If programs implementing the T-S laws are so good and allow such a good
understanding of how the enclosure and related issues affect sound, then
should not the determining factor differentiating speaker designs be the
driver design itself?

The equations dealing with the T-S parameters do nothing more than deal
with the way the fundamental spring/mass resonance of the driver interacts
with the enclosure to form a high pass filter. They have no relationship to
the sound of the drivers outside this region. All of that is still a matter
of manufacturers making good, flat drivers.

The T-S parameters can tell you the required volume of the enclosure
and what shape should be the port, but they tell you nothing about the
internal dimensions, shape or resonant qualities of the enclsure, all
of which are just as important as the drivers.
