Soundbar for TV: The right solution for clear sound and greater home cinema comfort

A TV can deliver a large, sharp picture and still sound thin during dialogue, music or film scenes. A soundbar for TV usually improves the sound while taking up less space than a traditional speaker set-up. However, a high wattage does not automatically guarantee the right result. Connections, speaker channels, room size and how you intend to use it are what really matter.

Common buying mistakes when choosing a soundbar for TV

1. Confusing wattage with sound quality

Manufacturers often quote the maximum or so-called peak power. This figure does not necessarily indicate the continuously usable volume or the balance of the sound. When choosing, you should also consider driver size, channel configuration, frequency range and subwoofer design.

A compact 2.1 soundbar can be a sensible choice for news, TV series and smaller rooms. A larger home cinema sound system with several surround speakers, on the other hand, needs more floor space and careful positioning.

2. Expecting Dolby Atmos without the right room and connection conditions

A Dolby Atmos soundbar can process compatible audio formats. However, the result you perceive depends on the ceiling height, seating position, reflective surfaces and source material. If the speakers fire upwards, the ceiling should ideally not be highly angular or covered with sound-absorbing materials.

You should also check whether your TV has an HDMI eARC connection. This is the only way to use certain high-resolution audio formats and convenient control via a single HDMI cable. An optical connection remains practical, but it does not support the same transmission options as eARC.

3. Equating “wireless” with a completely wireless installation

A wireless subwoofer transmits the audio signal without a speaker cable. However, it still needs a mains socket. Additional speakers in surround systems may also require power or connection cables. Before buying, you should therefore plan for available sockets, cable lengths and the position behind the sofa.

Technical specifications to check before buying

Channel count and speaker configuration

The channel designation describes how the audio channels are arranged:

  • 2.1 soundbar: two main channels plus a subwoofer, suitable for smaller rooms and a straightforward installation.
  • 5.1.2 soundbar: five main channels, one subwoofer channel and two height channels, often combined with Dolby Atmos.
  • 7.1 soundbar: multiple front and surround channels for wider sound distribution.
  • Soundbar with subwoofer: a sensible choice if you want deeper frequencies to be more prominent in films, music and gaming.

More channels do not automatically mean a more suitable solution. In a small living room, additional speakers can make the set-up more complicated, while in a larger room they can provide more targeted sound distribution.

Connections and control

For connecting to your TV, HDMI ARC or HDMI eARC is usually the most convenient option. Compatible devices can often be controlled using the TV remote. Optical and AUX are useful alternatives for older TVs or playback devices.

A Bluetooth soundbar is ideal for playing music from your smartphone or tablet. Depending on the model, a soundbar with app control may offer additional equaliser settings, sound profiles and firmware updates. Check that the app is compatible with your smartphone’s operating system and whether regular updates are planned.

Dimensions and positioning

Measure the space beneath your TV and the width of your TV stand. The soundbar must not block the TV’s infrared sensor. If you are mounting it on the wall, the bracket must be suitable for the type of wall. The subwoofer should stand securely and not be wedged directly into a corner, as this can affect bass reproduction.

Soundbar or projector: Which is right for your living room?

A soundbar complements your existing TV and is usually straightforward to use every day. A home cinema projector also requires a suitable projection surface, an appropriate viewing distance and controllable lighting conditions. With Full HD or smart projectors, you should also check whether streaming services are officially supported or whether an external streaming stick is required.

For families, secure positioning, protected cables and sufficient ventilation are important. With projectors, nobody should look directly into the active lens. At the end of their useful life, electronic devices should be disposed of separately in accordance with local regulations.

Soundbar for TV FAQ

Which soundbar is suitable for a small room?

A compact 2.1 soundbar with an integrated or wireless subwoofer takes up less space than a 5.1 or 7.1 system. Before buying, check its width, connection options and distance from the walls. In a small living room, a simple installation is often more practical than additional rear speakers.

Do I need HDMI eARC for Dolby Atmos?

Not necessarily for every type of Atmos playback, but HDMI eARC expands the range of possible audio formats and makes control easier. Whether you need this connection depends on your TV, soundbar and the streaming or gaming sources you use. If your TV only has Optical or HDMI ARC, compare the supported formats in the technical specifications.

How much does a soundbar cost to run?

Electricity costs depend on usage, volume, standby consumption and the subwoofer. Information about energy consumption can be found on the product label or in the instruction manual. If you use the soundbar every day, consider standby figures and whether automatic shut-off can be disabled, as well as the purchase price.
