All Celestion speakers have a model number denoting their specification, usually beginning with the letter T. This apparently represents the word ‘type’. Speakers with the ‘CT’ and ‘RT’ prefix are said to represent ‘Rola type’ and ‘Celestion type’.
A letter ‘A’ or ‘B’ after the T number can be overlooked. This is for internal use at Celestion, and they have asked me not to publish what it really means. For example T3904A and T3904B are both speakers made to the same specification.
The T-number list below has been compiled from various sources, and I have tried to keep it focused on guitar speaker models.
If you are looking for information about vintage Vox related Celestion speakers, check out the Vox Supreme website run by Nicholas Orchard. It is very regularly updated with new information and is fast growing into an excellent resource!
Share your Celestion T-numbers!
If you know of any Celestion t-numbers that are missing from the list, or see anything that needs altering, then please email me, or add a comment at the bottom of the page. I will update the list accordingly when time permits. Guitar speakers only please.
Please try and include as much information as possible including cone stamps, impedance, and power ratings, the amp or cab they came from, and ideally some photos. The more info the better. People do email regularly to tell me what a useful resource this is, so lets keep up the good work and keep sharing the knowledge.
Big thanks to everyone who has contributed so far, with special thanks to the members of The Marshall Amp Forum. Thanks to ‘GIBSON67’ in particular for his huge list. Thanks also to ‘Jeff West’ for his 10″ and Vox speakers list.
Please remember that Celestion speakers evolved through the years. Certain details such as cone stamps and other part numbers, may be different depending on when the speaker was made.
The list is now searchable and sortable. Click a heading to sort by that column, or use the search box to find your speaker model. Enjoy!

Hi, thanks for the info. It has been added to the list.

Ok added, thanks for sharing.
What about the 16 ohm V30 T5225 and 8 ohm V30 T5273, both carrying the cone stamp 1777? Probably not an error: official photos depict this stamp in clear view, as if to point out it was intentionally made with this cone.
Author
Hi, thanks for the info, I will add these to the list. A lot of the more recent speaker models with the higher T-numbers are missing, I still need to add them.
regards, Brian.
Cheers, mate! Just figured since there’s a consensus that V30s always were and always will be 444 cones. Anything else would be chalked down as a factory misstake with stamping the cones incorrectly. Not so the case here, it would seem.
444 is a Bass cone, and 1777 is a Lead cone..
8ohm Celestion-branded V30
Ipswitch Suffolk England label
NO side sticker or trace thereof
Beige-goldish frame
Small vent hole without mesh cover on back (about the same size as the “o” in ohms)
Cone stamp: 444
Frame stamp: 26AL T3903/2.
Origin unknown, bought used, claimed UK iirc but who knows
Wondering about the slash-two-period (T3903/2.) in the model code, anyone know what that’s all about?
T5356A – 8 Ohm – G12-412MG – Apparently these are 30W.
Author
Hi, thanks for the info Andrew. Some T-numbers have additional digits appended to the end such as letter ‘A’ or ‘B’. I’m not sure what their meaning is, but pretty sure they are basically the same speaker regardless. Looking around online there seems to be conflicting info on T5356 power rating, some people say 40w, some 35w, and some 30w.
regards, Brian.
Yes im curious about the A or B. Also ran into one with an AR. Can anyone shed light on this? T3904.

T1920x EJ24 G12H..75HZ SMOOTH CONE..BLACKBACK…THINK ITS 24 MAY 76..NO INFO ON IT ANYWHERE.
Author
Hi Richie, can you email me some photos? the x is just an inspection character or factory code, not part of the model number. They added it to the end of the model number for a short period in the mid 70’s. So the model is T1920. It is on the list as “PS12, ceramic, 8 Ohm, 20w, red/white label – twin cone.” Have you tried emailing drdecibel@celestion.com? They should be able to tell you more.
Brian.
Hi Brian it’s a 30w not a 20w..
Author
OK thanks for the update.
Author
Actually, can you email me some photos of your speaker please? Something isn’t right. If you do a google image search for “celestion ps12” there are a few examples of T1920 that show up and they are all 20w on the label. So based on that I will have to change it back to 20w. They are not a H magnet speaker either. Yours may have a smudged code that you are not reading correctly? I need to see it really.
What’s your email brian

Hi, info@bygonetones.com
thanks, Brian.
A topic often missunderstod and miscredited as defense of the G12T75 devider is the transition from the G12-65 to the early G12T75s. Now on various online-forumes I’ve tried to tell this story to my best abilities. However not knowing the exact details on what happened when and (exactly) why I feel I tend to fall a bit short of the finish line.
I am familiar with the broader strokes of the story, how Celestion started using Fane patented glass fibre VCs in the late 1970 and mid ’80s went to Kapton, I believe, which came to be known as the first T75s: the White Labels. Shortly after the rear vents were omitted.
Then Marshall seems to have been displeased with the amount of cut from these drivers that they asked Celestion “how about using the K damper?” which leads us to the G12T75 we love to hate… or other. 😉
Now these may not be the more classic Celestion speakers and the story merely a bracket in speaker evolution, I so would have loved to get the story straight and void of too much guesswork. I do not expect you to deliver it on a silver platter, rather I wouldn’t mind doing some digging of my own – if only I knew where to dig. Any spot that picks your fancy? 😉
Kind regards.
Author
Hi Jonas, very interesting. That is all new to me to be honest. G12T-75’s have never been my thing really. Regarding “where to dig”, I can only recommend the usual places – obviously ask dr.decibel on the celestion website first port of call. Ask around on forums etc. Just be very careful who you listen to. There is a lot of nonsense that gets written, even from people who are supposedly experts and claim to have owned hundreds of speakers. The problem is Celestion rarely give out detailed information about their suppliers or specification changes like that, or perhaps they just dont know themselves anymore, so a lot of things you might read have just been passed down the grapevine so many times people think they are facts. Some classic examples are “all 1777 cones are Kurt Muellers”, “Celestion became Rola in 1970”. Some people still believe that stuff, it is ingrained in their brains. One of the main reasons I started this website was to put right a lot of these misconceptions flying around the web.
Probably the best way to learn in my opinion is to get your hands dirty. Buy lots of speakers, repair and dissect the faulty ones. Note any spec changes you see and hear. Stay inquisitive and just get stuck in. The things you learn from practical experience will often prove wrong the information you pick up from reading and asking around. That was certainly my experience anyway.
Hope that helps,
Brian.
Unfortunately what little I know about the G12-65 – G12T75 transition thing is what I have derived from various forums, however there seems to be this mindset that all T75s are identical and any difference in tone would have to be down to level of break-in or other argument to fit with their supposition, much like what you said.
I believe the VC former and damper stayed with the 75 through out the white label era but couldn’t say about the Power Speakers era. This era does seem to be a slim window just prior to the Professional Loudspeaker era, at which point the K parts would have had to be implemented.
If I was to buy speakers to find out once and for all that would likely be a Power Speaker one to more or less prove my thesis true. Unfortunately they are like hen’s teeth, particularly around these parts.

Say, Brian — The specs listed for “T5667 G10N-40 Ceramic 8 Ohm” speaker are wrong, compared to what you have for the “T5684 G10N-40 Ceramic 16 Ohm” version, which is “40w, 95dB, 98Hz, 1.75″ coil”, the same as Celestion’s page for the G10N-40 lists for both impedances (https://celestion.com/product/32/g10n40/). I hope you find this helpful. Cheers!

Hi Brian, missing data for T1102, G15C: spider frame (no front-mounting possible due to spider frame), 50 watts, Impedance: 15 Ohms, Bass resonance: 56 c/s (yes 56 not 55 as the 12′ Bass speakers have), Cone stamp: 02 751 002

Author
Hi Stefan, thankyou for the information. I have updated T1102. There are photos on google for verification.
Brian.
Hi, me again. Found a picture on the internet now with a Rola, T1480 which is the 8 Ohm version of G15 C. Bass resonance is indicated with 55 here. Not as my 15 Ohm 1968 model with 56 c/s. misprints ?
Author
Hi Stefan, thanks for the info. I have added T1480. It is likely Celestion made several different versions of the G15C with different T-numbers and slightly different in specification somehow. So there are probably more than just one 8 ohm version and one 16 ohm version of the G15C. They also changed the information on the labels through the years. The pre-rola vs Rola labels will often show slightly different information, even though the spec of the speaker is in theory the same. I do not have much knowledge or experience with the 15 inch Celestions but am happy to add them to the list for reference. Maybe someone else can clarify?
Hope that helps, Brian.

