The difference is the combfilter destructive cancellations that create sharp narrow nulls in the frequency response.While these nulls are too narrow to be heard directly, they combine to create what many describe as a "more spacious" sound quality compared with the point source of a mono center speaker.
A mono center speaker is better for a center vocalist.
This was discovered in the 1930's when Bell Labs decided three speakers were the minimum for a stereo effect (left, center and right) but later no one could figure out how to put three channels on vinyl, so we got a two channel compromise instead.I have experimented with center mono versus stereo vocalists going back to the late 1960's ,long before surround sound. The most natural sounding solo vocalist will be from a mono speaker on a tall stand aimed down at the listener (simulating a singer standing and singing in front of a seated listener). Of course common sense would lead to the same conclusion.
If the sound of direct radiator speakers seems shrill, then pad down the treble output of the front tweeter, place sound absorbers at side wall reflection points and listen off-axis if there's still too much treble -- there's no need for rear tweeters firing at walls. They create early reflections off the nearby walls that can never dupicate the ambience (reverberation) in a large venue.
