Well, I have a pair of shahinian obelisks, which I believe qualifies as a radial speaker and I love them. More realistic and less hi fi than many more traditional speakers. I have not heard Ohm speakers in a zillion years, but liked them back in the day.
There are just not too many examples out in stores. Maggies are not quite the same, but the backwave does extend the realism of the music, compared to live, especially for acoustically generated music.
