If you were top view the enclosure as a cylinder, then cut the v vents at one end, you have the patent for part of the Karlson.
It is in an AES paper I can't quite recall now. Using this technique, you flatten the impedance curve to nothing. This is how I got the idea to suppress the resonances in my RMAF box. It would work better if a cylinder.
Perhaps Freddi has the link to the paper.
I tried this on a straight horn, and it did work, at the expense of losing low end.
