Celestion G12-80 Rola

I have a marshall 4 x 12 with four Celestion G12-80 Rola speakers in which I got a few years ago not knowing anything about speakers. Does anyone know if they are any good or how much they are worth? There seems to be differing opinions on them everywhere I look.

What is the T number? There are many different types of g12-80 and some are not designed for guitar.

Could you elaborate on T number?

The code on the frame beginning with the letter T  is the model number of the speaker and tells us the specification.



If you can't find it on the frame it might be stamped on the label itself.

eg T3103 is a bass speaker with the 444 stamped cone.

Here is a list I cobbled together that might help you:

I'm not sure what distinction is between wow and wisdom but I upvoted you on both!

If you want to be convinced of the quality of your existing Rolas just take a look at this ep of the Doug and Pat show  where their beloved VOX AC10 head is being thoroughly discussed. Is a speaker swap in the cab at the end... The Rolas win it by far.
