Here's another plot w/o the lowpass filter:

and here's the same, but anechoic(no cabin gain):

Yep, I agree. Anechoic response plots aren't very helpful. From looking at the last plot, one would think the 10w0 would be the best choice, but I can tell you from experience it doesn't play very low w/o help from a PEQ.

To give you an idea of how "flat" the sealed curves really are here's my 10w3's(3.25 ft^3 common @ 28Hz, green) along with the others:

I'm pretty sure those plots aren't very accurate below 30 Hz as my 10w3's low end extension doesn't seem as good as what the plot would indicate.

I figure the actual response is somewhere between the anechoic plots and those modeled with cabin gain. Still WinISD is the best thing I have so far especially since I don't have the equipment necessary to accurately measure my vehicle's transfer function.
