There is also some research on our "perception" of frequencies out to 100kHz or so, that is not in the spectrum of normal "hearing". I wonder if this explains some of what people like in those Raal ribbons and others that extend way way up.
I think it has to do with the near perfect dispersion of the RAAL's above 15khz regardless of the axis. I have the 140-15D Dipoles and they changed the way I thing about 10khz+.
