The Kone is for sure FRFR and it is supposed to be, as we advertise.
Please take care to have the "Kemper Kone" mode activated at any time.
And position yourself off-axis to the speaker, as you would do with a guitar speaker.
Kone is activated and I'm standing 45° off-axis as I would do with an amp. I've thought it was solved, but yesterday evening it was again fizzing on the highs. I've also tried connecting other active monitors and they don't do it. Maybe is something wrong with this one? I had once a Monitor that blew the tweeter, and was sounding similar.
BTW, thanks for chiming in
