3 Ways to Cut Your Soundbar Energy Bill
- 🌱
Disable the 'HDMI-CEC auto power on' if the soundbar wakes up every time the TV turns on for a different source.
- 💡
Turn off the subwoofer's wireless standby if you're not using it — wireless receivers draw 3–6W continuously.
- ⚡
Reduce bass boost — deep bass at high volume requires significantly more amplifier power than midrange audio.
Startup Surge Information
Soundbars use low-power solid-state amplifiers with no motor, drawing very stable, consistent wattage.
