Bada bing! You no lika de speakers?
Grammar: The difference between feeling your nuts, and feeling you're nuts.
Outdated and sub-optimal horn flares, too many sharp edges leading to unwanted diffraction (read: distortion) and the high-mid trumpet thing is just plain stupid.
What's not to like?
Sharp edges. Of course, how stupid of me! Next time I audition speakers I will take a protractor.
Sharp edges can certainly pose a problem due to diffraction. For the most part they are undesirable in a speaker cabinet. I would like to hear the designer's explanation of why they didn't seem to be concerned with multiple right angle edges on their cabinets.

In a direct radiator speaker the souce is mounted on a baffle and the baffle edges are of a large acoustic size compared to the wavelength of the sound especially in relation to higher frequencies.Diffraction is a problem.
The LV Olympians are multi way horns and there is no baffle. The sound wave has expanded along the length of the horn and when it reaches the edge of the horn the acoustic size of the horm mouth edge is small compared to the sound wave so diffraction is not significant.
Dr Earl Geddes begs to differ with you on that one and frankly I trust him a lot more than you.
... Earl Geddes is very trustworthy indeed on waveguides and directivity. This is about horns and diffraction though.
All horns are waveguides but not all waveguides are horns.
Diffraction is bad in any of them.
It was hearing the then fabulous Voigt Domestic Corner Horn as a youngster that got me into hi-fi so many years ago. However I find all Horn speakers I have auditioned including Voigts are colored and whilst they can give a very impressive sound they are IMO not accurate, or completely realistic, I could not live with any Horn speaker. So do not waste a $1m.

..I admire your concision.
Except I doubt Geddes has ever built a speaker that sounds that good! So, while it might be a minor issue I think there are other, more important things that were nailed with the LV speaker and are probably lacking in nearly everyone else's speakers.
BTW, I have heard the same Kondo gear at Black Forest Audio in Germany, M-77 preamp, Kondo KSL DAC and Gaku Oh monos on different speakers and it was quite impressive as well but still nowhere near the realism that it had with the LV speakers.
So you are saying that the diffraction artefacts are clearly audible in a 'lesser' speaker but not in an allegedly better one?
That makes no sense whatsoever because if anything they would be more obvious.
I don't know how you got that out of what I said because that is NOT what I am saying. I am saying that I think you are overplaying the importance of diffraction artifacts with a horn design where the dispersion is clearly controlled how they want it to be. Normal diffraction issues like imaging problems were simply not evident with that system that had AWESOME imaging. Say what you think is right or wrong in theory but it is only that...theory and not the practical reality.
Diffraction = distortion. That is all there is to it.
Theoretically I can't disagree, but it doesn't seem to be an audible problem with these loudspeakers.
