Fender doesn't manufacturer these speakers..... They make a 412 cab.
Celestion does make these speakers and they label them as 20w on the label and spec sheet.
Now anyone is free to buy these individually from them or a retailer and follow whatever rat/bat shit logic you care to argue here all day..... Or follow common sense and avoid warranty issues and potentially blowing up your speaker and amp and avoid losing hundreds if not thousands of dollars by mishandling and misuse.
Me I just follow the label and common sense but anyone is free to do whatever you suggest, listen to shit on the Internet and Forum bro logic and take the risk..... I'm no "expert" like you buddy and that's above my pay grade.
Anyways as said before...... Just let it go...... Let it go.... Let it go
