That's funny, as the last salesperson was trying to sell me on Paradigms, and when I had him A/B switch between the RF-82s and the Paradigms, the bass disappeared and the overall volume dropped by about 6-8dB. True, the bass was muddy and loose on the RF-82s because of the crap-@$$ receiver that was powering the speakers, but if I were a hip-hopper I would have put the Klipsches in my car and called it a day.
I remember a very good Klipsch dealer in Chicago that kept everything in stock, from the smallest of the Reference series to the top of the Heritage series. The amazing thing was that when you went from speaker to speaker (going up in size/price), you just got MORE. The sound quality didn't change, but the amount of bass and the overall amount of sound just kept building. By the time he got to the Khorns the sound was just amazing. I brought in my own discs for him to play, some of which were classical, others more modern, some with a LOT of bass. The Khorns did a fantastic job of all of them. Then we put on Saving Private Ryan, and the Khorns again delivered realistic sound, even in the opening battle scenes.
Truth be told, I use a JL Audio F113 sub with my Klipsches. That sub matches the Klipsches extremely well (oddly I was disappointed by the RT-12d). Together the reference system and the sub have some of the best sound I've heard for less than $20,000.
