1. A panel loudspeaker controller for controlling a panel loudspeaker comprising a plurality of actuators attached to a panel, the panel loudspeaker controller comprising:

  • a plurality of electrical signal inputs, each input being associated with each actuator of the panel loudspeaker to be controlled;

    a plurality of signal processors, each signal processor being associated with each input and having an output for an electrical signal to control an actuator of the panel loudspeaker, and each signal processor implementing a transfer function from its input to its output based on each actuator of the panel loudspeaker to a desired acoustic receiver; and

    a signal processor controller associated with all of the plurality of signal processors, wherein the signal processor controller is preconfigured to improve phase alignment between the signals as an ensemble output at the outputs of the signal processors to reduce cancellation of a contribution to an acoustic output of the panel of one actuator by another.
