Horn Speaker Recommendations

+1 for Volti. I was pretty impressed with those when I heard them, and I really enjoyed talking with the designer and builder (Greg Roberts) at Lone Star Audio Fest. He managed to make those speakers sound very good in a small hotel room, and they are clearly meant to shine in a larger space. I would reach out to them and you'll likely get to speak with Greg directly. If you're into high efficiency horns in that price range, I think just hearing his input directly would be worth your time, even if you go a different way. 

Wilson Benesch Torus retail for $12,900 with the amp/crossover. I am not a dealer the distributor is Aaudio Imports in Colorado. If that is too rich for you blood I would suggest a couple of small diameter subs, say 8" or 10" so they would be fast enough to keep pace with horns. 

"I understand the considerations in regards to interior decoration, but if you’re really into sound reproduction let your speakers be a main priority in the allotted space they’re given - with the adherence to form-follows-function as far as it goes, and not vice versa. As it often happens, to my eyes at least, the really interesting physical shape of speakers comes via an uninhibited accordance with their function as dictated by physics. Even a much smaller, typical slender square box speaker can be seen as an outright nuisance in a home setting because it’s just that: a tall, rectangular square box oftentimes finished in a rather sterile manner, and one that’s placed well into the room, at that."  Precisely right and  much of the speaker world, no let me restate this to 95% of the "high end" speaker world is form before function and then trying to make them to work well within the physical parameters of the pretty, avant-garde or techno-artisto box. OP wants pretty and decent sound which I can understand is the choice of most but when I close my eyes I want to pretend I am truly in one of the best seats in the live performance. I want spectacular sound and looks just don't matter.

Mahlman....trust me, I will not sacrifice sound for looks.  How I got on this horn search to begin with was hearing the Avantgarde Uno Fino.  That was the first horn I heard and in the same room I heard, Meridian, Eggleston, Vivid, Stenheim Alumine, Vandersteen.  My wife and I both loved the sound of the Avantgarde better than any of the other speakers.
I was shocked that my spouse would accept the look of the horn.  

I am going to listen to the Avantgarde Duo in October.  IMO they are overpriced but we will see.  I still like the hORNS Universum and the Symphonies.  I just had an opportunity to buy a used pair of Cessaro Liszt for an unbelievable price but at 980 pounds a piece, I just thought that would not work in my room.  

The biggest question I have now as I am about to embark on building my new house is, should I add to in wall subwoofers.  Even if I don't use them at least I have them ready.  With Horns being so fast, I would need a very good subwoofer.  My wife has laid the law down and said they have to be be in wall subs like I have in my current house.  

Also, beauty is a matter of opinion.  What might be a great looking speaker to me may be ugly to others.  So, if I can find great sound and good looking speaker, then I am a happy camper.  

"So, if I can find great sound and good looking speaker, then I am a happy camper. "  Absolutely and if you can do this you can't ask for more. If you find something that meets these standards in your eyes that is what matters.
  In my search for my audio standards to be met I could not find what I wanted and ended up building what has turned out to be in most eyes a visual klunker no doubt, but the sound is amazing and it is produced by the laws of physics in which best functional form can't be evaded. Properly done pure horns systems are unbeatable by any direct radiator systems and they do this by correct audio producing shape which can be done no other way. Side benefit to horns is also super efficiency and you don't need lots of power to run things.
  It is a shame this forum does not allow for pictures. It was mentioned to me that a build thread would be interesting and there were not enough of them here but I can see why. Can't post build in progress pictures nor finished results nor can you post actual measured audio results for people to see so it ends up being talk and no evidence. Can't post REW or TrueRTA graphs showing the benefit of doing things certain ways nor can anyone share screen captures of active digital settings that would work with Xilicas to balance and time align systems.
