Horn based loudspeakers why the controversy?

As just another way to build a loudspeaker system why such disputes in forums when horns are mentioned?    They can solve many issues that plague standard designs but with all things have there own.  So why such hate?  As a loudspeaker designer I work with and can appreciate all transducer and loudspeaker types and I understand that we all have different needs budgets experiences tastes biases.  But if you dare suggest horns so many have a problem with that suggestion..why?

I believe any and all Altec compression drivers had phase plugs. They changed some of their characteristics  (Tangerine) to extend and smooth out high frequencies.

Did the classic Altec A7 811 horns from 1970 have phase plugs? I thought the "Tangerine" thing was later but I'm now not sure..

Compression drivers of all types, from what I remember, had a phase plug. The Tangerine came later, (mid 70's) first used in the Altec Model 19. The phase plug was needed to make the compression driver work properly. I don't know the mechanical or electrical reasons why. I think Altec came out with the Tangerine because one of the chief complaints about these drivers was a lack of HF extension. I remember my home pair of A-7's having more of a "whoooshhh" sound  on cymbals rather than the nice extended "crash" sound a cymbal has when struck with a stick or mallet. This was much improved with the Model 19. IMHO

My Airpulse Model one speakers have a horn loaded ribbon tweeter which I find to be very extended and detailed. Not a true horn but an interesting implementation nonetheless which sounds verg good to these ears
