ABSTRACT:
A system for distributing a source voltage from a signal source to a number of drivers or loudspeakers is disclosed. The system includes at least one autotransformer for connection to the signal source, and a number of drivers electrically connected to the autotransformer. The autotransformers distribute the source voltage across each of the drivers. The autotransformers produce an output voltage across each of the drivers, such that the sum of the output voltages is substantially equal to the source voltage multiplied by the number of drivers.
