I compare the two most influential vintage Celestion speakers. The Alnico speakers were used in the Vox cabs and combos and in the very earliest Marshall cabs and combos. The Greenbacks were used in Marshall cabs and combos from the mid 1960s until 1973. The two speakers I'm comparing is a 1967 Celestion T1088 Alnico (which is the model as T530 Blue, but this one is sprayed Silver) and a 1972 Celestion T1221 Greenback (G12M25 75Hz). Both are original and feature Pulsnic cones. So here we're comparing Alnico vs ceramic magnet.

I'm using a 1975 Gibson Flying V and a Pure Tone Amps Offset to compare them. The speakers are put in the same 1980s Marshall 1x12 model nr 1933. The close mic is a anodyne IV 548 and the room mic is a Beyerdynamic M160.
