How can Wilson Audio speakers sound that good if they are using OEM drivers?

The ScanSpeak Drivers used in most Wilson Speakers are excellent drivers - they could be somewhat customized too specifications set forth by Wilson.  The 4" midrange driver used in the new Wamm is a beyond excellent midrange driver with a foam surround and a paper cone.

In speaker design its always about how well one makes the drivers, cabinet and the all important crossover design work as a whole.

Here is an example of a 40 year old woofer design integrated with a very recent Midrange/Tweeter Driver on a waveguide - this thing will run circles around any conventional speaker using a 1" dome - what ever its made from, and yes I made it :-)

I don’t recall any Wilson with a Focal midrange driver - the first ones used a Seas inverted surround - Focal Kevlar tweeter Dynaudio poly woofers - which maintained through the whole WP thing. 

From the WP5 up the midrange was ScanSpeak 18Wx5x5 and the Focal inverted laminated TI dome.

That used to be the case, nowadays the foam surrounds should have been treated with "moldcide" which will prolong the life of them.  Its mold that cause them to deteriorate.  Further more the ones on the 4" ScanSpeak driver in discussion is coated on the front side.  The advantage of a foam surround compared to a rubber one is that it does not get "stiffer" as frequency increases which is one reason its being used on this particular driver   

Rubber surrounds too do deteriorate the process however takes longer.
