I recommended experimenting with higher x-over frequencies because my experience with room issues has usually revealed the most audible problems lie between 50hz and 150hz, especially 80ish to 120ish . These are pretty common and usually very, very audible.
I use bass busters which are pretty effective at knocking out the hump between 80hz and 120hz in my current room. I cross at app. 75hz and the DRC in the SMS-1 does the rest. Without bassbusters, I'd start at 120hz to judge the effects of the DRC, then directly compare the sound to a much lower, audiophile approved x-over point. You may be surprised.
Note: if you use bass busters (or similar treatments), you can probably safely cross as low as 70hz - 80hz and get most of the benefit of DRC in the DD subwoofer. If you cross any lower, the DRC won't get a crack at the worst nasties in the room.
