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?
Science and the science of how we hear are as yet imperfect...... 

like Baskin Robbins, a wide sample is best before deciding on that single cone....

better to get three....to paraphrase some desert wisdom:

Life is uncertain buy many speakers first

wolf - where are you mixing sound next ?????
I refuse to mention my gigs here to protect my privacy, as I can't be hassled by audio geeks when I work my magic. SECURITY!
Oswalds Mill Audio seems pretty cool, but no pricing. In any case, thanks for the reference.
I think the big speakers are 300 grand. I like the turntables. Wish they'd post prices.
