    Re: What's wrong with this Picture?

    My thoughts were on the odd mid/tweet arrangement and how might this sound 'like a very very good coaxial' ?.....which to my experiences to date doesn't yet exist.

      Mid to tweeter x-over at 4.5KHz? That's about a 3 inch wavelength. Seems like it would have major "path length interference" issues as you moved to the sides. Every location that had a path length difference of 1.5 inches (relative to each of the four mids) would have destructive interference.

      I guess I would need more info on why this geometry was chosen. Perhaps there was a reason... but with so many peaks and nulls due to the physical geometry of the four mids, I'm a little worried about this one.

      The polar response would probably be extremely erratic instead of smooth and predictable. Certainly not even remotely close to the original recorded event.

      Hmmm... has anyone run this geometry through CALSOD or a similar program?
