Depending on the value of the coil, the series resistance introduced by it can be approx. 50% higher for the 16 AWG version, which in turn alters the Qts value of your driver, also causes higher loss in sensitivity. If you calculate your box size and tuning with a software that does not account for the series DCR of the filter coil, this can cause problems.
Ok cutting to the chase... As one takes a low pass crossover point higher the size of the inductor wire has influence. At 1K or so... not all that important... but as the mid woofer is asked to play well into the mid range... the larger inductor wire size has considerable influence... So.. if your mid woofer is required to play much above 1.5K or so... go with the 14 ga.
John Busch,
the wire diameter has no real importance in the way you are talking
about. The greater dcr of the coils can cause two things:
1. attenuate bassmid driver by a very small amount, typically
0,15 ohms more dcr will shift the level down by approx. 0,25 dB
2. slightly increase the Qtc value of the driver installed in a box
The inductance is a major player when it comes to make influence
on frequencies, not wire thickness, as long as we are talking about
normal values of coil dcr's.

Lojzek,
Your comments are correct of course... I should have been more specific in my post... it has been my experience that larger wire diameter inductors, especially larger value ones SOUND better at mid range frequencies. It is not a measurable thing. George Short (North Creek) and others have also observed this. You can see some very large values in mid range band pass 2nd, 3rd and 4th order 3 way passive networks, especially at 500 Hz or below. YMMV of course!!

John Busch,
thanks for clarifying things on the matter. Appreciate it. I did
check North Creek Audio site and found about service they provide.
When it comes to using higher order filters like 3rd, then it makes
more sense to use thicker wires.
Let's assume one would want to upgrade inductors in a hypothetical
XO filter. A serious manufacturer would use about AWG 13 but for
the sake of getting the most out of it, AWG 8 looks interesting.
