Soundbars for TV: buying advice, connection checklist and models to suit you

A slim television doesn’t automatically need a weak audio setup. In practice, however, wattage and terms such as Dolby Atmos aren’t the only factors that determine whether a soundbar for your TV is right for your living room. Room size, connection standards, speaker placement and how you plan to use it are just as important.

If you focus only on high power ratings, it’s easy to overlook important details. The buying criteria below will help you see past the marketing claims and choose a home cinema sound system that suits you.

Common pitfalls when buying a TV soundbar

1. Higher wattage is assumed to mean better sound

Maximum or so-called peak power doesn’t automatically indicate the volume you can sustain or the sound quality you’ll get. The speaker configuration, number of channels, frequency range and whether there’s a subwoofer are more useful indicators. A compact 2.1 system may be a better choice for a small room than a more powerful multi-channel system that’s difficult to position properly.

2. Dolby Atmos doesn’t work the same way with every connection

A Dolby Atmos soundbar needs a compatible source and a suitable signal path. HDMI ARC and HDMI eARC differ in the bandwidth they can support. For certain high-resolution and multi-channel audio formats, HDMI eARC is the more suitable connection. Older TVs, on the other hand, may only be able to transmit Dolby Digital or another compressed format.

3. ‘Wireless’ doesn’t mean completely cable-free

With a wireless soundbar, the subwoofer or rear speakers may connect to the soundbar wirelessly, but they’ll usually still need a power supply. For wired surround speakers, you’ll also need to consider cable lengths, socket positions and potential trip hazards.

The most important buying criteria

Connections and TV compatibility

Start by checking the connections on your TV:

  • HDMI ARC: Handy for controlling the volume with your TV remote and making a simple one-cable connection.
  • HDMI eARC: Offers greater audio bandwidth and is better suited to many higher-quality multi-channel formats.
  • Optical input: Works with older TVs, but doesn’t support every modern audio feature.
  • Bluetooth: Useful for playing music from your mobile phone or tablet. Depending on your TV, audio transmission may be delayed.
  • USB and AUX: Handy for connecting certain media players, computers or older devices.

You should also select the right audio output in your TV’s settings. With HDMI ARC or eARC, you may also need to enable HDMI-CEC and choose the correct audio format, depending on the model.

Channel setup, subwoofer and room size

A 2.1 soundbar typically consists of two main channels and a subwoofer. It’s a good choice if you want to improve your TV’s sound and keep installation straightforward. A soundbar with a subwoofer has a dedicated bass channel, which can add depth to film soundtracks, music and games.

A 5.1 soundbar or 7.1 soundbar adds further centre and surround channels. This can be beneficial in a larger seating area, but you’ll need enough space for the speakers. Virtual surround technologies create a sense of space through signal processing; separate rear speakers, by contrast, use physical sound sources positioned behind you.

Placement and dimensions

Measure the space beneath your TV. The soundbar shouldn’t cover the TV’s infrared sensor or block any ventilation openings. If you’re wall-mounting it, consider the brackets, wall material and cable routing.

The subwoofer shouldn’t be placed inside a closed cabinet. If you have rear speakers, check whether your seating position allows you to arrange them effectively. Automatic room correction can be helpful, but it’s no substitute for getting the basic placement right.

Installation and day-to-day use

Where possible, connect the soundbar via HDMI ARC or eARC if your TV has the right port. Then select the appropriate digital audio output in your TV’s settings. With an optical connection, the output may be limited to PCM or a compatible compressed format, depending on the device.

For reliable operation, make sure the speakers, subwoofer and power supplies have enough ventilation. Arrange cables to avoid trip hazards. Power consumption varies by model, volume level and standby mode. If your devices stay plugged in, low standby power consumption can help reduce running costs.

TV soundbar FAQs

Which soundbar is right for an older TV?

A soundbar with an optical input, AUX or HDMI ARC is usually suitable for older TVs. Before buying, check which connections are actually available and whether your TV remote supports volume control.

Is a soundbar with a subwoofer a good choice for a small room?

Yes, as long as the subwoofer has space around it and isn’t placed inside a closed piece of furniture. A 2.1 system is often enough for a small room. A larger 5.1 or 7.1 system needs more space and a suitable seating position.

What matters more for gaming: Dolby Atmos or low latency?

They serve different purposes. Dolby Atmos can create a more spacious listening experience, while low latency helps keep the picture and sound in sync. For consoles and PCs, you should also check the HDMI version, passthrough support and your TV’s connections.
