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


How can Wilson Speaker sound that good if they are using OEM drivers made of last century materials? B&W used Kevlar and now Continuum, after a lot of R&D. Magico uses Graphane which is the new Carbon Fiber. 
Would a Wilson Speaker sound better if somehow one could put a B&W midrange Continuum driver instead of the OEM paper driver they use?

Lots of high end speakers use paper pulp woofers because they are lighter, (especially for larger drivers.) and offer better reproduction of live instruments and music.  The “paper pulp” each manufacturer has is a closely guarded secret recipie usually a composite.  As for using other brands for their tweeters and mids for example.  They usually have it built or modified to their specs.  It’s like hiring the best company for the job.  For example in the past focal made tweeters for them, then they moved onto scanspeak (from Denmark) making their tweeters to their spec.  Often even when a specific tweeter model is used the speaker manufacture will have it modified slightly or customized in some way to make it their own.

OEM drivers work great but the cabinet and the crossover are an equal part of the sound.
Aside from the obvious logical errors in this post I just want to explain something the OP fails to understand:

The worst Wilson sounds better than the best B&W

This is indisputable.
