I'd go with the RB-61 II. They are direct-radiating and driver-match your front speakers.
I don't have a Klipsch setup, but I driver-matched my DefTech setup with very good results with nearly seamless sound movement across the front sound-stage.
Good flicks to test your new setup on are The Avengers, Expendables 2, and Oblivion using DTS Neo:X processing.
HD-DVD = 94
Blu-Ray = 120 ( 24 Warner red2blu )
