Although the Klipsch web site doesn't specifically say so, I don't believe that those surround speakers are Dipoles - two highly directional horn drivers and a single woofer pointed at the listener (and a crossover frequency of 2kHz) - only the high frequency sound could be out of phase.
More likely they are a large angle baffle Bipole - which is a lot closer to a direct radiator than a true Dipole (which has no direct sound from the speaker). Many people prefer direct radiators as surrounds - especially for multi-channel music. There is no right or wrong, it is really a matter of personal preference. If you like direct radiators for surrounds then go for it.
Are you placing them 3 feet above the seated listeners ears?
