The latter two factors also determine the wire's frequency response. The lower the impedance of the speaker, the greater a significance the speaker wire's resistance will have. Where large buildings have long runs of wire to interconnect speakers and amplifiers, a constant-voltage speaker system may be used to reduce losses in the wiring.
That means the capacitive reactance is about 80Kohms per foot at 20 KHz. So let's take a 20 foot (rather long) speaker cable. That means that the total capacitive reactance of the cable is about 4 KOhms. The output impedance of a transistorized amplifier is something less than an ohm, but let's take a hypothetical 16 Ohm tube amp instead.
Typical live use of a multicore (thick cable on stage) Multicores usually create a link between the stage and sound desk, or live room and control room.When used in sound reinforcement, the multicore cable runs from the stage box or microphone splitter to the front-of-house sound desk, where it connects to a mixing console.

While the above discussion focuses on preventing noise from getting in (e.g. into a microphone cable) the same star-quad quadrupole configuration is useful for audio speaker cable, [11] for split-phase electric power wiring, and even for open-wire star quad transmission line. In these cases, the purpose of the star quad configuration is reversed.
In electrical engineering, electrical length is a dimensionless parameter equal to the physical length of an electrical conductor such as a cable or wire, divided by the wavelength of alternating current at a given frequency traveling through the conductor. [1] [2] [3] In other words, it is the length of the conductor measured in wavelengths.
