Don't get caught up in the crap surrounding sensitivity and how it is measured. I have personally owned a set of Polk Monitor Series II and recently moved to the Klipsch Reference line and I will say definitively that the Klipsch speakers are much more detailed and fuller sounding with movies than the Polks. I have also noticed how much louder they get without distortion with movie cues such as explosions, gunfire, crashes, etc. One scene where I noticed this the most was the train wreck scene in Super 8. The polks had a bit of distortion in the sound where the Klipsch speakers brought it home with full force, loud and clear. I just don't want you to pass up on a nicer set of speakers because someone doesn't like how Klipsch markets their sensitivity.
