Replaced the capacitors tongiht, works perfectly! stpete cooling you nailed it. TopMarc and DonnieZ if it wasn't for you guys I wouldn't have even tried to replace them. Thank you all.
To anyone else out there with the same problem. If you're thinking about replacing them on your own, take note of the above comments. It's a REALLY tight space to work with, the only saving grace is that there's alot of room on the board it's not crammed tight like a computer part would be. There was no visual damage to the Capacitors so going in I didn't know for sure that was the issue but turns out the humming is gone.
Love these speakers and was dreading the repair bill until I wonder upon this thread.
