Silverface Twin reverb-wat speakers do i hav?

I've looked all over my speakers and can't find any hint as to who made them. The only thing written on them is "Fender Musical Instruments - special design speaker" - blue label on the magnet with silver lettering. Inside the chassis everything is dated 1975. This also has the infamous master volume with pull switch. 100W amp.

I'm about to get the speakers re-coned as both have small cracks and are starting to buzz on certain tones. Is this the best option or do I replace with something new? The amp repair tech(who I really trust) suggested I just re-cone them as it would make it more valuable to keep it as original as possible. Just wondering how much of a different sound and upgrade would make. Actually, it will not be original anyway as he is blackfacing it too.

I have the same amp and the speakers a probably Oxfords and they really don't sound very good IMHO. The amp tech I used loves working on Twins and recommended that I replace the one speaker with the new Jensens that are in the current TRRI and the DRRI (C12K) and it made the amp open up. It sounds much better than the stock speaker still in there so I will definitely replace that one soon. The amp used to belong to my Uncle and he is not doing very well health wise so I have no intention of selling it but I am holding on the original speakers.
If you are using this as a gigging amp you should get anything replaced that will make the amp sound great and functioning. Don't worry about keeping original. You can always hold on to the partes that were replaced and put them back in before you sell it.

ps: Dime the master volume and just use the channel volume. It sounds much better.

Thanks. Good point about sound vs value. Anybody know of a good source for the Jensen's?

Some of the blue speakers from that era were Utah. is there a numbered code on either speaker. That would give source of speaker, and year of manufacture.

The numbers stamped on the outer rim of the speaker look like this
005379
328604

There is also an upper case "M" with a circle around it further around the rim.

Other than that as far as I can tell no other #'s anywhere else. I'm surprised they moved at all with as much dust as I'd gathered in them over the last 25years.

I think that's utah 1976 328=utah, 6=76, 04=4th week

IMO, neither the Oxfarts or Utahs from that era sound very good. Fender was buying speakers from the cheapest supplier they could find, you get what you pay for.

For a 100W Twin, your best bet would be a pair of Weber high power series speakers. Go with Californias if you want a JBL vibe, go with Chicagos if you want a Jensen vibe.

+1 They're Utahs.

If you want to go rright through the amp, you can date almost every bit. Just like guitars, they tend to be a complete mixture.

I think Utah speakers get a bad rap.
Can't say the same for Oxfart speakers though.
I personally like the Weber's over the Jensen RI speakers.

+1 on the Utah's. I often wonder if all the folks who dis them have ever actually spent time listening to them in a Twin or are just parrotting what they've read in another post.

I can say from experience that they are not very good sounding speakers. Of course it took a change out to hear the difference but the original speakers were kind of poopy.

I can't speak for the all the folks but you can say that about every product that gets praise or scorn on these posts. It is part of the terrain.

I'm not familiar w/either the Jensens or the JBL's. Is it possible to make a generalization about the sound of the Chicago's vs California's?

Thanks guys for i.d. ing these. May just recone and use them.
Definitley weighing the pos. and neg. utah reviews. Any one else have an opinion either way?

JBL's were pretty much used in the Blackface Twin Reverb's.

Are those Alnico or Ceramics?

This particular amp has always sounded thin/harsh to me. For years my main guitar was a 76 deluxe with mini-humbuckers. I'm sure that didn't help with the sound. My tele does sound better. Hoping the blackfaceing might warm it up a bit. After reading through some of the info tazzboy sent I'm wondering if the Utahs could possibly have contributed to the harshness? IDK? What speakers should I stay away from...or what speakers might help to warm it up?

I'd say go with Ted Weber right now he is offer 10% off most of his items including speakers I would tell him what you are looking for sound wise and go with what he recommends

The speakers in my 73 100w SFTR are marked 020910 67-8403.

What might they be?

Emailed Mr. Weber yesterday and already received his reply and suggestions. Hoping to place an order tonight.

I'm guessing Eminence, because it's the only thing I can think that could match: http://www.webervst.com/morecode.html

Well what did Ted Suggest?

Yeah those are Eminence Speakers.

Those are ceramic California speakers, called C12CA at the time, I'd recommend the paper dustcovers over the standard aluminium.

Well what did Ted Suggest?

A mixed pair.
12F150 and 12F150B, lightly doped.

Cool. Those I Know would be really good ceramic speakers.

I think you're right because of the 67 speaker code, but what do you suppose the 8403 means - it doesn't seem to follow published examples of Eminence codes?

Alright, I finally ordered them tonight. Now, I'll have to chill and work on my patience. Will be using my practice amp for everything until they arrive. Princeton 112+. Solid state and ok through the clean channel but not like playing through my twin. Should get the blackfaced twin chassis and reverb unit back sometime this week!

My guess is the year and week the speakers were manufacture in.

I am looking at buying a 1968 Silverface Twin Reverb and also wondered what speakers are in the amp. They also only say "Fender Musical Instruments" and have a blue label. The only marking is a partial number of 105379 as the numbers below this are worn off. Does anyone know what type of speaker this is? I am pretty sure, through research, this is truly a 1968 Silverface Twin Reverb. Thank you for the help.

Good day today. John called to say my chassis was ready, weber speakers arrived at my door via fed Ex. They are now in, amp is blackfaced, and I am happy.

Some of the best $ I've ever spent gear wise.

Glad you like it. Is there any chance with pictures of the upgrades?

Btw, I'm pretty sure if it has the boost it's 135 watts.

I apologize for not posting this sooner. Life's been happening here. My wife is pregnant and has had morning sickness 24/7 for the past 12 weeks. oh yeah, finally found the camera too.

Looks good

Hey, thanks again tazzboy, I might never had happened upon the weber's had it not been for your suggestion. I'm really happy with the sound of this amp now.

Well your welcome. All I did was make a suggested on who to go with. Ted deserves credit in suggesting the right speaker to work with your amp.

Thanks Ted!!!:grin:
