Title: Rola Celestion G12Ms
Post by: LazyNinja on August 28, 2007, 03:22:47 PM
I happened to come into the possession of these speakers. Came with the cab I got as a part of a deal.

Does anyone know how much these are worth? I don't really need them so I'm thinking of selling them.

new greenbacks are worth around £50 each, check the age of yours to see if they are worth more

The serial number is a bit smudgy but it seems to say J122 AE25.

From your link it's probably 25th Jan 1972 :o

The ebay speakers are G12Hs and are slightly earlier (pre-rola) type with the 'Celestion' logo rather than the 'Rola-Celestion' logo.

If the cones are original and there is no rubbing on the voice coils I'd say the speakers are worth £300-400

Try playing with a spankin' clean tone on the neck pickup - there should be no 'grating' sounds on the speaker and the bass end should be punchy and true.

Have a look at the back of the cones through the holes in the frame and let me know what the lettering is on the cones.  You'll most likely see 003 or 3 but might also get 1777 - these are all lead cones and shows that the speakers have not been reconed.

Why do you want to sell them btw?

btw, that would be T1221 - it's the model number for THE classic G12M.

I don't have my Celestion dating info to hand, but '72 seems about right for those speakers - the green magnet cover, Rola-Celestion labels and black solder tabs.

Just got home and checked the serials of all speakers. You were right, what I thought it said was J122 was actually T1221 because the other ones were a bit clearer and they said T1221. Also it wasn't AE, it was AF, so that makes it '73 rather than '72.

Serial numbers:
T1221 AF25
T1221 AF25
T1221 AF26
T1221 AF26

I've taken one of them off the cab and it says "102 3"

They wrote or printed the '3' in quite a few different ways over the years, eventually ending up with just a single '3'.  Yours is indeed the famous lead cone these speakers are famous for.

Wowww sweet :twisted:

I'll probably hang on to them then. The cab seems shitee though, it's made of MDF and doesn't even have a center support pillar thing. Also it's furry :lol:

They're probably too vintage for you - I've got some G12T-75s here with your name on them  :wink:

get your self a nice empty 4x12 cab and do them speakers some justice.

the fluffy stuff is insulation to make it sound less boxy - might not actually be needed!!

:lol:

I played through it clean and it sounds very nice and rich but when there's distortion it starts to sound really buzzy :( Could be the cr@p cab but could it be the "grating sound" you were talking about??

Could be that the speakers are damaged too?

Or it could be that the cab is cr@p.

If the speakers are goosed, best way to test is a moderately loud clean tone with plenty of bass - twang the low E, palm-mute some notes on the low E.  It shouldn't be fuzzy at all.

The easiest way to rule out the cab itself vibrating is to take the speakers out of the cab and test them seperately.

if the fluffy padding is loft insulation its likely to be fibre glass which could in theory damage the speaker cones - get some gloves on and tear it out if it is
