Do a search for "multisub". The idea is to use multiple subs to smooth room modes, making the bass sound good throughout the room. That's the best way to setup subs, but it does require more than one.
If you have only one sub, it will sound different at various places in the room. One thing you can do, if you are only interested in making it sound good at one spot, is to put the sub where your listening chair is and walk around the room listening (or measuring) to find the smoothest response. When you find it, put the sub there.
