Horn based loudspeakers why the controversy?

most of the worst speakers ive heard was horns.

when horns sounds coloured, nothing else in the audio world is so unbearable to my ears

Absolutely true murphythecat. Horns can be the most annoying loudspeakers to listen to but, don't hold that against all of them. There are some excellent sounding horn systems out there and because they are strongly directional can be easier to set up then regular dynamic speakers. Room acoustics are not as critical and you can get a pretty decent image out of the box. Their efficiency allows you to get away with a much smaller amp and save money. However, horns are big nd they will own any room you put them in not just because of their size but their appearance also. You could make an argument that my ESLs blend in but, there is no blending in with naked horns.

I don't know why one would necessarily want big speakers to blend in visually - kind of goes contrary to their nature. If you got the dedicated space to house something like big horns, let them unapologetically take up the environment they inhabit and functionality have its say. I for one like the purity, honesty and looks-by-way-of-function not watered down or over aestheticized. I lets you know their true purpose. 

Well stated phusis. I agree completely.
