In the united states if a 100v speaker system is installed in a commercial. In the us 707v is the highest voltage speaker system where class 2 wiring can be used without conduit.

100v line wiring diagram. The advantage of 100v systems are that the connections are simple to make without worrying about series and parallel circuits and impedances. The net result is a 100v line system allows for long strings of speakers to hang off a single amplifier output each speaker is connected to the next one in the circuit by daisy chaining the wiring. The wiring should be the same as the following diagram. As well as using volume controls it is also possible to switch loudspeakers so they are completely turned off a simple 2 way lighting switch could be used for this purpose. 100v settings are included because those speaker products are marketed outside of the united states. More importantly a mono configuration ensures optimal musicality regardless of listeners position in the room.
The above arrangement is typical of a horn or projection speaker which has a fixed tail cable grey above and requires a junction box to make the connection with the fixed wiring which runs from speaker. That said most 100v installations are done in mono as this makes the wiring a lot easier to do because you avoid wiring two separate lines. Connect many speakers to an amplifier. 100v speaker wiring diagram wiring diagram is a simplified usual pictorial representation of an electrical circuit. The way 100v line speakers are connected together is illustrated in the diagram below. Advantages of 100v line systems.
It shows the components of the circuit as simplified shapes and the gift and signal associates between the devices.
