Interesting, I think I see that now, I thought the amp in the first sub would allow a balanced output even though the input from the 3808 is unbalanced. Still, if I understand correctly, the xlr input circuitry to the sub is set to a lower gain than the line (rca) input circuitry, no? Anyway the transformer for the xlr cable seems to be working to put the 2 subs in the same ballpark volumewise, so to speak. Otherwise they seemed too disparate in volume as a starting point to conveniently adjust the volumes toward a point of balance.
