Hi

I just bought a pair of M22 onwall, VP150 onwall and a pair of QS8 for sides a couple of weeks ago. One of my M22 has been crackling occassionally. I hear the crackle whether I set them as "small" or "large". I have checked all my wiring & connections. I also switched my right & left speaker to see if it was the connections, but the same speaker continues to crackle.

Any help would be appreciated.
