CONSTANT VOLTAGE VS 8-OHM SPEAKER SYSTEMS

A constant voltage speaker system differs from a traditional 8-ohm speaker system in that
it uses a step-up transformer at the audio source to raise the voltage and lower the current
on the transmission line. At the speaker end, a step-down transformer converts the signal
back to a normal speaker level voltage. This reduces power loss during transmission, which
allows for the use of longer speaker wire runs using smaller gauge wire.
Additionally, a constant voltage speaker system allows for the use of multiple speakers on
each channel, without the need for complicated impedance calculations and
configurations. In a constant voltage system, all speakers on a given channel are connected
in parallel and the complicated impedance calculations are replaced by simple wattage
calculations.
