Dear Dr. Sound,

What is the maximum length of speaker wire for a 70 Volt line?

Thank you for contacting me. 
 

The maximum length of speaker wire for a 70V line depends on the gauge of wire being used.

Below you will find a chart with different gauges and their maximum length for use in a 70V system.
