Thanks for your response, but I'm aware that he's using Spinorama. My question isn't HOW he produces the pretty pictures, it's how he decides what is important.
Forgive me if I'm incorrect in assuming your response is out of ignorance, but all of the speakers you listed are boxes. I'd say traditional, but Klipsch (horns, founded 1946), Magnepan (planars, original design 1969), and MartinLogan (electrostats, founded 1979) are all US companies with very high profiles in the audiophile community for 46-79 years, long enough to considered traditional in their own right.
There are also newer designs, many using the sort of drivers you would recognize, that are configured to produce dipolar or bipolar radiation patterns. There are even omnidirectional speakers on the market now. All of these designs have advantages & disadvantages, proponents & detractors, and will measure very different "on paper". It may well be that Amir avoids all of these issues by sticking to domes & cones in a box, though.
I did find a thread on ASR entitled "Dipole vs Box speakers" - 5 pages long, nothing from Amir, some skeptics, some converts. I'm not suggesting any one design concept is superior, but if this is all new to you, you might want to explore listening "out of the box". It could change your life (or at least, sound system)!
