My EII's woofers are Vifa M21WN-7 4ohm. From the looks of the rot and discoloration of the sticker, I'm going to say they are original. However I cannot be 100% certain as I am not the original owner.
Also, keep in mind that Snell made changes which can sometimes be linked depending on production-s/n's. The Vifa's mentioned above may have been available during the time of the original post, but will all likely be Seas if replacements are bought though Snell.
The good news is that last I checked, they are still servicing and may actually be able to answer drivers used in production depending on your personal s/n. The price isn't low, but they are still testing these drivers to the master and mailing a replacement inductor with each driver.
