Fender has used only a handful of different speaker types over the years.
Here’s a list of brands along with their EIA codes.
Here's the specs from the new re-issues which are comparable. Easy to remove if you decide to use the mounting flanges.

Whether it’s a vintage amp or a recent model such as this Fender Pro Reverb, hum can have several causes.
Possible culprits include the preamp tubes, the power tubes, the hum balance resistors, and the power supply caps.
I have a 1965 Deluxe Reverb and am trying to figure out if it has a Utah or some other kind of speaker. I also have one of the newer Fender Pro Reverb amps with an effects loop and a silverface Twin Reverb with a volume control. Steve Goldner San Diego Hi Steve, Thanks for your questions. Figuring out which manufacturer’s speaker is in your amp shouldn’t pose a problem unless it’s some aftermarket mystery speaker with no markings.
I was thinking of trying a Celestion Gold 50, but I usually only play in my bedroom, and I don't want to increase the amp’s volume. Both amps produce very loud hum whether or not a guitar is plugged in. Or is there some other possible cause you can point me to? Most factory speakers in Fender amplifiers have what is known as an EIA code that specifies their manufacturer.
The SPL rating specifies how loud a speaker is at a distance of one meter when driven by one watt. I don’t know what speaker is in your amp, and even if I did, its specs might not be available.
(I’ve also included a few others brands you might encounter as aftermarket installations.) This should help you identify your speaker.
You also mentioned that you’re looking for a speaker option that decreases the overall volume of your amp.
Our "parts units", parts / spares and related reference information are primarily archived for the purpose of restoration / repair of "Oak Tree Vintage" units first.
Only if we do not have a "viable" unit in yet, either already in process or in line to be processed, that may potentially need parts from a "parts unit", will we release available parts for sale (even though they may appear as available for sale to the public).
The alternative to all of the above would be to not offer them at all to the public, however most parts are available to the public for sale.
