The horns, even the fast opening ones are physically too deep for their mouth’s size, and this leads to a psychoacoustic illusion that the sound images are arrested at the bottom of the horn and from there they scream they want to escape, but the listener does not hear them - he hears their echo jumping out of the horn. This is the most important reason not to use horns.
It is possible to throw fantastic imaging presentation by using direct radiator but did you pay attention that many playbacks do not do it? What does it mean? It means that an ability of playback to make imaging interning is ALSO derives from the skills and objectives of a system owner. So, if we have direct radiator people who are not able to get proper imaging out of their “superiors imaging topology” then why you deny that in horn world it would be possible to have individuals who are able to make imaging to work? I admit that with a direct radiators is it very easy to make imagine to be “sexy”, take any mini-monitors with ULF, put it anywhere and the will image fine. With horn it is much more complex and require MUCH more space. It is perfectly doable however. Putting put horns stuck at least 6 feet from the back would be a good direction to start.

Very unsatisfactory level of tonal discrimination. There are two reasons having negative impact on tone. The first reason is the horn itself. The sound of the compression driver accepts the inherent sound characteristics of the horn’s material. These specific sound characteristics affect any single note that passes through the horn in exactly the same way, effectively homogenizing the variety of original colors that are contained in the recordings. It is the same as wearing sunglasses. You can see part of the original colors of the objects around you, but you always see the added “color” of the glasses. The second reason is the compression driver. For tonally rich midrange and upper midrange, the diaphragm must be at least 5-6”. But if it is so big – then the sound of the upper range goes into the toilet, that’s why nobody uses big sized domes. I will not mention the big voice coils as a reason for bad tonal discrimination, because there is a way to construct compression driver with relatively small, tone capable voice coils (sacrificing few dB of efficiency). So it is downside of the specific implementation, not the topology. The same is valid for the material of its diaphragm.
Well, do you see anybody force you to “accept horn topology”. What you say is what you say and all that I advise you is to not make very advanced claims about utilization of oval horns if you do not have practical experience with horns basics. Yes, most of compression drivers with horn are not good for tonal discrimination, but the same with direct radiators. Do I need to add that most of the direct radiators are horrible for dynamic discrimination? BTW, pay attention that I do not claim that direct radiators are unusable because of high level of dynamic compression.
