The variable damping circuit includes an amplifier, at least one loudspeaker, a pair of connectors between the amplifier and the loudspeaker, and a reactive component wired in parallel with a resistor connected to one of the pair of connectors between the amplifier and loudspeaker, wherein the resistance value of the reactive component and resistor does not exceed fifty percent of a resistance value of the loudspeaker. The reactive component may be a coil, a capacitor, or both a coil and a capacitor both of which are connected in parallel with the resistor.
