To understand why Klipsch speakers (whether K-horns or Heresy) are so polarizing it is important to recognize that most all speakers do SOMETHING well. I feel I can speak with authority about the Klipsch corner horns because I owned a pair for 8 years in the '70's in a 30' room driven by everything from an Advent receiver (15 wpc) to a Crown DC300. What they had was dynamic range. Compared to the acoustic suspension speakers that were in fashion at the time the horns jumped out at you and had a HUGE presence. They were really a PA speaker, like many JBL's. The midrange would become very fatiguing in short order and the highs were like razor blades across your eardrums, but they filled my room with effortless power, even from 15 wpc. My friend, a trombone player, had Heresy's (and still has them). He likes them because they accentuate the frequency range the trombone occupied; warm and woofy. You pays yer' money and you takes yer' choice!
