Yes, I think horns are becoming more popular. I have never heard a horn system that I could live with. That includes, the previously praised new and old versions, and yes with the supposedly correct amplifiers. I always hear that honky, nasal, shouty, sound. I always walk away from those systems shaking my head and muttering, "I just don't get it". Then again, many of the fans of those systems have publicly criticized the gear I prefer. To each his own, YMMV, etc..
Are horns and hi-eff designs becoming more popular
I feel they are but wonder what others think? Since today one can build hi-eff designs in most any type of loudspeaker. With many new hi-eff transducers availible. Hi-effs not just front or back horn designs anymore.
