As I have mentioned previously I’m slowly in a process of assessing other opportunities for my Macondo, since the EV T350 driver it too soft to be paired with Vitavox S2. While I am doing it an old observation keep knocking in my head. A few years ago I was experimenting with some tweeters over 10kHz and I detected that using them in indirect application was kind of “interesting”. At that time I did not use S2 but I took a note of the effect. I was making dipole with T350 drivers and ribbons, used Heil’s drivers and some custom made tweeters (inverted compression drivers) and I detected that when I positioned them back to back and turned them 90 degree off the MF horn direct line then HF turned out to be “fascinating”. I would not go into deeper explanations as I did not make those experiments with sufficient amount of precession and accuracy but now I would like to try something in this direction again.

Are anyone know any Harry Olson- level writing describing the mechanism of tweeters line arrays, parabolic arrays, hemispheric arrays or Null-set dipole tweeters? The Pro-audio folks uses them for years but I wonder of any theoretical research ever was dome into this direction.
