The speaker cable is used to make electrical connection between the loudspeakers and audio amplifiers. Like the other linear electrical component, the speaker cable has three components such as capacitance, resistance and inductance that determine its performance. There would have been no capacitance, no resistance and no inductance if the cable was perfect. The perfect speaker cable is short in length so that its resistance decreases as its length decreases in all the conductors. The resistance is the property which has the most effect on the performance of this type of cable whereas; the inductive and capacitive characteristics of this cable are considered small as compared to the loudspeaker. This type of cable is useful for home use only if its resistance is maintained less than 5% of the speaker’s impedance.  Read more...
