Ooops, sorry I missed this part of your post.

it's using a hypothetical position to level the field somewhat;
otherwise (as is the case in the real world) you'd have to take into
account the nonperfection of that lower part design and the
problem of assigning differences to differences-in-the-tweeter
is compounded.

Playing with the "nonperfection" is full part of the game this is why I
don't want to play with your original postulate. :-)

what i'm really getting at is that at this point a builder can say:

"in the end i chose brand X model Y because it sounded best"

Because it is better matching the temporary, unstable and fragile
"perfection" that I think I have reached.

but that doesn't tell us much, does it ?
there are many different aspects and unless there is the very
unlikely case of a clear 'winner' in all categories evaluated,
it is a weighing game say less distortion vs. better pulse response
a small high frequency dropoff from 18 kHz but flawless dispersion
vs. ruler flat on-axis, but lousy dispersion,
etc.etc.

The DIYer, when armed with tools, time, etc.,
is at an advantage here - he can set those weighing factors
himself (m/f) ;-)

Don't forget "passion".
And if in the end you can share the fruit of your pleasure with others
listening some music...
