A soundbar is often the easiest way to upgrade a TV’s audio, but many users may unknowingly be damaging their device.

Experts say everyday habits — from poor placement to ignoring software updates — can lead to distorted sound and long-term performance issues.

Even when a soundbar seems to be working fine, certain overlooked practices can quietly reduce its effectiveness.

Sticking with factory settings, placing the device incorrectly, or skipping firmware updates may not show immediate effects, but they can strain speakers, reduce clarity, and limit the soundbar’s full potential.

Incorrect placement

Placing a soundbar in the wrong location can significantly affect audio quality.

Experts recommend positioning it below the TV on a flat, stable surface to prevent sound from bouncing off furniture or other obstructions. Poor placement can result in muffled dialogue and uneven sound distribution.

Soundbars need proper airflow to function safely.

Blocking ventilation vents can cause overheating, which may reduce performance or damage internal components over time. Users are advised to keep vents clear, regularly clean dust with a microfiber cloth, or use compressed air when needed.

Placing a soundbar in direct sunlight can also lead to overheating, even when the device is turned off.

Ideally, soundbars should be kept in a cool, dry area. If space is limited, covering the device between uses may help reduce heat exposure.

Not fine-tuning audio settings

Most soundbars come with factory presets that offer average sound quality but are not optimized for individual rooms.

Room size, furniture layout, and seating position all affect how audio travels. Without adjustments, users may unintentionally push volume or bass levels too high, which can strain speakers over time.

To get better results, users should fine-tune sound modes, equalizer settings, and adaptive features through the soundbar’s companion app or TV settings.

Adjustments should be made from the usual seating position to ensure voices remain clear, bass stays controlled, and volume levels are balanced.

Skipping firmware updates

Firmware updates are often overlooked but play a critical role in soundbar performance.

These updates can fix bugs, improve sound quality, and introduce new features. Missing updates may prevent the soundbar from working at its best or cause compatibility issues.

Firmware updates are typically available through a soundbar’s companion app or the manufacturer’s website.

Users are advised to enable auto-updates when possible. For models without apps, updates may need to be installed manually using a USB drive, following the manufacturer’s instructions.
