No idea. I’m only dropping in because, although I’ve heard horn designs here and there over the years, I wish I had more experience with them. (My room set up has never favored horns, though).
Just for clarity: what exactly do you consider to constitute a horn design? Is it any speaker that uses some form of wave guide?
I felt the jbl Everest speakers were the best (or at least my favourite) at the last audio show I attended. Beautiful timbral reproduction of an orchestra, great dynamics, and I don’t seem to remember thinking the imaging sucked. But then again I’m not sure how much I was paying attention to that.
