Pooge,I'm more hung up on Clarity ( Sonic and Semantic ) than on CD horns.
People often respond to what they think was written ( what they want to hear ) rather than to what actually was written; when I take time to discuss an issue, I want to be understood.
I do hear what you are saying, and I do concede Dr. Geddes ideas may be 100% correct.
Anything is possible. I hope he is correct.
HOW probable is that though ?
Life is too short to investigate every "new" idea that rolls down the pike. In general, in any 'area of interest'/hobby you have to discriminate, filter out 95% of what's 'available', because there are just so many options ( which are relatively inferior to the best ones available ).
There are many ways to skin a cat ( or design horns ) but there is only one way that's Best for Most People, Most of the Time.
I realize there are ways other than CD horns to control directivity.
Multiple-cells, Multiple horns, Sectoral horns.
Heck, even my rectangular Edgarhorns have wider HF projection when they are oriented horizontally, than vertically.
Most ' directive ' horns though seem to have some sort of geometry that radically " alters " the way sound waves are normally projected/transmitted ( mainly through a process of diffraction/refraction ).
HF sound waves are naturally directional. HF sounds don't " radiate " widely in nature ( that's why we can't source-locate LF sounds very well ). And, based on my experience, midrange sonic 'lenses', CD horns, wave guides, etc., etc., don't sound as good as straight Tractrix horns.
Which makes me think mechanical manipulation to " spread " HF's, for better off-axis frequency response usually ( maybe almost always ? ) degrades the sound on-axis ( Hell's bells, even ' acoustically transparent ' grill cloth screws up the sound ).
I have not heard every horn/waveguide/lens out there obviously, so loading/directivity-devices may exist that don't sound bad or 'not as good', but, as I said, my experience, and what little I know about Acoustics, make me skeptical.
If Dr. Geddes has made a ' breakthrough ', that's great, more power to him.
There are a few other issues btw, that Dr. Geddes raised that raise doubts in my mind about his theories, especially the idea that you need room reverb to make a recording sound 'spacious'.
In my opinion, you should eliminate listening room ' sound/acoustics ' as much as possible by minimizing reverb/echo. The idea that rear wall reflections create an ambient ' soundfield ' is counter to my understanding of how stereo should be done.
In my opinion a speaker system should sound as good outdoors or in an anechoic chamber ( if not better ) than it does in a room.
I realize it's almost impossible to do that with single-amping a conventionally filtered system. But that's just another reason to use high-Z filtering and multiple amps. That way you can attenuate bass levels to de-compensate for different spaces varying room boosts.
