Understanding 70v / 100v line Loudspeaker Tappings
https://cie-group.com/how-to-av/videos-and-blogs/tappings
100v line is the most common distributed sound system for commercial applications, particularly public address (voice) and background music systems where long distance transmission and large numbers of low level output loudspeakers are the common characteristics. 100v line has a more limited frequency range than low impedance audio, which is the reason for it's popularity …

A 100V line speaker is operated by applying 100V RMS from the amplifier to the speaker step down transformer via suitable figure 8 cabling. This stepdown transformer then converts the 100 Volts down to a standard speaker level to output audio.
70V / 100V Constant Voltage System - av-info.eu
https://av-info.eu/audio/70V.html
The term ‚100V system' or '70V system' relates to the maximum output voltage of the amplifier. 100V is the usual voltage in Europe, 70V in the United States. To generate this high voltage for the speaker line, the amplifier is equipped with a step-up transformer, which transforms the regular output voltage, in the 15 to 30 Volts range, up to the necessary 100V (or 70V respectively).

25V, 70V, & 100V Systems: Longer Speaker Lines or Smaller Gauge Speaker Lines: The reduced cable loss that results from higher amplifier voltages in constant voltage speaker systems, allows the designer the option to run speaker lines farther, or to use smaller gauge cable to reduce the cost of the speaker system installation.
Using and Installing 100v Line and Other PA Sound …

The reason for using 100v line on public address & PA sound systems is to minimise power losses in the cable. For example if a 30 watt, 8 ohm speaker is connected to a 30w amplifier by 100m of 6a cable (which over the 100m would have a resistance of about 4 ohms) a third of the power will be lost in heating up the cable because the power consumption is proportional to …
Audio Transformers - Learn About Electronics

In the 100V line speaker system, a transformer steps up the audio output signal voltage to 100V so that the output current for a given power is low. The resistance on long cables between the amplifier and loudspeakers will attenuate this low current signal much less than if the current were left at its normally high level.

Audio Transformer, its Types and Impedance Ratio

The step-up transformer increases the audio output signal voltage to 100V. Due to the Formula P (W) = V x A, when a voltage is increased the current decreases for a given power. The resistance would not effective for the low signal current. The signal will transmit perfectly.
