I've listened to the Klipsch RF-82s and I liked them.
Even the $22,000 Klipsch towers don't have a flat on-axis and off-axis frequency response as measured by Stereophile.
So I'm thinking that Klipsch are kind of like DefTech where the number one priority isn't about achieving flat on-axis and off-axis frequency responses. I've listened to Klipsch speakers before and I've owned some DefTech speakers in the past, and they kind of sound similar to me - very energetic and lively sound, not to say that they sound forward, but just exciting sound.
Just like other speakers out there, not everyone will like the sound, even if the speakers are $22,000.
