Horn based loudspeakers why the controversy?

@kosst

Sadly, you would have to visit Buckingham Palace (well not the actual palace, but quite close,lol)  to listen to the H1's.
Or in the vicinity of Norad to listen to a pair of Oris horns.
Both to my ears are very good. 
Enjoy your music!

I listened to horn speakers for the first time recently, Trenner & Friedl RAs powered by Shindo. It's either my first or second favorite setup I've ever heard, and I've heard all the big brands. 

Over seven decades, I've owned both horn and direct radiating speakers.  The way each presents its sound is akin to what I experienced in Vienna several years ago. I was fortunate to hear the VPO play in both the Staatsoper and the Musikverein.  Same orchestra - - but playing in two clearly differing sonic venues.  
IMO, the playing in the Staatsoper was akin to direct radiation/cone speakers, while the playing in the Musikverein was more "in your face" like I had experienced with my horns. 
I enjoyed them both, although  each presented the music as different audible (and emotional) experiences. I guess it's a choice as to which approach you prefer as a constant diet over the weeks, months and years. 

I have a pair of Bob Crites Cornscala’s with DeanG crossovers and they are amazing. They do a lot of things really well with exceptional detail and midrange. Very revealing speakers. YMMV
