Horn based loudspeakers why the controversy?

In response to the OP, I think the 'controversy' goes back quite a few years, when the majority of commercially available horn speakers had a honky, nasally sound.

I had this impression myself, from years of working in mid-fi and only being exposed to what was available at that level. 

More recently, I have had the pleasure of hearing quite a few of the high end horn speakers (Avantgarde Acoustics, Cessaro, Acapella, and others) at audio shows, and my mind has been changed.

Just an FYI. Peter Noerback, of PBN Audio, introduced recently, a " horn " hybrid loudspeaker, using JBL pro drivers. He has used all of his listening and engineering prowess, to build a cabinet and crossover, to accommodate these drivers, resulting in, what he says, is the " best " he has ever designed. I think this says a lot about horn designs. Reminds me of the Epic CF4s I was owned ( although a D' Appolito design ) as, they have been mentioned in this post by another, claiming of all the speakers that have come and gone, these has stayed the longest, and he gets the most satisfaction out of them. No one here is claiming that horns are perfect ( I sure am not ), but I still say, with all else being excellent ( room, equipment, tweaks and such, horns do more good, than bad, in recreating a live musical event, if this is the sound you want, and this, is what you feel it should sound like ( of course, still personal ). Still, not for everybody. I value listeners, of all backgrounds and experiences, to select what they like. Again, this is what our hobby is all about. Sorry for my posts today, I suppose, I am in a passionate mood ( unfortunately ), I do not have a woman with me at the moment. MrD

I should have " prrof " read my last post, as I see some errors, lol.

Can you suggest a few good horn models?

I did something quite unexpected.....   I auditioned a pair of Klipsch Heresy lll.....   and I ended up taking them home.   With a good sub they sound fantastic and are the closest thing to live music I've ever had in this room...
