Mackie Big Knob Passive vs Kali LP6 - distortion etc.

Heya everyone, I just registered because I'm pretty lost in my case here.
I have rebuilt/upgraded my studio and wanted to add a monitor controller. Went for the Mackie Big Knob Passive.

And this just worked fine. At least with my 10 year old ESI NEar 05 Monitors, just as expected. I mean, it's a passive controller, what could go wrong.

Now I decided to upgrade and bought a pair of LP6s by Kali. Plugged them in, set the input gain to unity (just like with my ESIs) and then experienced pretty low volume on the speakers and pretty heavy distortion. And now here's where I am starting to ask questions. I tried to figure out what caused the problem and I went through all these scenarios:

IO (Behringer UMC 1820) -> Big Knob -> LP6: Distortion
IO -> Big Knob -> ESI NEar 05: perfectly fine.
IO -> LP6 directly: perfectly fine.
IO -> Big Knob -> IO (for testing in Cubase): perfectly fine.
3.5mm Jack Aux -> Big Knob -> LP6: Distortion

I tried different cables, symetrical, non-symetrical, tried trs->xlr and went through all the ins and outs on the Big knob, all with the above results.

My conclusion is that all the devices are working fine, but something seems to cause an issue here. And I have no clue what that would be. If anyone can help me, pleeeease do so!

Many thanks and much love!

Edit: Figured I might have submitted to the wrong sub forum, If any of the mods would move it, greatly appreciated!

That's really strange. Did you find the problem? Did you really use the same cables, plugs, etc?

When did you buy those Kali’s?

If I’m not misstaken they were all pulled from the market by Kali a few months ago for distortion...

First I've heard of this; was it a specific batch/serial numbers or all?

I think it was the first batch of every speaker sold, atleast in the EU.
