Or why not run it....

Mixer --> Sub --> Monitors (via the sub's hopefully high passed outputs)

I get that one might want to tweaking mains vs sub via the control room vs main output level controls, but in the real world it should be set and forget.

And running a single stereo signal from the mixer to the sub+mains combo means the ratio of sub output to the main levels is maintained at any mixer volume output level
