A voltage biased capacitor circuit ( 10 ) for a loudspeaker ( 14 ') includes at least two audio circuit capacitors ( 32 A, 32 B) wired in series either on one of an audio connector or between audio connectors ( 16 A', 16 B'). A direct current voltage source ( 34 ) is wired in electrical communication with the audio circuit capacitors ( 32 A, 32 B) for transmitting through direct current voltage connectors ( 36 A, 36 B) a direct current to provide a bias voltage to the audio circuit capacitors ( 32 A, 32 B). At least one resistor ( 37 ) is secured between the audio circuit capacitors ( 32 A, 32 B) and the voltage source ( 34 ), to prevent dissipation of an audio signal through the resistor ( 37 ) and direct current voltage connectors ( 36 A, 36 B). A voltage source capacitor ( 40 ) is also wired between the voltage source ( 34 ) and the audio connectors ( 16 A' 16 B') to stabilize the direct current transmitted to the capacitors ( 32 A, 32 B).
