Both the one π and the two π speakers are excellent as surrounds for three π or four π mains. Each has the same spectral balance, and so they preserve the illusion of seamless, fluid movement when sounds pan from surround to mains or vice versa.
Really then one π and two π speakers are more similar than different. You could almost consider them to be equivalent speakers, certainly above 100Hz. The only real difference is below 100Hz, where the two π goes a little lower.
