Horn Speaker Recommendations

I would have to agree with Avantgarde recommendation, (I’ve owned Duo Omega G2 for 10 years, and still have them)
every point that had been been made elsewhere in this thread is valid:
Given careful set up, They sound absolutely fabulous- transparent, no colorations, dynamic, great micro shadings, non fatiguing.
i use mines with an active crossover and a pair of JL Fathom 112 V2 subs.
Essentially, they are like an audio magnifying glass, you will hear every small change, you make in your system.
I'm sure Trios are even better.
the other very important aspect is- Avantgarde is one of the oldest, largest and best established contemporary horn speakers manufacturers in the world, therefore they have sufficient R&D budget to stay near the top of the game, great customer support and can guarantee worry free ownership, unlike other companies mentioned here, whose presence in the future market place is less certain.

I too, endorse getting in contact with Deja Vu about a custom horn system and also contacting Charney Audio.  The Deja Vu stores in San Diego and Miami are affiliated with Deja Vu in Tyson's Corner Virginia.  If you can find your way to Virginia, you will see where the speakers are made and you will find more options (in any case, you can talk to Vu at the VIrginia store).  With both Deja Vu horns and Charney single-driver back-loaded horns, you have the considerable advantage of being able to utilize low-powered tube amps.  

Low powered tube amps, to me, sound considerably better than either solid state or high-powered tube amps.  But, that does not mean that you cannot use solid state with a horn system.  

I hardly think that the Charney speakers look bad, but, that might just be my particular taste.  They have models that are quite compact which makes them quite easy to place in a room and for their modest size, they sound BIG.  To me, that is a big plus in the "looks" department.

Avantgarde makes nice sounding horn systems that are also quite efficient too.  Certainly, they should be on any short list as well.  They have some quite strange looking systems, but, I kind of like that look.

Good luck on your search.

Handicap is 4.  I am building a somewhat modern home so believe it or not the speakers must not only sound great but must be good looking also.  Boxier vintage style horns will not pass the eye test.  AvantGarde is a contender.  The Uno XD is more in the range of what I want to spend but I have been told the Duo XD are CLEARLY better.  Yes money does matter even in this price range especially when you are talking another $10k.  With my room being about 19'W by 30'L, I have been told the Uno's are not big enough.  I am not sure I buy that statement as my listening area is 12'-14' away.  The Concerto by Charney looks interesting also.  Other than you tube I don't know how it sounds.  

Given your budget, you should consider going to New Jersey (Charney) or the Washington DC area (Deja Vu) to get a good audition.  The other choice would be to attend a show that has some of the brands you are interested in.  Although shows often don't present speakers at their best, they at least will give you more than any description or review can ever deliver.  

Although they are not horn speakers, Voxativ makes systems that have similar characteristics--dynamic, vivid, good at lower volume levels.  Another brand (also not horns) to look into is Trenner and Friedl.  Someone, above mentioned Rethm speakers; I heard their $3,000 model (Bhaava) a couple of years ago and they were quite impressive.  The  Rethm had the liveliness of full range speakers (they use a full range driver plus a powered subwoofer), but none of the excessive peakiness that is common to full range systems).  The Rethm was like a bargain Charney in sound quality.
