A rather unique and rare speaker cabinet intended for professional use by guitarists. Fitted with a single 12" speaker and eight 8" speakers with magnets of varying flux. Maximum output of this combination was stated to be 100watts, and it seems to have been intended for use particularly with the Dominator 50 amplifier head.
Watkins also used the name Aggressor later during the 1980s for a totally different pair of PA speaker cabinets.
