Once we get far enough away from the speakers that the reverberant field dominates over the direct sound, it really doesn't matter whether the sound originated from a point source or a line source. And by the time we're outside the main listening room, the 3 dB per distance doubling falloff advantage of line source propagation is disrupted anyway.
Imho more important than line source vs point source propagation is the off-axis response smoothness, which will establish the tonal balance at greater-than-normal listening distances, whether on-axis or off or in the next room.
