It may not be true of the newer vehicles, but from past experience, Ford factory speakers have plastic frames and less than spectacular magnet assemblies. My 2011 Expy King Ranch El is an example. Two very important factors of speakers are frame rigidity and strength of the magnet for controlling unwanted cone oscillations. Even with "name brand" head units, Ford seems to put cost ahead of quality when it comes to speakers. Pretty much any reasonable quality aftermarket speaker is far superior in sound reproduction, range, and accuracy.
