Originally created as a higher-power handling variant of the G12M Greenback, the G12-65 is widely regarded as one of the best speakers ever produced for use in a 4x12 cabinet.
With its fast attack and tightly controlled low-end, the G12-65 became a firm favourite in the ʼ80s with hard rock players. The precisely tuned midrange 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.

Long excursion 12" woofer with 800W power handling for
subwoofer application. A special 3" copper voice coil using
proprietary high temperature adhesives and an optimized
magnet assembly guarantees superb LF dynamic range with a
very low distortion. Due to the linear characteristics of the 12
PZ 32, exceptional results are obtained in horn loaded
subwoofer applications.
