RE: Frontal Horizontal Directivity Measurements of a speaker ?..

The interaural crosstalk approach depends on having the information arrive intact at the listener's ears and so most effectively cancels out the crosstalk from one ear from the opposing loudspeaker.

The preservation of information is also of interest when understanding random words is important and in that situation, what is known is that reflected sound within the ITG (initial time gap) harms the ability to understand those words as it corrupts it with Echo's of the original signal.

This is backed up both by measurements and tests using random words and the reason can be seen examine the Modulation Transfer Function measurements used to measure/ predict speech intelligibility.

In the case of a perfect reproducer with high directivity, a soft voice, fed as a mono signal fed to two coherent equidistant sources / speakers will produce the effect of a voice coming from directly in front of you as if a person were standing there with no awareness of a right and left source.
At the opposite extreme of incoherent sources with lots of energy within the ITG , there will be a very clear right and left source with the impression of some sound coming from between the two or even as a wall of sound between the two and not a single phantom source like a person standing there talking.

Home stereo is a situation somewhat like a musical instrument producer where whatever is pleasing is good and a window into another acoustic environment not always desired.
