Abstract
In the case of power transmission cables, such as loudspeaker cables for connecting a loudspeaker to an amplifier, the problem occurs that on ensuring a high power transmission, it is simultaneously necessary to transmit information, e.g. also modulated musical information in an optimum undistorted and undisturbed manner from the amplifier to the loudspeaker. For solving this problem, it is proposed to construct one conductor of such a loudspeaker cable from an internal partial conductor and an external partial conductor surrounding the former and separated therefrom by a dielectric, said internal and external partial conductors being interconnected at the connecting elements.
