Being German, I strongly suspect that "DKK32" stands for "Dynamische Kopfhörer-Kapsel, 32mm" (dynamic headphone capsule with a diameter of 32mm).
Part 22 in the K240 service documentation is the baffle and DKK32 + 22a seems to imply that the DF capsule always comes with a special baffle when you order it.
This is strange of course, considering that DFs seem to have been made with both kinds of "Monitor" baffles.
The way things are, we can only speculate whether the Monitor and DF capsules are any different at all, they certainly seem to look identical (and for the record, so do the K270 and K280 capsules, except that they're 150 Ohms a piece and the K270 is supposed to have two different capsules and a different "bass resonator" for each kind of capsule per side).
My *guess* would be that this whole "22a" business may be an attempt by AKG to obscure the fact that the difference between both models is a drop of glue. Maybe not every customer would have appreciated the "elegant simplicity" of this solution (along with the price difference) and maybe they also wanted to make "reverse engineering" harder.
As I mentioned earlier, they didn't exactly make the "bass hole" business a secret with the K280 but then, there aren't different K280 models - it was just used to tune the two capsules on each side.
I really would like to talk to the guy(s) who designed this stuff![]()