Brian, am looking at some graybacks with 1973 date codes, I know they were short lived between green and black, correct me if I am wrong, is it possible they have pulsonic cones!
Author
Hi Tom, yes it is possible they might have pulsonic cones, but it is not guaranteed. If I remember rightly the RIC cones start to appear around August 73, roughly the same time the grey magnet covers first appear. However there is some overlap with the different cone types they were using. I have had and seen plenty of greybacks with pulsonic cones. The RIC cones in late 73 might not have the RIC stamp on them. They can be blank or have yellow chalk markings on them instead. They are quite distinctive in appearance and sound though in my opinion and should be easy to identify.
Hope that helps,
Brian.
T6329B Redback 16ohm has 15635 cone.
T5891B Creamback 16ohm has
Celestion added “A” or “B” at the end of the T number.
Viewing all the speaker on Thomann I can see “A” is for China and “B” is for UK made speakers.
Probably to differentiate if production moves to a different country in the future.

Author
Hi Mark, thanks for the info. Can you email me some photos showing the cone code please, and I will add it to the list.

IL try in a moment
It’s typical early 80s dark stamp hard to get a picture of
It’s 2872 though
In fact other than the alu dust cap and the T number it matches another on your list so I’m assuming it’s a variation of the g12-125
It came out of a sharma cab similar to a Leslie from a local (Bournemouth) church organ if that information is of any use
I’m thinking it’s probably a 55hz fs at a wild guess
Author
Hi Mark, thanks for the info. I think this is likely a very similar speaker to model T2976, but with a silver cap and in 8 Ohm. The cone stamp on T2976 is ‘2877’ so yours are likely the same. I will add it to the list.

T1281 is on your list as being “most sought after greenbacks”.
Mine are BlackBack with gold Rola Celestion labels.
I found the same model on Reverb: https://reverb.com/item/24593788-celestion-vintage-t1281-g12h-30-blackback-speakers
Thanks. Jeff
Author
Hi Jeff, it depends when they were made. Your blackbacks are likely from 75 to 79. Celestion were always making changes to their speakers through the years. The magnet covers were green from about 1966 to 1973, grey from late 73 to early 74, cream from early 74 to early 75, black from early 75 to 79. They also used different cone suppliers through the years. These pages might help.

regards, Brian.
Thanks, Brian. Right, I saw your how-to-date vintage celestion greenbacks link that mentioned that T1281 greenbacks were highly sought after. Mine date to 1978 and seem to be valuable. Which is ironic because these T1281’s were in a Rivera 2×12 cabinet in 2005 I bought from a guy on Craigslist, instead of (new) Celestion 70/80’s or G12H’s. I was trusting, didn’t remove the back cover & they sounded good. I took the back cover off for recording later and saw they were older. I didn’t realize they’re vintage! Thanks again.

Hi. Thanks for compiling this list
I have two T2348 ten inch celestions.
They were originally in a Selmer SS30 combo
Date codes are LM18 (as best I can tell) so 1979
I can just make out 2348
The frames are black. The rear plastic covers are black/grey. Only one of the speakers had any stamps and they are only just legible being stamped in black ink on the black frame. There could be more to the markings or there could just be excess ink but impossible to read.
There are no cone markings and I believe they are original
There are stickers reading “Manufactured and designed to Selmer London specification” on the plastic back covers though I have no idea if they were a design exclusive to Selmer.
Thanks
Author
Hi Gregory, thanks for the info, I will update the table. These are basically a 10″ greenback style speaker as far as I know. I have seen examples of them before without the Selmer label, but it is possible they are a Selmer exclusive model. Usual cone stamp is ‘1129’. Should be great sounding speakers if they are working properly and still in good condition. regards, Brian.

Hi, thanks for the info. Updated thanks.

T1632 is kind of L magnet greenback. Mine has green (khaki) plastic back, no aticer, DE or DF date code (1972 or 73) and Pulsonic cone stamped “102 3”. It was imported by some polish amp manufacturer.
Author
Hi, thanks for the info. This one is already listed. The H1777 cone later “became” the 102 3 cone. Same spec cone, the ‘102 3’ is just a later stamp usually circa 72. regards, Brian.

