Definately 2 different camps on this one! Personally, I find they irritate my ears, literally I find that my ears sort of itch internally after listening to them. Other speakers rate frequency response +/- 3db, Klipch (at least used to) rate their speakers +/- 1.5 db. They have no where near a flat response. Like all things in audio, there are comprimises. Where they give back is in effiency and dynamics. I have a SET amp and frequent such web sites where there are a lot of Klipsch fans. The fact that some of their older speakers are still going strong supports the fact that they are well made. Personally, I do not think I will ever own a pair. I am leaning towards a DYI/Fostex based speakers next time around.
