All speakers have a little EQ built in

It may come as a shock to audio purists but part of the work of a crossover is level matching as well as tonal adjustments of individual drivers.  Ahem.  That's what we call equalization. 

This is true whether the speaker uses active or passive crossover, and may be in place just to adjust phase matching in the crossover range.

Also, curiously, while companies may brag about the number of parts in their crossovers, more parts does not indicate more quality.  It may just indicate more equalization had to be done to the drivers to get them to match.
