I suspect the upper bass "bump" is a classic technique to give the impression of more bass than there really is, subjectively. The classic example of this is from JA's reviews of the LS5/3a:
"but it can be seen in fig.3 that the woofer's response peaks by about the same 6dB in the upper bass. This is the classic "LS3/5a bump," which gives the impression that this little speaker produces more bass than it actually does. However, this bump will make the speaker sensitive to excessive boundary reinforcement when not used in free space."
Further up, I suspect from Amir's measurements that the subtle peak around 1khz will add subjective detail, and the 2-3khz dip, though a bit lower than the classic BBC dip, will be subjectively pleasing to many listeners (who may not know or care how it measures)- see classic Spendors, Harbeths, others.
So while they are not as linear as many of the studio monitors measured on this site, it is certainly possible they would be enjoyed by many music lovers. They might feel that all small speakers involve compromises and think that the compromises chosen in these are worthwhile.
