Is there a better way of tapering the cable ends, instead of using a thinner cable?
The speaker cable resistance is derived from the specific resistance of the conductive material (copper wire) and the length of the cable. Because a speaker is connected to the amplifier via two cable connections, which are connected in series, resistance 2x must be taken into consideration. This results in the following equation: Resistance of cable = 2x the specific resistance (approx. 0.02 Ohm mm^2 m^-1) x cable length in m / cable width in mm^2 The individual wires in our cables are not insulated from each other, so the full cross-section of the cable is available between the ends. This means that the “bottleneck effect” only happens at the ends of the cable. The transition between the cable and any connector (push terminal, solder connection or terminal post) is always accompanied by a large resistance, contact resistance. “This can be ignored with good versions, when compared with the resistance of the cable as a whole.” Example: Let’s consider a cable length of 15m.
