A horn is just a waveguide and has nothing to do with the type of tweeter it's attached to. IME they do tend to have a more immediate feel to them but horns ultimately have nothing to do with 'unforgiving' sound reproduction.
I'm not in any way some sort of an informed audiophile so I'm probably describing things entirely wrong, but at this particular moment it feels like the horns are shooting high frequencies into my eardrums as if they are some sort of weapon when I'm rocking out and then the wrong song on youtube comes along.
I listen at high volumes, not what you would find in a club but more than most audiophiles would.
I am talking about a song that is fine with less revealing speakers, but instantly they are not fine with these and just painfully harsh.
One moment I'm in absolute bliss at the high volume I love when everything is right, and then oh no this is not comfortable I have to rush the drop the volume because all of the sudden it is not pleasant at all any more.
It really has improved with the douk a5, so I'm leaning towards the idea I just need equipment on the level of my expectations with this good of a speaker and trying to use a sub $100 amp and be satisfied with it is just silly.
