After trying a few different center channels speakers I bought a Klipsch RP-450c center channel. It was the one that had the clearest, most distinct dialogue when watching movies. Most of the others my wife and I had trouble hearing dialogue. I think the guide you pointed to ranks the Klipsch R-52C the best. I also have Klipsch Hereseys for my front left & right speakers. I am partial to Klipsch.
