The table below is from the Belden website and shows how far you can go before you get to a specific loss. In this case, we show three values of loss: 11% (-0.5 dB), 21% (-1 dB) and 50% (-3 dB) for 4 and 8 ohm speaker impedance. But you'll notice a …
The Why and How of 70 Volt Audio Systems
http://erictraining.com/articles/AV/70-volt_cheat_sheet.pdf
The basic components of a 70-volt system are (1) an audio source, (2) a 70 volt amplifier, (Never hook up 70 volt speakers to a residential 8 ohm amplifier. Stuff could blow up!) (3) speaker wire (usually 16/2 gauge for runs up to 1,000 feet) and (4) speakers with transformers capable of receiving a 70 volt signal. Where would you use a 70-volt system?
25V, 70V, & 100V Constant Voltage Speaker Systems

level is 70.7V, so for all calculations, 70.7V will be used. 70.7V was chosen by the system designers simply to make the calculations easier. Typing 70.7 is cumbersome, so very often 70V is used as an abreviation. Keep in mind though, that 70.7V is the actual voltage value used. 25V, 70V, & 100V Systems:
Common Questions Regarding 70-Volt Audio - AtlasIED

Using Ohm's law, we can take the voltage squared (70 x 70) divided by the wattage (150) and get a resistance rating of 33.66-ohms. An impedance meter can be connected to the loudspeaker wiring at the amplifier to confirm it is wired correctly.

How To Design A Basic Commercial Sound System
http://erictraining.com/articles/AV/how_to_design%2070%20volt.pdf
Commercial sound systems are also referred to as 70-Volt Distributed Sound Systems. In a 70-Volt Distributed Sound System, a transformer is included with each speaker. This changes the system from low impedance (4 or 8 ohm) to high impedance and allows con-nection of a greater number of speakers in parallel to the amplifier. A commercial grade amplifier provides a higher …
