Greenback's, chaque HP's encaisse 20W ou 25W (suivant l'année). Les premiers encaissaient 20W.

Extrait de mes nombreux échanges avec Celestion sur le sujet :
//////////
The T1221 was originally a 20W speaker but I think by this time in 1968 they were called 25W speakers.
There were no actual changes made to the speaker other than the number on the back. I guess someone did more power testing and realised the speaker could be called at 25W. This would also make it look better in a 4x12 cabinet with a 100W amp.
