Choosing a soundbar with a subwoofer: a buying guide to better TV and home cinema sound

A TV can deliver a sharp picture while the sound remains thin, quiet or hard to understand. A soundbar with a subwoofer adds a separate bass speaker to your TV and can bring greater clarity to dialogue, film soundtracks and gaming effects. However, high wattage figures and terms such as ‘3D sound’ don’t automatically mean you’ve found the right system.

Common pitfalls when buying a soundbar with a subwoofer

1. Wattage is mistaken for sound quality

Manufacturers often quote maximum output power. This figure alone doesn’t tell you about the sound tuning, dialogue clarity or quality at lower volumes. In a flat, it’s also important that the bass stays controlled and can be adjusted to suit the room.

2. Dolby Atmos doesn’t work the same way in every set-up

A Dolby Atmos soundbar can process compatible audio tracks. However, to hear height effects, you need suitable speaker configurations, an appropriate ceiling and a compatible source. Virtual surround processing works differently from adding rear speakers. So it’s best not to judge a system by its channel number alone.

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

A wireless subwoofer receives the audio signal without a cable connecting it to the soundbar, but it still needs a mains socket. Surround speakers may also need power or connection cables. Before you buy, check how the system will fit into your space and how long the supplied cables are.

What to check before you buy

Connections: HDMI ARC or HDMI eARC?

For a soundbar for your TV, HDMI ARC is usually the most convenient connection. You can often control the volume with your TV remote. HDMI eARC offers greater bandwidth and is designed for certain multi-channel formats and higher-quality audio transmission. Check whether your TV has an ARC or eARC port.

An optical input is a useful alternative, though it doesn’t support every modern audio format. Bluetooth or Wi-Fi are handy for playing music from your mobile phone. A soundbar with app control may offer extra equaliser settings, sound modes and firmware updates.

Channel configuration and speaker placement

The 2.1 designation usually means two main channels and a subwoofer. A 5.1 soundbar adds multiple surround channels, while a 7.1 soundbar may offer even more discrete or simulated channels. The key question is whether separate rear speakers are actually included.

With a soundbar that has up-firing speakers, Dolby Atmos effects can depend on the shape of the room. If you prefer clearly defined surround sound in your listening area, consider systems with physical rear speakers.

Size, power and placement

Measure the space beneath your TV and check whether the TV stand will obscure the soundbar. Wall mounting may be a good option if your furniture has limited depth. The subwoofer should stand securely and shouldn’t be completely enclosed by furniture or fabric.

Also check for:

  • enough ventilation around all devices,
  • secure cable routing to avoid trip hazards,
  • a mains socket where you plan to place the subwoofer,
  • compatible audio formats on your TV and streaming devices,
  • ease of use for night-time viewing, dialogue and gaming.

Set-up and day-to-day use

Where possible, connect the soundbar via HDMI ARC or eARC, then select the corresponding output option on your TV. If you’re using an optical cable, you may need to set the TV audio format to PCM. If the bass sounds boomy, avoid placing the subwoofer right in a corner. Small changes to its position can affect how the sound carries around the room.

At high volumes, make sure ventilation openings remain clear. Clean the devices with a soft, dry cloth and follow the manufacturer’s instructions. In Germany, electronics and batteries must not be put in household waste; use the designated take-back and collection schemes instead.

Soundbar with subwoofer FAQs

Is a soundbar with a subwoofer suitable for small rooms?

Yes, as long as its size, volume and placement suit the room. A wireless subwoofer still needs a nearby mains socket. In flats where sound travels easily between rooms, night mode, bass control and keeping the volume moderate are particularly important.

Do I definitely need HDMI eARC for Dolby Atmos?

Not necessarily. The way audio is transmitted depends on your TV, soundbar, source and audio format. However, HDMI eARC offers more bandwidth than ARC and is often the better connection for more demanding multi-channel formats.

How long does a soundbar with a subwoofer last?

There’s no reliable way to guarantee a set lifespan. It depends on factors including how long it’s used, volume levels, ventilation, power supply and software support. Keeping the system in a dry, well-ventilated spot and using suitable cables can help it perform reliably day to day.
