Exactly my thoughts.
I spent some fruitless hours trying to set up a second system this afternoon.
But I did some simple tests. I wouls have no music playing. I turned the light on. I could hear light clicks from the right speaker synchronized w the flickering of the florescent light coming on. Then the loud pop turning off. Same thing three times in a row.
I don't believe it was effecting the left channel. It is further away.
I'm thinking airborne RFI. The powered speaker has something to do with the magnitude of the pop IMO.
