I'd be curious to see how they modeled that. It looks like a very small horn with a large phase plug, but if you look at the cutaways you can see it's really a sort of tweeter horn sitting inside another horn (which won't have much effect). It's probably never going to sound good, but they might manage something listenable if they modeled it as a regular exponential horn. Are you guys around here? How did you come up with that shape?
