1975 Celestion G12M Greenback Speakers T1221 75hz Pulsonic Cone 25 Watt RARE Original PAIR

A pair of 1975 Rola Celestion T1221 25 watt 16 ohm "black back" speakers, perfect working condition. Both have original late Pulsonic 75hz cones, codes 1777. The are the very last of the pulsonic cones with the very large ribbing and shadow around the dust cap. These are used 47 year old vintage speakers, but are in perfect working condition and sound AMAZING. The cones have some dust and a little staining, but have no holes, tears, rips and the voice coils are not rubbing. I did test these prior to listing with a guitar signal and a frequency sweep and they sound great. Perfectly as they should. Cosmetically they are also in excellent shape. Date codes stamped on leg are shown in photos. These speakers are extremely rare and are some of the most saught after Celestion speakers ever made. Don't miss out.

What are Pulsonic cones? The pulsonic cones first appear around mid 1962, most notably on the T530 “vox blue“. They are easily the most sought after cones by guitarists because they have a superior quality to their tone that cannot be found in any other speaker cone. Their slightly softer and more ‘fluid’ sound is particularly popular with blues and classic rock guitarists. These cones are highly collectible due to their association with all the legendary guitar players of the period such as Jimi Hendrix and The Beatles, and their use in the old 60’s Marshall and Vox amplifiers. Legend has it that the Pulsonic factory burnt down in late 1973 and with it went the magic formula for making those sweet sounding cones. Pulsonic cones appear on Celestion speakers until mid 1975. Even today nobody has successfully managed to replicate them, though several boutique brands have tried, as well as Celestion themselves with their Heritage greenback range.
