I would use both on opposite walls and then calibrate them at the same time. Both should have the same crossover, as it is usually done through your receiver and the subs' filter is on bypass. This should be a good starting point, this is what I plan to do when I get my next sub.

I am sure others with more dual + sub experience will be along shortly and have more to say.
