Differences in inductance can, at least to a slight degree, affect frequency response in the upper treble region, especially if the impedance of the speaker is low at those frequencies. Greater high frequency extension = "faster."
Differences in resistance can affect woofer damping and bass response. Better woofer damping and better controlled bass response = "faster."
Differences in capacitance, if extreme enough, can affect amplifier performance, especially at high frequencies that relate to perceived "speed."
Differences in antenna effects, and "transmission line" effects that occur at inaudible RF frequencies, can result in differences in spurious energy that may enter the feedback loop of the amplifier, if it has one, with unpredictable consequences.
There are undoubtedly other reasons as well, although not necessarily the reasons that are stated in the "white papers" of some cable manufacturers. And none of these reasons necessarily mean that "more expensive" = "better."
