I bought Edifier s330d for my new comp.
They work great, but over the time of 1 month of my ownership of them the sub is starting to show some buzzing sound.
At first week or two there was nothing, but one day the sub started buzzing on and off for a minute or two and then stopped and worked normally.
Every day that time expands and the sub is making that sound longer and longer, today I'm 20min into speakers on and it's still doing it. Today it was buzzing constantly for like 10min and afterwards it's doing on and off buz for lets say 20sec on and then 10sec off.
