Hi Ozzy,
16 gauge is more than adequate. In fact even 24 gauge, which is sometimes used in XLR cables, would be fine (although I suppose the presumably greater physical fragility of the narrower gauge could conceivably be an issue in your application).
The input impedance of the balanced input of the slave subs is 10K. The combined resistance of the two 75 foot signal conductors in the 16 gauge cable will be 0.6 ohms, which will result in a loss of 0.6/(10,000 + 0.6) = 0.006% of the signal voltage. Which is a loss of about 0.0005 db :-)
Best regards,
-- Al
