Eminence Double-T 12: 12″ Pedal Steel Guitar Speaker
Rated at 300 watts, the Travis Toy Signature Double-T 12 pedal steel guitar speaker features a tight low end, a midrange bite that can cut through a mix, and detailed high end without being too bright. Travis worked closely with the engineers at Eminence to achieve these characteristics and even managed to pack them all into a 12 inch speaker that weighs just over 7 lbs – less than half the weight of the speakers he replaced.
