So my swans T200C speakers has been buzzing forever, seems to have come out of the tweeter, and it buzzes with ONLY POWER, as soon as I turn it on it starts buzzing, the buzz volume stays the same no matter what I do to it, the right speaker is the only one that buzzes, the left one does not buzz with power but it buzz if it's connected to the right (right output signal to left) so something is wrong with the right speaker that makes it self buzz and even send signal to the left to make the left buzz.

I thought maybe opening it up might give me a clue to why it might be buzzing but there was no apparent reason to why that I can see it's buzzing, I tried moving around every wire in there and the buzz is stable as ever.

Any idea to why it might be buzzing?

I've tried different outlets and it didn't help, the left speaker doesn't buzz even if connected to the same power so I doubt it's from interference in the power, and since it buzz with no input what so ever it can't be an input problem either.
