It's the Black Shadows that are special. Mesa manufactures the baskets and sources the magnets, and then ships them to England to have the cones and voice coils installed. Mike has a Peavey cab (basically a Marshall clone) with the 85w speakers, and they sound very different from Black Shadows. Black Shadows are significantly darker.
