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?

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.
Aerial Acoustics has never produced their "own" driver either and yet has managed to create some amazing speakers.
