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?

"Last century materials", sitting here listing to a pair of speakers, not Wilson Audio, made of plywood with paper and silk drivers. So last century but damn they sound good. What sounds best is not always what's newest, sometimes it's what's oldest or somewhere in between.
I'm no Wilson fan but in my opinion the exotic materials used by some companies are about talk rather than performance.  I had B&W for a long time and when I moved on I was kind of angry that the aluminum drivers of my new speakers sounded so unmistakably better than the fun to talk about but not very good sounding Kevlar. 
Exotic and new obviously doesn't equate to better sound. Vintage speakers from Altec and JBL etc. are proof of that. Besides, a loudspeaker is a system whose performance depends on a balance of driver, crossover and enclosure design considerations. You must already know that.
