This can result in a low-frequency hum or buzz coming from the subwoofer.

It's also possible that there is a problem with the subwoofer's internal components, such as a faulty amplifier or power supply, leading to the humming sound. **

Regular maintenance and ensuring proper installation can help reduce the humming noise from the converter. **
