Buying a soundbar: how to find the right sound for your TV and home cinema

A TV can deliver a sharp picture and still sound thin, quiet or difficult to understand. The right soundbar can improve your TV’s sound without the need for an AV receiver and large speakers. However, technical terms and high wattage figures don’t automatically mean a system is right for you.

Common soundbar buying pitfalls

1. Confusing wattage with sound quality

The maximum power output mainly indicates potential volume and amplifier headroom. It doesn’t automatically tell you how clear dialogue will sound, how strong the bass is or how immersive the audio will be. You should also consider:

  • the number and layout of the speakers
  • whether there’s a separate or built-in subwoofer
  • the audio formats supported
  • the size of the room and your listening distance
  • the available volume and sound controls

A compact 2.0 soundbar may be a better choice for a bedroom than a large system whose speakers have nowhere suitable to go in your living room.

2. ‘Dolby Atmos’ doesn’t always mean genuine overhead sound

A Dolby Atmos soundbar can process Atmos signals. However, the speaker layout, ceiling height and finish, and the source material all play a part in creating a noticeable sense of height. Up-firing speakers need a reasonably flat, even ceiling. Virtual surround technologies, on the other hand, use signal processing and often work without additional speakers.

So consider whether you want a soundbar with separate surround speakers, a virtual surround system or a combination of the two.

3. Checking the connections only after buying

A TV with HDMI ARC isn’t automatically compatible with every soundbar feature. HDMI eARC is useful for certain multichannel and Atmos signals. Also check:

  • Does your TV have HDMI ARC or HDMI eARC?
  • Is an HDMI cable included?
  • Is there an optical input as an alternative?
  • Do you need HDMI passthrough for a games console or Blu-ray player?
  • Is Bluetooth intended only for music streaming, or for other devices too?

The key technical features

Understanding channel numbers

2.0 means two main channels with no separate subwoofer. 2.1 adds a bass channel or subwoofer. In a 5.1 soundbar, the first number represents the front channels, the second the bass channel and the third the surround channels. A 7.1 soundbar may offer additional surround channels or corresponding signal processing.

However, the channel count is only useful if you know whether the system has physical speakers. A system with four separate surround speakers will generally distribute sound around the room differently from a single bar using virtual surround sound.

Subwoofer: wireless or built-in

A soundbar with a subwoofer can handle low frequencies more effectively. A wireless subwoofer still needs its own mains socket, but gives you more flexibility over where to place it. A built-in subwoofer saves space and cables, although very compact enclosures may have less room for the speaker.

A separate subwoofer is often a good choice for films, games and bass-heavy music. In smaller rooms, or if you have neighbours close by, a compact soundbar without powerful bass may be more practical.

HDMI ARC and HDMI eARC

HDMI ARC sends your TV’s audio through a single HDMI cable and, with compatible devices, lets you control the volume using your TV remote. HDMI eARC offers greater bandwidth and is better suited to higher-quality multichannel formats, including certain Dolby Atmos signals.

Check the specifications for both your TV and soundbar. You may also need to set the TV’s audio output in the menu to Bitstream, Passthrough or a compatible format.

Practical tips for set-up and use

Place the soundbar as centrally as possible beneath your TV. Make sure furniture or the TV stand doesn’t block the centre channel. If you’re mounting it on a wall, check that the bracket, wall material and cable routing are all suitable. A subwoofer can sound different depending on where it’s placed in the room, so try a few locations without blocking its ventilation openings.

With surround speakers, place the side or rear units roughly level with your listening position. Route cables safely to avoid trip hazards, and keep small accessories out of children’s reach. Keep the volume moderate, especially during long gaming or film sessions.

Frequently asked questions about soundbars

Which soundbar is right for a TV?

For a straightforward improvement in sound, a 2.0 or 2.1 soundbar with HDMI ARC is often enough. If you watch films or play games with surround sound, check for HDMI eARC, Dolby Atmos and the speaker layout you want.

How long does a soundbar last?

Its lifespan depends on how it’s used, ventilation, volume levels and power supply. Keeping it in a dry, well-ventilated place and installing regular firmware updates can help it work reliably. For wireless components, you should also consider the wireless range and the location of power sockets.

Does a wireless soundbar use a lot of electricity?

A wireless soundbar and a wireless subwoofer each need their own power supply. In standby, their power consumption is usually much lower than when they’re in use. You can find the specific figures on the energy label, in the product data sheet or in the user manual for the model.
