In general you want to set the subwoofer crossover to 1.5 octave above the -3db low point of the mains.

One subwoofer is generally not optimum, and can actually cause more problems in a room. Two subwoofers are usually better as they excite the bass peaks and dips less than one sub.
What is the rational of the last statement of using two subs rather then just one? Depends that also of phase and positioning of the sub or basically just because of the SPL potential?
