The ACA Cyclone was designed in 1968 by Jim Biersach. The first version, the Cyclone 120, used a 40-horsepower motor and produced a sound output of 120 dB at a distance of 100 ft.

In 1980, the Cyclone was redesigned and renamed the Cyclone 125. It received a new rotor–stator assembly and a 50-horsepower motor, increasing the sound output to 125 dB at 100 feet.
