I used the one with the 20Hz Fs.

Response looks about the same despite the differing specs for the 8".

Agreed, a little more "saddle" in the response just above Fb, very slight. The f3 is better than the program gives, also, if you consider an 80Hz cutoff instead of including the rising response over 100Hz.
