From Celestion:

The Celestion G12-65 is regarded as one of the best speakers ever produced for use in a 4x12 cabinet. It was originally created in the late '70s using modern materials and techniques for a higher power handling

With its fast attack and tightly controlled low-end, the G12-65 had become a favorite with hard rock players by the early '80s. The precisely tuned mid-range and crisp defined top-end contribute to an aggressive crunch sound that punches through the mix while the mid-range warmth and detail give weight and depth to single notes.
