How much of High End Audio is Horn Speakers?

I have owned Avantgarde Duos since around 2007, like them very much, have done a few things to improve them and I don’t agree that they are a conservative definition of a horn in many respects- no compression drivers, horn mouths, yes, and hybrid woofers with a plate amp bass. Believe me, nothing said here detracts from what these are, or how much I enjoy them- I don’t think it is accurate to say they define what a horn speaker is-- which, to me, would include horn loaded woofers and upper bass. Alas, that is a more involved topic.

So to be clear, AG’s do not have compression drivers??? I have no idea whats the components ina AG Duo or any of their models. All I know is AG’s have a very high reputation of delivering beautiful horn style music,,, but again, these big horns would not work in my requirements. Its too much of a **good thing** lets say. I listen very near field,,, a the moment,,, when I move in 2 yrs ,,well then sure I will have a hopefully better listening room. But that is one issue with the AG;’s, you need a moderate size room, nothing less than say 15 wide X20 deep, best with a 15 ft ceiling. My rm is short in all 3 dimensions. Horns, REAL horns I’m refering to, need breathing space. As i state above Horns have their issues. Whereas FR can fit in any size room, 8x8x8 to 20x20x20 and sound beautiful. FR Single driver(System, I run dual FR, a single FR would not work for me) have the least amount of issues vs any/all other speaker designs. In my book **least issues * = the superior design.

AG Duos'

make that room  size requirement

40x40x40

Is there an unwritten rule that friends don’t let friends buy Klipsch? ~~~~~~~~~~~~~~~~~~~~~~~~ Yes, this is true.
 

That is rude. 

I have heard the AG Duos in four different rooms, including two small rooms and liked them in all instances.  The bass sounded more even and better integrated in the larger rooms, but there was plenty to like in even the smaller rooms—vivid, lively sound, and reasonably natural tonal qualities.  

Plenty of other horn systems, even quite large systems sound good in small rooms (look at Japanese audio magazines to see how many such systems are crammed into small spaces).  The waveguide of a horn reduces the impact of room interactions and so they can work well in smaller spaces.  I don’t know where someone would get the notion that 15’ ceilings are needed—explain what you personally heard (not youtube nonsense) that is the basis for this claim.
 

Are we refering to the AG Duos in the YT video?

Or another smaller version w/o sub bass??

If we are refering to the speaker in the YT video, I'd say a  rather large size area might accomadate such a  rather huge,,,if not massive soundstage.

Horns like stats need huge areas to breathe,,othwise the listener feels he is being attacked by the speakers.

Small room for a  horn??
Ner heard such a   set up.
