Big question, and one I'm dealing with right now. My peak is about 32 Hz, with a double at about 64 Hz. (Might be a 16 fundamental, but the test doesn't go that low.) We've got standing waves in our room. In other words, the rooms have natural resonant frequencies that are excited by the subs. That means that there are nodes and nulls in the room, too: spots with lots of signal and spots with very little.
There are two approaches that I know of to deal with it. 1) equalization, that massages the signal to chop down the peaks. Unfortunately, I don't think EQ can do much for nulls without overdriving the sub. 2) Room treatments to absorb the resonance. These are tough to apply if you don't have a dedicated HT room.
People that know a lot more about this than I hang out in the Audio Theory section. Best take it there.
