Hi Tony,
I seem to remember that when I had my KN6000, I experienced a kind of 'Buzz', when certain notes were played. I eventually traced it to a resonance in the cabinet rather than a faulty speaker. In the process of dismantling the KN6000, I discovered that it was due to a loose cabinet fixing screw! Having tightened the screw, the 'Buzz' Buzzed Off
