For clarity sake I think its important to note that I don't disagree with what Duke is stating other than how he is applying these theories to the subject as all encompassing explanations which is the only area I disagree. The deviation from ideal is where my point is defined, In the vacuum of the theorethical conditions Duke is correct as we know psychacoustics today.
The comment about the scale of image for example, the comment about "not being setup right" means that no fullrange Dipole system I have ever heard has been setup correctly. Because A dipole's cancellation isolates the rear wave into a distinct channel and this channel is always going to behave ideally which Duke's argeument hinges on. And its affect although pleasing still represents signal distortion as do reflections from other areas as you will find in all speakers. The inherent decoding problem of only using two speakers is another factor in this discussion and it is too complex to explain in short points. I have no motivation to write the 5000 words minimum to explain my position, only to have it picked apart for the sake of saying one's opinion about the clarity of a speaker.