Hi Dio, sorry for late reply. Can you confirm the T-number of the speaker is T3589 please?
thanks, Brian
Hi Brian – thankyou for the fantastic resource! I can confirm T2133 greybacks are 6ohm – just tested up at 5.4ohms with a meter. 1777 cone, 40hz bass resonance. Lucked out on a pair over the weekend on fb marketplace uk for very little money – they came in a couple of cabinets which somebody had put together to use as lineback monitors for their band at the time, thought to have originally started life in a 4×12 cabinet.. Hope thats of some use to you, J
Author
Hi Julian, yes it all helps, thanks for the info. I will update the list. 40Hz is low, how do they sound with guitar?
Brian.
No problem at all Brian – I unfortunately don’t own a guitar to try them with but rigged them up to my hi-fi to test and sounding pretty balanced across the frequency range with a nice strong mid. They are now up for sale on a well known site in the hope that they will end up being put to good use by somebody in a proper guitar cab.. Thanks again, J

Hello. I would appreciate some help:
I’ve just got two 70 anniversary G12H with a T4533B code and the data code is BG28.
It says “Made in UK” in the sticker but everything is very confusing since I cannot find what does the “B” mean and the date code is wrong too. It is clearly a “modern” speaker so it should have the number before the letters like “28BG” instead the “BG28”.
Am I dealing with a fake?
Thank you for your help in advance.
R.
Author
Hi Ricardo, sorry for the late reply. A BG28 date code would be 28th Feb 2021, and is in the correct MYDD format for the period. The letter ‘B’, or ‘A’, at the end of the T-number is not part of the model number and can be ignored. It is only for internal use at Celestion.
As far as I am aware there are no fakes of modern Celestion speakers around, so do not worry about that. People only need to be vigilant about the older speakers from the 1960’s – the ‘pre-rola’ speakers. A certain notorious vintage amp dealer in UK used to fake the model numbers, date codes and cone codes. Anything more recent is unlikely to be fake. More info on that on my page here: https://www.bygonetones.com/fake-vintage-celestion-pre-rola-greenbacks.html
Hope that helps, Brian.
Hi Brian,
Thank you very much for your reply. Don’t worry for the delay 😉
I have one more doubt I hope you can help me with:
My speaker says “Made In UK” in the white sticker of the side of the magnet, but I’ve seen other English models that says “Made in England” and “Celestion International LTD, IPSWICH, ENGLAND” in the back of the magnet like this one:
https://images.reverb.com/image/upload/s–n1Pf8ply–/a_exif,c_limit,e_unsharp_mask:80,f_auto,fl_progressive,g_south,h_620,q_90,w_620/v1491932392/p7aqsesooo0tfxvll4zt.jpg
Others don’t say “Made in England” but says “Celestion International LTD, IPSWICH, ENGLAND” like this one:
https://media.karousell.com/media/photos/products/2021/5/12/celestion_speakers_g12h_30_70t_1620838037_82df12c9_progressive.jpg
But mine doesn’t have the “Made in England” and says “”Celestion International LTD” without the “IPSWICH, ENGLAND”. Like this:
https://y6v8e8y4.rocketcdn.me/wp-content/uploads/2021/11/D_868335-MLA44023749662_112020-F.jpg
Can I trust my white sticker? Or it should need to be like any of the others to verify that is it really made in The UK? Are the others “more custom” or higher quality than mine?
Thank you very much!
Kind regards,
Ricardo
Author
Hi Ricardo, you might want to email dr.decibel at Celestion for clarification on that – drdecibel@celestion.com, but as far as I am aware if the T-number is the same, then in theory they should be made to the same specification whether made in UK, or elsewhere. It’s unlikely the quality is any different in my opinion. If it says “made in england” on the white sticker or the label on the back, then it is likely made in England. I would not go by the address printed on the bottom of the label. Hope that helps, Brian.
Thank you very much Brian! 🙂

Hi!
Just got a couple of old Celestion 15″ speakers inside (what I presume is) an early 70’s Roost cabinet Made in England from a friend. Couldn’t find this speaker in the list, so here you go:
G15/100, T2527, cone stamp 2233, 100W, 15 Ohm, Ceramic. Would very much appreciate some more info on those, but seems to be rare so can’t find almost anything on the Web.
Cheers!

