The Klipschorn uses an exponential horn. Tractrix "De-Balls" the horn sound making the horn speaker sound more like a conventional speaker. People who like more of an "in your face" horn sound prefer exponential horns and people who prefer more of a "wave guide" type horn like tractrix. I have owned countless Klipsch speaker lines over the years both professional Klipsch speakers, Reference lines, Heritage lines including LaScalla, Klipschorns and I prefer exponential. If you like a horn to sound like a horn then exponential does the job best and if you prefer a more conventional sound you may as well get away from horns altogether and go with a Kef speaker in my opinion.
