Abstract
A speaker system includes one or more rotating speakers (or speakers with rotating reflectors) that are synchronized in absolute angular position to another rotating speaker or synchronized to audio effects to generated by a signal processing system driving a stationary or rotary speaker. Knowledge of absolute angular position in a multi-rotor speaker array or signal processing system allows for control of rotary position to accomplish acoustic effects otherwise not possible, such as matched-velocity profiles with differential phase control and motion profiles that are not based on simple rotation.
