Guess I was not 100% correct in what I said, I found a very good description from CK in one of the Kone threads:
Quote CK:
As you know, the Kone will support two directions.
I have optimized the linear route in our Kabinet, which is a fully closed cabinet [no ports). I have used some of the best studio monitors and other speakers as a reference.
I am confident you will achieve excellent results in other closed cabinets as well, since the air volume of regular cabinets does not differ too much. This is also true for 2x12 and 4x12 cabinets, as you would divide the effective volume by 2 or 4. If a problem arises still, even software updates would be an option.
But when you run the linear sound in an open back enclosure, you will loose the low and, and thus not being that linear. But that is not a bad thing, as you would anticipate this loss, when you play an open back.
My approach for the imprints was different. There it was not about a linear device, but a speaker that should produce the same sound as a reference speaker, no matter what cabinet it is.
So I had the original guitar speakers mounted in our Kabinet and compared it to a Kone in another Kabinet side by side. By this approach the imprints are independent of the cabinet, as the influence of the cabinet is equally applied on both reference and Kone, and thus falls out of the equation.
We did some quick tests with an open cabinet a while ago and we liked it!
Because the Kone‘s dispersion pattern is wider (less beam), the sound radiated backwards looses a bit of relevance, but this is not a negative aspect at all.

Guess it will never sound exactly the same, but it sounds great
