ABSTRACT:
A four-way electrostatic speaker system includes four step-up transformers which have their primary windings connected in a series-parallel circuit across an audio signal source. Electrostatic drivers connect to the secondary windings of each step-up transformer and each forms a parallel resonant circuit which is tuned to an audio frequency within the operating range of the electrostatic driver. The impedance reflected into the primary winding of each step-up transformer is such that the attached electrostatic driver predominantly receives frequencies within its operating range. The necessity of a separate crossover network is thus eliminated.
