| Re: does this graph look right?
Since you aren't able to equalize the sub with the wiring configuration you've chosen, you might try to reduce the peak at ~80Hz by lowering the subs LPF a bit. You might also try the phase switch to help reduce that peak.
Other than that it looks fine. The sub has a spec of -3dB @38Hz, so you're more than beating that, and the transition to the mains looks pretty good except around 80Hz...
