I'm not an audiofreak but I was looking for a better system than the lower end home theater 'box' setups. The sound is excellent for my medium size room. Set up is easy but I would recommend they have information on suggested wiring, etc., instead of my having to researching the subject.

Great Sound with my Yamaha Receiver. Prior speakers just didn't do receiver justice
Immersive Base; Buried Dialogue
The surround speakers (the 4 small ones) put out an amazing amount of bass. The system as a whole (I evaluated it with the 10" sub since the 8" happened to be DOA) sounded just like the theatre presentation of Walter Mitty that I just saw--lots of bass but muted high-mid to treble. (I assume this theatre did not have a Klipsch system.) The Definitive Technology system's bass is clean and strong and mesmerizing if you prefer movies like Men In Black (the worm in MIBII sounded like it would come up through my living room floor) or action/explosion movies. Ultimately though I could not live with the lack of higher frequencies--dialogue was muted, music was unbalanced, and for the dialogue-rich movies I prefer Klipsch turned out to be a better match.
One other note: in using these with a Marantz 100w/channel receiver, one musical passage made the surrounds clip quite noticeably. I suspect to get the dynamic range movies require, big amp power would be a good idea.
