Ok, that's fair. But do you believe the Polk 'speaker's claim on it's sensitivity? My guess would be that the two manufacturers list their claimed specs in a similar manner which still puts the Klipsch ahead for output. Once again, as I suggested earlier, the OP should go listen for himself and buy the one he likes better.
