Not to dispute your points on directivity Wayne, but I find it strange that the exact opposite approach has been marketed as the most "natural" approach, with omni-directional speakers. Their argument is that when sound is produced naturally, it radiates out spherically in all directions. Therefore, speakers should be designed to do the same thing. I think this argument is valid in some respect but flawed in others. Not all instruments radiates sound omni-directionally. Brass and woodwinds are examples. Even natural speech is directional to some extent.One thing I don't understand is how can omni-directional speakers be marketed at producing better soundstage and larger sweetspot when a large part of what you hear from them is reflected sound?
