I believe I have to read the mentioned thread from GT to understand this...
As seen in your posted graph, a linear frequency response under angle seems to be a major factor, right?
@ivica:
The fins seem to affect the high-frequencies more than the mid-frequencies and this results in a different dispersion over frequency. Did I get you right?
@Ian:
The yuichi-horn without the fins seems to have a rising freq-response on axis. The yuichi-horn with fins is rather flat on axis. But what does is tell about the imaging ability?
