A soundbar can make television dialogue easier to hear without the space and wiring of a full speaker system. First check the width of the area beneath your screen and whether the bar will block the television's sensor or bottom edge. Decide whether you want a simple all-in-one bar or a system with a separate subwoofer or rear speakers for a broader presentation.
Connection options are important. HDMI ARC or eARC can let a television send audio to the bar and often allows one remote to control basic functions. Optical audio is a useful alternative, though it may not carry every advanced audio format. Check that the soundbar supports the sources you use, and consider Bluetooth or network streaming if you want to play music from other devices.
Listen for clear speech at ordinary volume, not just dramatic bass or loud effects. A dialogue mode can help with quiet voices, while a night mode may reduce abrupt changes in volume. Placement also affects sound: leave the speaker grille unobstructed and follow the manufacturer's guidance for a subwoofer. After connecting everything, confirm the television is outputting audio to the correct device and test dialogue, music, and action scenes.
Beyond the Basics: Formats, Calibration and Everyday Use
Once the essentials are covered, a few less obvious details separate a soundbar you tolerate from one you enjoy using every day. The first is audio format support. Many streaming services and discs offer Dolby Digital as a baseline, while some titles carry Dolby Atmos or DTS:X, which add height information. A bar with upward-firing drivers can bounce sound off the ceiling to suggest overhead effects, but the result depends heavily on ceiling height and material. Flat, reasonably low ceilings work best, while vaulted or sound-absorbing ceilings reduce the effect. If your room is not suited to this, a well-tuned bar without height channels may serve you better and cost less.
It is also worth checking how the television passes audio through. Some TVs can only forward compressed formats over ARC, which is why eARC matters if you plan to use lossless or object-based audio from a streaming box or console. If your sources plug into the TV rather than the bar, confirm the TV's audio output setting allows passthrough rather than converting everything to basic stereo.
Room calibration and adjustment
Several soundbars include automatic room correction, using a built-in or phone microphone to measure how sound behaves in your space. This can tame boomy bass in a small room or brighten a heavily furnished one. Even without it, look for manual controls for bass, treble, centre channel level and subwoofer level. Being able to raise the centre channel slightly is often the single most effective way to improve dialogue clarity.
Practical points that are easy to overlook
- Display and indicators: a small front display or clear status lights help you see which input and mode are active.
- Wall mounting: check whether a bracket is included and whether the bar's drivers are designed to work when mounted.
- Software updates: network-connected bars may receive firmware improvements, so models with an active app tend to age better.
- Lip-sync adjustment: an audio delay setting fixes mismatches between picture and sound, especially with gaming or picture-processing modes.
Finally, think about the screen the bar will sit beneath. A larger television generally pairs better with a wider bar, and if you are still choosing a set, our guide to choosing a 4K TV covers the audio connections to look for. For streaming-capable bars, a stable home network matters too, which our article on choosing a Wi-Fi router explains.
