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

Was talking with a European speaker rep about a new diecast basket I said cool you mean like hotwheels use? 

@bdp24 phenomenal post!

Seems to me Wilson uses a number of drivers made by MISCO of Minneapolis. They often make custom drivers and have been in business for decades. Experience working with materials is worth something; its often all about execution!

I only have a brief comment to make here, but one i feel future speaker buyers might want to consider.  Foam surrounds do not seem to survive well in wet, sticky climates (like Florida for instance). Apparently they can still be found in some expensive products, as I can attest to from personal experience.  I was able to replace the speakers with identical designs but now the manufacturer substituted rubber surrounds.  I believe some of the Watt/Puppies way back when also used foam and had to be repaired or replaced after a few years.

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.

Good Listening
