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.
Denon AVR X7200WA, Emotiva XPR-5, Emotiva XPA-7, Sony XBR 75" 850C, Oppo BDP-103D, Roku 4.
DefTech BP7000SC (L/R), CLR3000 (C), SM55 (FH), UIW BPZ/A (SB), UIW 75 (TM).
JBL L7 (Sur), EoSone RSR 350 (RH).
PC 2.1 setup. Emotiva Stealth 6, SVS SB2000 sub, Emotiva DC-1 DAC.
