So the issue is that the "pop on turn-on" is much worse with powered speakers than passive speakers? That's exactly what you'd expect if the powered speakers have a higher input impedance. The series capacitor in the K3 output along with the load impedance forms a high-pass filter. The higher the impedance, the lower the cut-off frequency and the louder the pop.
Has anyone tried connecting a 10 ohm (or so) resistor from the powered speaker's input to ground? I bet that would reduce the pop considerably.
