These first speakers went through quite a few changes (also appearing in different colours like silver, chrome and red – also with different codes) during the early years, but they remained with a low (in today’s standards) 15w (20w in latter versions) power handling and with both 8ohms and 15ohms options. With the 100db sensitivity, it was a very “loud” speaker.
So, I’ll emphasis again the fact that it’s not the power handling (watts) that will determine if a speaker is “louder”, but the efficiency (db).
The power handling will only tell how much wattage it can take safely without blowing.
The G12M speakers were mostly found in the old Marshall 1960A and 1960B cabs.
1969 Marshall 1960A cab with G12M 25w 75hz The 55hz version was used in the 1935A and 1935B cabs (same measures as a 1960 cab – they usually came with a “Bass” logo on the upper corner until the early 70s).
During the late 60s, they had a “100” logo on the upper corner, indicating that the cab was loaded with the heavy-duty 25w speakers (remember that early G12M had only 20w and the G12H speakers had 25w instead – thus making the 1982 the first 100w cab).
Just before the 70s, the “100” logo was dropped (the cab was now rated at 120w, since the G12H was powered up to 30w sometime around April 1968 – you can still find the “100” logo on cabs made up to 1969) and so, since they also had the same measures as the 1960 model cabs, it’s almost impossible to tell them apart without further inspection (just like the 1935 cabs).
Speakers are extremely important when we are talking about tone. This article will be a (maybe not so) small post about the history of Celestion, as well as a brief description of each model they produced over the years. I’ll simply feature the ones that I think are the most popular and most widely used models. Early years and the G12 Al Ni Co Celestion started as a manufacturer of speakers for general use (radio, TV, etc.) back in the 1920s.
They give the amp its “voice” and so, in order to get the right sound, you will need to use the right speaker. In 1947, it was bought by British Rola and, one year later, production moved to Thames Ditton.
1970 Marshall 1935A cab with G12M 25w 55hz and the “Bass” logo G12H An early G12H 25w Note how bigger the magnet is when compared to the G12M The G12H (heavy 50oz ceramic magnet) was introduced as a heavy-duty speaker to handle more powerful amps (in a similar way to the G12M, the G12H’s first versions handled only 25w and then they were powered up to 30w in 1968 – Yeah.Tags: Adult Dating, affair dating, sex dating
