1. A speaker system with acoustic event detection, the speaker system comprising:
a number of speakers;
a head unit including an output circuit structured to output an output signal to the speakers to cause the speakers to output an audible sound; and
an acoustic event detection module structured to receive signals from the speakers and to detect an acoustic event based on the signals received from the speakers,
wherein the head unit further includes a supervision circuit structured to provide electrical supervision to the speakers,
wherein the acoustic event detection module includes a processing unit structured to analyze the signals received from the speakers and to determine whether the signals indicate the acoustic event, and
wherein the acoustic event detection module includes one or more filters electrically connected between the supervision circuit and the processing unit and being structured to filter out the electrical supervision and to allow the signals received from the speakers to pass through.
