May I at least ass-u-me that you plan to high pass these horns? If so, go ahead and figure that in, too. In any case, just looking at 70', impedance is not the only number you'll be running up, and the last place you want this load is for LF chan...

Ideally, you'd want to drive 35 feet of balanced interconnect with the low impedance source ( say below 150 ohms or so). How low depends upon interconnect capacitance. You can try Jensen output transformer to convert SE to Balanced at the phono-stage...
