A cable assembly for connection between an audio amplifier and a loudspeaker in which a plurality of insulated electrical signal-conducting wires, or conductors are bundled together. The conductors are formed into two groups, one of which is connected between the positive terminals of the amplifier and the loudspeaker and the other of which is connected between the negative terminals of the amplifier and loudspeaker. The number of conductors and the diameter of each conductor is chosen and the design is such that the characteristic impedance of the cable assembly is within the range of the impedance of the loudspeaker. As a result a significant reduction in ringing and/or blurring of complex musical transient signals caused by reflections attributable to the mismatch between the characteristic impedance of the cable and the input impedance of the loudspeaker is achieved.
A cable assembly comprising a first group of conductors adapted for connection, as a group, between the positive terminal of an amplifier and the positive terminal of a loudspeaker;
A method of connecting an amplifier to a loudspeaker utilizing a multi-conductor cable assembly, said method comprising the steps of connecting the respective ends of a first group of said conductors between the positive terminal of said amplifier and the positive terminal of said loudspeaker, connecting the respective ends of a second group of said conductors between the negative terminal of said amplifier and the negative terminal of said loudspeaker, twisting each conductor of said first group of conductors relative to a corresponding conductor of said second group of conductors, and insulating at least a portion of each of said first group of conductors and said second group of conductors.
