Dating celestion g12m
This will be a general guide because even within each speaker type listed, there are various changes that have been made throughout its life.For example, a late ‘60s Celestion 25 watt G12M will sound different from one made in 1979 because the ingredients used in the creation of the speaker changed over time.It emphasizes the top end crunch of a distorted rock guitar, but rolls off many of the most extreme highs that more efficient speakers can reproduce.
The end result is that it is a quieter speaker (at the same comparative output setting on an amp) than others including the G12H or Vintage 30.A few d Bs in reduced sound output makes quite a difference!The G12M-25 watt from the late ‘60s through the early ‘70s are my favorite Celestion speakers for classic hard rock and blues tones, and the Heritage series 20 watt G12M reissue is also a fantastic speaker choice for this genre.Throughout the1970’s, the color of the magnet cover was changed (beige, black, etc.), but the basic ingredients, other than a few variances in the cone, largely remained the same, until the late ‘70s, circa ’78-’79, when new materials in the cone diaphragm were explored.
The tone of the G12M is the foundation for much of the greatest rock and blues music ever recorded. And what does one sound like "in real life" away from the world of recording studios that can alter, shape and compress the sound through the mixing board, e.q., and other processors?There are also a plethora of other topic areas that we could cover in the future that go into depth about calculation of speaker and cabinet design, magnet types, cones, and how they each impact tone.
