Hi guys, about two months ago I purchased second or third hand speakers via AVForums classifieds, and now the sub has gone faulty.
I think that the driver is gone as it hums in low frequency constantly as soon as power goes to it and there is smoke too!
Below you will find a recording of that phenomenon, so please advice if it is the driver or the circuitry problem as one of the two big capacitors is slightly bloated, but only slightly.
Video of the problem, see the smoke at the end when I kill the power:
YouTube - KEF Coda S - burnt, smoking driver?
Images showing bloated capacitor, the one on the right:

Image 2 (~ 1MB)
What do I do, buy just new driver, replace capacitor or buy a new sub from BK, using the group purchase in the other thread?
