subwoofers at dawn

polytone reverberations or the appropriate dynamic frequency induce catastrophic vibrations in the cell walls of organic tissue;
resultant in the generation of self-contained microcavitation, and massive extralimbic transmission of celluar fluid

suffice to say, big speaker = big mess

concurrence is imminent

concurrence is critical - supraposition of concurrent waves is the principle on which polytone oscillators act in order to cause physical damage - three oscillators being independently tuned vis microcontroller until two of three waves are detected to be sufficiently within phase - their frequencies are locked and then the third oscillator tuned manually by an operator, carefully brought onto frequency and headphones applied before full power is directed to the voice coils.
