Introduction:

Speaker Levels: (loudspeaker loads)

Low Impedance System - 4Ω and 8Ω

High Impedance System - 70.7 V

The cable is used to drive loudspeaker loads that are normally between 2 and 32Ω, although most systems are 4 and 8Ω. If the 

concern is to deliver amplifier power to the loudspeaker, as the case for most commercial sound applications, the design procedure 

is straightforward, with cable resistance being the only concern. If the highest audio fidelity is needed, the cable construction will 

become an issue.

The resistance of the cable is the most important electrical issue in loudspeaker installations. The effects of capacitance and 

inductance are negligible.

Low Impedance Systems: output impedance is low, the current must be high in order to get a given 

amount of power to the speaker. The lower the resistance of the cable, the more power gets to the speaker. 

High Impedance- Distributed Loudspeaker System- Constant Voltage System: Impedance of 4 and 8Ω are most common in amplifier 

outputs. Manufacturers of commercial amps might also supply an output transformer with a number of secondary's, one may be 

marked 8Ω and the other marked 70.7 V. The impedance of a 70 V output transformer depends upon the wattage of the amp. 

A 25-watt, 70 V amp has an output impedance of 196Ω.

Actual speakers are still 4 or 8Ω, however, so when the wire is connected to each speaker, there must first be a small transformer to 

reconvert from 70-volt to 4 or 8Ω. The quality of the transformer is critical. Distributed systems are used where quality is not the 

primary consideration, such as, public address, background music, 

or paging systems.

•High impedance loudspeaker distribution systems being higher voltage and lower current

  than low impedance (4/8Ω) loudspeaker systems have the following features:

• higher operating voltage means less power is consumed by copper resistance

• longer lines can be run before wire resistance becomes a concern

• lower operating current means that thinner wire can be used

* 70-volt line drive systems, while considered a potential for Hi-Fi performance, 

follow the same cable loss physics as the higher current (lower Impedance) system. 

For sake of this calculation, a 25 watt 70-volt system (196 ohms) was used.
