Buy a Dolby Atmos soundbar: what to consider when choosing and setting it up

A Dolby Atmos soundbar can reproduce TV audio with a more spacious and detailed sound than many built-in TV speakers. However, the Dolby Atmos logo alone does not determine whether a soundbar is suitable. Room size, speaker layout, connections and the audio format actually being played all have a major impact on the result.

If you only look at wattage or a high channel count when buying, you may end up with a product that does not suit your needs. Three common pitfalls are particularly important:

  • Dolby Atmos is not always transmitted natively: A TV with a basic HDMI-ARC connection or an incompatible streaming device may limit the signal. For uncompressed multi-channel formats, HDMI eARC is often the more suitable interface.
  • High wattage is not a direct comparison of sound quality: Manufacturers sometimes use different specifications, such as peak power or total power. Room acoustics, drivers, tuning and positioning cannot be reliably inferred from these figures.
  • Multiple speakers require space and power: A 7.1 soundbar with rear speakers can create a wider surround effect, but it also needs additional surfaces, power sockets and safe cable routing. For small living rooms, a compact 2.1 or 3.1.2 solution may be more practical.

The most important buying criteria for a Dolby Atmos soundbar

1. Check the connection and audio format

The connection is crucial for a TV soundbar. HDMI eARC supports greater bandwidth than conventional ARC and, depending on the TV, source and settings, can transmit suitable Dolby Atmos signals. Check the following before buying:

  • Does the TV have HDMI ARC or HDMI eARC?
  • Does the streaming device, games console or Blu-ray player support the desired audio format?
  • Is an HDMI input on the soundbar or HDMI passthrough for external devices required?
  • Would an optical input, USB or AUX connection also be useful?

A Bluetooth soundbar is suitable for playing music from a smartphone or tablet. However, Bluetooth does not automatically replace a wired connection for transmitting a multi-channel audio signal from the TV.

2. Understand channel configurations and speaker layouts

Figures such as 2.1, 5.1, 7.1 or 5.1.2 describe the speaker channels. Simplified, the first number represents the main channels and the second represents the subwoofer. The third number in 5.1.2 refers to additional height channels, often provided by upward-firing drivers.

A 5.1 soundbar with physical rear speakers distributes effects differently from a compact surround soundbar that uses virtual surround processing. Upward-firing speakers can benefit from a low ceiling and a suitable seating position. In very open-plan rooms or rooms with sloped ceilings, the Atmos effect may be less pronounced.

3. Consider the subwoofer, rear speakers and positioning

A soundbar with subwoofer can emphasise low frequencies more strongly than an all-in-one model. A wireless subwoofer reduces the number of audio cables, but it still requires a power socket. Avoid placing it directly in a confined corner if this causes booming sound.

With a soundbar with rear speakers, the additional speakers should be positioned to the sides of or behind the seating position. Cables must not create trip hazards. Wall mounts must be suitable for the wall construction and the weight of the equipment. Do not cover the ventilation openings of the devices.

Setup: how to avoid common sound problems

Where possible, connect the soundbar via the appropriate HDMI ARC or HDMI eARC connection. Activate external audio output on the TV and, if available, select Bitstream, Passthrough or the relevant Dolby audio setting. The exact name depends on the TV model.

Position the soundbar centrally below the screen. It should not be obstructed by the TV stand or a shelf. Rear speakers should be positioned roughly at ear height or slightly above. After automatic room calibration, it is worth checking the dialogue and surround volume levels, as highly reflective or open-plan rooms can affect how the sound is perceived.

Dolby Atmos soundbar FAQ

Do I definitely need HDMI eARC for Dolby Atmos?

Not necessarily. Depending on the TV and audio source, Dolby Atmos may also work via other connections. However, HDMI eARC offers greater transmission bandwidth and is usually the more suitable connection for compatible, high-resolution multi-channel signals. Always check the specifications of the TV, source device and soundbar.

How long does a soundbar usually last?

Service life depends on operating hours, heat generation, volume, firmware maintenance and mechanical stress. Good ventilation, secure positioning and use of the intended power supply help reduce avoidable strain. With a system featuring a wireless subwoofer and rear speakers, you should also check the power connections and wireless pairing regularly.

Does a soundbar with a subwoofer use a lot of electricity?

Power consumption depends on the model and how it is used. The soundbar, subwoofer and rear speakers may each have their own standby or operating figures. If you want to save energy, use automatic switch-off, fully turn off devices you are not using and compare the manufacturer’s technical power-consumption figures before buying.
