Buying a soundbar with a subwoofer: a guide for TV, films and gaming

A weak TV speaker, hard-to-follow dialogue or a lack of bass are common reasons for buying a soundbar with a subwoofer. But technical terms such as Dolby Atmos, 5.1 or 500 watts don’t tell you on their own whether a system will suit your living room. The key factors are the connections, room size, speaker layout and how you plan to use it.

Common mistakes when buying a soundbar with a subwoofer

1. Assuming more watts means better sound

A high power rating doesn’t automatically mean balanced sound. Depending on the manufacturer, the quoted figure may refer to continuous or peak power. You should also consider the number of channels, driver size, frequency range and room acoustics.

2. Expecting Dolby Atmos without a compatible source

A Dolby Atmos soundbar can process Atmos signals, but you’ll need compatible content and a suitable connection. HDMI eARC is a good choice for many TVs, as it can carry more data and multichannel audio. An older HDMI ARC connection or an optical cable may limit the audio formats available.

3. Mistaking a wireless subwoofer for a fully wireless system

A wireless subwoofer will usually still need a mains socket. ‘Wireless’ generally refers to the audio connection between the soundbar and subwoofer, not the power supply. Surround systems may also have additional rear speakers that need their own power or speaker cables.

Key things to check before you buy

Channel configuration and room size

The channel number describes the speaker configuration:

  • 2.1 soundbar: Two main channels plus a subwoofer; suitable for TV, music and smaller rooms.
  • 3.1 or 3.1.2: An extra centre channel helps make dialogue clearer. The ‘.2’ usually indicates two up-firing speakers.
  • 5.1 soundbar: Multiple channels, often with additional surround speakers, create a wider spread of sound.
  • 7.1 soundbar: A more extensive surround sound system, often with four rear or surround speakers. You’ll need enough space beside and behind your seating area.

In a bedroom or compact living room, a short 2.1 soundbar may be more practical than a large home cinema system. Films and games are more likely to benefit from separate surround speakers in a larger room.

Connections and audio formats

For a soundbar for your TV, HDMI ARC or HDMI eARC is usually the most convenient connection. It often lets you adjust the volume with your TV remote. Check for:

  • HDMI ARC or HDMI eARC on both your TV and soundbar
  • HDMI passthrough for external devices such as games consoles or Blu-ray players
  • An optical input as an alternative for older TVs
  • Bluetooth for playing music from your mobile phone
  • USB, AUX or Wi-Fi, depending on how you plan to use the soundbar

A Bluetooth soundbar is suitable for wireless music streaming. However, Bluetooth isn’t automatically a high-quality multichannel connection for films.

Placement, dimensions and controls

Before ordering, compare the soundbar’s width and height with your TV stand. Up-firing speakers need as much clear space above them as possible and a suitable ceiling height. Avoid placing the subwoofer in a closed cabinet, as this can affect its bass performance.

Useful features include automatic room correction, voice enhancement, night mode and app control. These can adjust the sound, but they’re no substitute for choosing the right position.

Soundbar with subwoofer FAQs

How do you connect a soundbar with a subwoofer to your TV?

If both devices support HDMI ARC or eARC, connect them using an HDMI cable plugged into the ports marked accordingly. Then enable ARC and, if required, HDMI-CEC in your TV’s menu. Optical cables or Bluetooth are alternatives. The audio formats supported depend on your TV, soundbar and source.

How long does a soundbar with a subwoofer last?

There’s no reliable way to give a fixed lifespan. It depends on factors such as how long it’s used, volume levels, heat build-up and the power supply. Keeping the ventilation openings clear, placing it in a dry location and using suitable cables can help it operate safely. Install firmware updates according to the manufacturer’s instructions.

Does a wireless subwoofer use a lot of electricity?

Power consumption depends on the model and whether it’s in use. It’s normally lower in standby than when playing, but the subwoofer still needs to be plugged into a mains socket. To save energy, use automatic shut-off or energy-saving features, and check the specifications for the model you’re considering.
