Using some very long balanced Subwoofer cables.

Thanks Al,
In addition, the 75 cables are; " the Monoprice Premier Series XLR Male to XLR Female - 75ft - Black - Gold Plated | 16AWG Copper Wire".

So, I'm thinking with 16 gauge wire there will be minimal signal loss.

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,
Thanks,
Only one 75 foot cable will be used on each master to slave unit.
I should have them soon to try.

Only one 75 foot cable will be used on each master to slave unit.

Understood.  But the 150 foot combined length of the two signal conductors in that one cable is what counts, in terms of resistance and loss of signal voltage.

Enjoy!  Best regards,

Oh, ok, gotcha.
