Why is my HSU Subwoofer making a humming or buzzing noise?
- TTyler GomezJul 26, 2025
If your HSU Subwoofer produces a humming or buzzing noise, it could stem from several issues. First, disconnect all interconnects from the amplifier; if the hum persists, it indicates an amplifier problem, and you should contact technical support. The noise might also originate from your speaker wires or interconnects due to poor construction, oxidation, or damage. Try alternative cables and ensure they are positioned away from AC cables or power transformers. Another potential cause is a light dimmer or similar device on the same AC circuit; in this case, use an AC line filter or switch to a different circuit. If the hum disappears upon disconnecting interconnects, the problem lies with another piece of equipment. Reconnect each component one by one to identify the source of the hum.
