how do you wire 2- 70volt volume controls to 1 speaker circuit so they can work independant?

generally, it is possible to wire the controls in parallel but use a 10 ohm isolator resistor on each wiper leg to prevent overloading of the line. this is not an ideal setup but i would need more details about the controls and your speaker setup to be more specific.
