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.
