Anyone else have a slight humming/buzzing noise coming from the subwoofer when it is turned on? I've tried disconnecting all other cables besides the power and it still persists whenever I turn on the subwoofer. Also tried it in different outlets throughout my house. It's only slight, but I can notice it a bit when nothing is being played through the speakers.

Sounds like you may have a 60 cycle hum...they can be very tough to isolate. Is the speaker grounded? How long ago did you purchase the speakers?

I just received the speakers yesterday. The speakers are not grounded, but I've tried connecting it to numerous outlets throughout my house.

Here is a good explanation and sample of a 60 cycle hum. https://en.wikipedia.org/wiki/Mains_hum Is that what you're hearing?

It kind of sounds lower than the 60 hz hum, but higher than the 50 hz. I tried the subwoofers in two other houses and it's still the same. I already issued a replacement through Massdrop and they were fast to reply. I just have to wait a few weeks for it to be back in inventory.

I had the same problem with a subwoofer I purchased. It was made overseas where they use 50Hz. not 60Hz. I tried plugging it in at several different friends houses, but the hum was still there. I ended up having to return the subwoofer. I hated to have to return it because I loved the subwoofer. I just couldn't stand the constant hum.
