I modified the circuit so the volume control is on the low pass circuit. In my case each channel is attenuated 1db. Passive summing of two channels for single bass.

That seems to be the setup Charles Hansen recommends if you are using a sub, i.e., nothing intervening between the balanced preamp and amp connection and using single-ended for the sub.
