And thanks, DanceMan, I will most definitely keep that in mind if I have trouble once I set the system up.

In simpler terms, start with the sub where it's convenient, and move it away or toward the corner, and away from or closer to the wall, or elevate it off the floor until you eliminate the boominess from the room resonances.

The math part is simple. Working from the resonant frequencies, the positioning from reflective surfaces will likely create or increase peaks when you have exact fractions of those frequencies. Ironically, a computer program would probably be the best way of doing the calculations.

A theoretically perfect speaker radiating in an anechoic chamber (no reflections, 100% absorption) could have a flat frequency response. As soon as you put it in a real room, the frequency response will have peaks and dips from reflected waves adding together and cancelling. When the room dimensions match certain frequencies, those will be enhanced. When the distance from the source to a reflecting surface is an exact fraction of a given frequency, the adding and cancelling gets worse. Think of the wave tanks in elementary physics to get a visual idea of it.
