical output, or an HDMI socket marked ARC or eARC, you're set. Compare the bar's connections with your TV's sockets.
Does Dolby Atmos need a special TV?
The TV has to send Atmos on to the bar; most recent models do this through their ARC or eARC socket. You'll also need programmes or films made in Atmos.
Can I play music through a soundbar?
Yes. Most have Bluetooth for your phone or tablet, and Wi-Fi models can stream directly.