Forgot to mention the date codes on these two: R (could as well be a K) -J13, and RJ14 respectively. Would be very happy if anyone could tell me how old these are?
Author
Hi Timmy, if you send me some photos info@bygonetones.com I’ll take a closer look, but if they are original to a 70’s Roost cabinet, then the codes are probably 13th and 14th Oct 1976. Letter ‘R’ does not compute as a month code, so they are probably ‘K’ for Oct. Or maybe the codes are back to front, I would have to see photos to confirm that.
regards, Brian.
Thank you Brian for your info, I highly appreciate it!
I’ll try to send you a few pictures of the speakers and the cab in question.

Hi Brian,
One similar model to be added. T5263 G12P-80 16 Ohm with 9855 printed on the cone: another Celestion Custom Design for Line 6 4×12 (red Line 6 logo on the back, pics available).
How to interpret the “50” and “10KN” also on the label?
BR, Chris
Author
Hi Chris, sorry for late reply, and thanks for the info, just added it to the list. The 10KN is the date code, likely 10th Oct 2003. I believe the ’50’ is just an inspection number or factory code, and is not relevant to us mere mortals, only the Celestion staff. Hope that helps, Brian.

Hi David, thanks for the info. Yes these are fairly common to find in all kinds of 70’s gear. Those magnets were also used to make the Jimmy Bean voice box believe it or not!

Brian – thank you for this compilation.
No surprises but 1) an additional number in the sequence and 2) an observation the same model number manufactured in England and China with different rear castngs …

{I replaced it with an Ipswich England, Century Vintage T5348 16 ohm}
Interestingly because I’m similarly in the process of acquiring a pair of Century Vintage for my VOX AD120VT I have found that:
T5348A were also manufactured in China HA 21 with a different fin layout (fewer and chunkier) on the rear Neo casting – but using the same model number …
Tim.
Author
Hi Tim, sorry for the late reply. Thanks for the info on the T5339, I have added it to the list. According to the new Celestion book the Neodymium magnets were re-designed “to attenuate the excessive treble that had plagued earlier designs”. The ‘fins’ are there to disperse heat. regards, Brian.
Hi Brian, I bought a cabinet with two mystery Celestions in it, and they’re not in this list. I hope it’s a useful contribution. I’ll email Celestion about it, as you suggested to other commenters.

Chassis: KM 3? (two characters legible, a third one faded, looks like a “3”. Suggests 1979, based on my research)
Chassis also has a “P” in a circle by the other codes, no idea what this means
No visible cone code
15 Ohm
Can’t find anything about this speaker, other than an archived classified ad saying “Dual Concentric Driver”, which corresponds to the speaker I have
Can provide pictures if necessary.
Kind regards,
IJsbrand

Hi, sorry for the late reply, and thanks for the info, I will add to the list. Let me know what you find out from Celestion and I will add it. Found some pics on Reverb.com

I got a 2018 VOX AC30S1 with the so-called VOX VX12 speaker in it. The white sticker on the magnet says G12P-80 16 Ohm T5729A. It is rated at 85 Watts. Which can only mean that the much discussed VX12 is not a relabelled Seventy 80.
Keep on rockin’ in the free world!

Hi Frank, the G12P-80 is the same speaker as the Seventy 80. Amp manufacturers sometimes like to put their own power ratings on there as Celestion’s own ratings can sometimes be on the conservative side. So Vox rate it at 85w, Celestion rate it at 80w. Hope that helps, Brian.

Hi, thanks for the info, I will add it to the list. regards, Brian.
Got a t6342a in a Vox AC15C1 from 2017. It’s a G12m ceramic 25w, 75hz, 16 ohm, with a silver magnet cover that’s branded “Exclusively for VOX”. I’m assuming this is the same a Chinese greenback from that time, and it is MIC.

Hi Daniel, I’m not familiar with that T-number sorry. If you email Celestion they should be able to tell you more about it. drdecibel@celestion.com. I would imagine it’s basically the same as a T1221 model though yes.
regards, Brian.
