Fender Blue Label Speakers in 212-130

I just got a 212-130. It has Fender Blue-Label speakers in it. Sound Good, but just wondering if these were stock or add-ins. If so, Will it sound better w/other speakers ? What do you advise ?

Someone correct me if I'm wrong but I don't see how these could be original speakers in a MM amp. If you read the history of MM amps on the main page Leo Fender wouldn't have been allowed to put those in a MM amp. I was told the JBL in my 112 RP 65 was not stock coz Fender used them as well and that would have been infringement on MM's part.

yep
eminence were stock
or EV's if you were willing to pay a little extra

I have 4 Fender Blue Label "Special Design" 10" drivers in my 410-65. I put them in there as a low-cost replacement for the blown wimpy originals.
From what I have discovered, all the Fender Blue Label "Special Design" speakers are OEM units from Eminence.
I like these speakers as well as the Eminence-branded units they resemble, they just happen to say Fender on them.
