How do Klipschorns compare with modern designs?


I'm curious to hear from those who have seriously a/b'd Klipschorns with comparably priced modern designs. I am most interested in comments regarding soundstaging and transparency.

Thanks.

Got a  pair of Heresy IIIs a little over a year ago and I can say with certainty they display none of the characteristics mentioned by sean...luckily! Whew...
In University, U of T,  I spent a lot of time a Bay/Bloor Radio. A good Hi End Audiophile store. They had a large bias against Klipsch, Altec, JBL, They would  say Junky But Loud. I had a Cheap Trills Concert Pass and saw all of the big Acts of the 70's and early 80's.  When you go to a live concert what are you listening to? A large PA system. You want to produce a live like sound at home, bingo, Klipshorns and all the horns sound great, live, dynamic. If you like Jazz? a Horn sounds like a horn coming out of the horn. What is the human voice, a small Horn. People who are posting negative comments, want to listen to a Stereo sound,  Khorns sound very live. The imaging is great, but the sweet spot for optimal listeningn is small. When I give a demo, I give people my media chair that I have dialed in.  My present set up is the smallest room they have ever been in, and I am always anxious to get to my sweet spot.  I installed a second Horn Tweeter to my  Sweet spot, from both cabinets.  Do your homework, go listen to systems. If you want one of the best live music experiences give the khorns a earful. 
I love Klipschorns and have owned them twice. They sound different than more modern speakers, being more dynamic and IMHO from the midbass up they are quite transparent, below that less so, but not to a disqualifying degree.

Cant comment on the soundstage thing as I find it to be a trick and something I do not hear in the concert hall. So I don’t listen for it. But, since Khorns must be used in the corners of the room, in certain setups there can be a hole in the middle effect. In recognition of this Klipsch suggested a single Cornwall to go in the center, on the wall between the Khorns. Of course this necessitates having a third amp channel with variable gain to match the less efficient Cornie to the Khorns.

Seems like a lot of work but I loved this setup. Corners with less distance between them obviate the need for the center channel however.
