that is a great example-- pyle vs. focal utopia....
actually, i think you bumped into the problem-- the responsiveness would be the killer.
the pyle is going to be sloppy while the focal is going to maintain it's composure longer
the first question i have is can you reign in a sloppy driver with only a eq?
different listening volumes would also play a part-- a low volume might not reveal any differences, but once you start cranking it up, and really pushing the limits of the drivers, you would need to re-eq..
part of it is the way the drivers are made, i imagine that pyle has looser manufacturing tolerances then a high end company like focal
so those tolerances affect everything-- the magnetic gap might be larger on the pyle, which equals less cone control.. or the cone might be a couple grams heavier then originally spec'ed, or the spider might be something off their shelf that fit the build instead of something that is designed for the rest of the speaker. i believe that many of focals drivers are built by hand, so they are held to a tighter tolerance, and in a speaker like the utopia, they would custom design all the parts to work together-- so the spider, and cone, and coil are all meant for THAT speaker...
(even if it is beating a dead horse, i like discussing theoretical topics )
