An amplified signal switching system comprises a plurality of transducers, and a switch operable for diverting amplified transient signals to selected transducers and preventing the amplified transient signals from being sent to non-selected transducers, wherein the amplified transient signals are AC or acoustic signals, wherein the plurality of transducers comprise a plurality of speakers, and wherein the plurality of transducers are isolated from one another. The switching system further comprises an amplifier operable for sending the amplified transient signals to the switch. The switch selectively turns the amplified transient signals on and off to the selected transducers in order to prevent the non-selected transducers from receiving the amplified transient signals. Moreover, the switch minimizes signal distortion in the selected transducers, and alternatively, the switch eliminates signal output to the non-selected transducers.
