We CK himself:
“The Kone is a modification of the K12H-200, where we have redesigned the inner wizzer cone down to a smaller size, to achieve a different dispersion pattern for the high frequencies.
The Kone / Kabinet and the adjaced digital part in the Profiler perfectly match. You cannot run another speaker (including the K12H-200) with it, as it would result in a reasonably different frequency responce.”
Oh cool... I hadn't seen that quote from CK. Thanks.
