Type I field coil drivers’ magnetic circuits use a patented square wire coil
for 99.9% packing efficiency. This results in a more efficient, powerful, and cooler-running motor. The drivers perform with total effortlessness. The Type I motor’s yoke, pole piece and top plate are made of entirely of hydrogen annealed pure iron, in a design that achieves maximum saturation of the voice coil gap, for astonishingly good sonic performance — massive, beautifully detailed, supremely controlled and with seemingly limitless energy.
