Hi DukeThats good news!
I had another look at the AES in library. Found an article in JAES 1979 ,May,by David Queen.
Not sure if this is the same article I mentioned to you 6months or so ago,because I thought the article talked of ~90° horizontal radiation angle in room beind ideal.(my imagination drawn from my own conclusions?)
This article talks about stereophonic reproduction in room,and the desire for minimised ceiling and floor reflections,and a smooth directivity,through theory and listening tests.Ofcourse toole refers to this recently - but cant see any obvious horn speakers in his tests.
He stops short of refering to horns/waveguides as being an answer,instead talking about omnidirectional speakers.
90° x 40 ° HF horn dispersion or similar seems useful,and correllates well with report on here. Note that THX requirements ask for reduced vertical reflections also.
2226 + H290 or similar cant be too bad,when one is used to 4" + 1" direct radiators :-)
