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.
For example, if you want to connect two speakers per channel in a traditional 8-ohm
speaker system, you must either connect them in series, which results in an overall 16-
ohm impedance, or in parallel, which results in an overall 4-ohm impedance. In the first
case, the 16-ohms impedance effectively halves the output power of your amplifier,
