Eminence Governor 12″ Speaker


Thick and raunchy with a powerful midrange, this is the driver for the classic British 60’s and 70’s rock tone

The Governor works equally well in closed and open back cabinets and combos, and is a natural match for the Black Jack Series. Connect one of these up to an EL64 tube amp, and the defining British rock tone is yours.


The Governor is a flexible all round driver that works well for lots of different applications, and is standard equipment for many high end amp makers.
