Soundbar with subwoofer: how to find the right sound for your TV and home cinema

TV audio often sounds thin, dialogue gets lost in action scenes and there’s no suitable speaker for powerful bass. A soundbar with subwoofer can improve the sound without the need for a separate AV receiver and several large speakers. However, high wattage figures, channel counts and terms such as ‘3D sound’ don’t automatically mean it’s the right choice for you.

Common pitfalls when buying a soundbar with subwoofer

1. Confusing wattage with sound quality

Depending on the manufacturer, the stated power output may be measured under different conditions. That’s why peak power is only a limited guide to volume or sound quality. Other important factors include the speaker layout, room size, signal processing and sound adjustment options.

2. Expecting Dolby Atmos without the right setup

A Dolby Atmos soundbar can reproduce compatible audio tracks with a sense of space. However, to transmit larger amounts of uncompressed audio data, an HDMI eARC soundbar paired with a TV and source device that support eARC is usually a good choice. Features may be limited when using HDMI ARC, an optical connection or incompatible audio formats.

Upward-firing speakers can also use reflections from the ceiling. The result therefore depends on the ceiling height and material, your seating position and the layout of the room. Dolby Atmos is no substitute for suitable room acoustics.

3. Misunderstanding what ‘wireless’ means

A wireless subwoofer will generally still need to be plugged into a mains socket. ‘Wireless’ usually refers to the audio connection between the soundbar and subwoofer. Rear speakers in surround systems may also need power sockets or speaker cables. Before buying, check which components really work without audio cables.

Check these features before you buy

Channel layout: 2.1, 5.1 or 7.1

The first number describes the main channels, while the second refers to the subwoofer. A 2.1 soundbar typically consists of two main channels and a subwoofer. A 5.1 soundbar adds a centre channel and surround channels. A 7.1 soundbar may include several surround speakers or virtual channels.

Important: the channel count alone doesn’t tell you whether there are separate speakers in the room. Check the product description for terms such as ‘Rear Speaker’, ‘Surround Speaker’, ‘wired’ or ‘wireless’.

Connections and audio formats

These connections are useful when linking your soundbar to your TV:

  • HDMI eARC: suitable for high audio bandwidths and compatible multi-channel formats.
  • HDMI ARC: sufficient for many TV uses, but offers less bandwidth.
  • Optical input: useful with older TVs, but with limitations for modern audio formats.
  • Bluetooth: handy for playing music from your smartphone, but not always the preferred connection for TV audio.
  • HDMI input and passthrough: useful if you want to connect a games console or Blu-ray player directly to the soundbar.

A Bluetooth soundbar is therefore a flexible choice for music, but it doesn’t automatically replace a suitable HDMI connection for home cinema audio.

Size, positioning and controls

Measure the width of your TV stand and check that the soundbar won’t block the TV’s infrared sensor. For models with upward-firing speakers, make sure a shelf won’t obstruct the top of the soundbar. Place the subwoofer on a stable surface and avoid putting it directly in a tight corner, as this can make the bass louder or uneven around the room.

For everyday use, other practical features include automatic room calibration, dialogue enhancement, night mode, app control and a shared remote control.

Setting up a soundbar for your TV

  1. Where possible, connect the soundbar to your TV using HDMI ARC or eARC.
  2. Enable HDMI-CEC in the TV menu and select the appropriate multi-channel or bitstream format for audio output.
  3. Don’t put the subwoofer in a closed cabinet, and make sure it has a stable power supply.
  4. Position rear speakers to the sides of, or slightly behind, your seating position.
  5. Try dialogue, film, music and night modes at realistic listening volumes.

With a soundbar with wireless subwoofer, the subwoofer should pair automatically when switched on. If it doesn’t, check the manufacturer’s pairing instructions and try moving it closer to the soundbar.

Frequently asked questions about soundbars with subwoofers

Is a soundbar with subwoofer suitable for music?

Yes, as long as it has Bluetooth, Wi-Fi or a suitable streaming connection. For listening to music, the equaliser, music mode and subwoofer position may matter more than a high channel count.

How long does a soundbar last?

Its lifespan depends on how long it’s used, ventilation, dust, volume levels and software support. Keep the components in a dry place, don’t block any ventilation openings and use the supplied power adapters. Install firmware updates in line with the manufacturer’s instructions.

Does a wireless subwoofer use a lot of electricity?

The soundbar and subwoofer each use power while operating; consumption is usually much lower in standby. The exact figures vary by model. To reduce power consumption, use automatic standby features and switch the system off completely if you’ll be away for an extended period.
