http://www.crutchfieldadvisor.com/ISEO-rgbtcspd/learningcenter/home/speakers_placement.htmlSubwoofer placementSince low bass frequencies are omni-directional, you can usually place your subwoofer just about anywhere in your home theater room, with good results. Just with other types of speakers, placing your subwoofer near a wall will generally result in more bass, and placement near a corner where three room boundaries come together will get you even more. Keep in mind that even though the bass increases as you place the sub near a wall or corner, the quality of bass may be slightly "boomier" and less controlled. Aim for a spot where you get a compromise between quality and quantity of bass. Consider these additional tips and suggestions for placing your subwoofer: One cool technique for placing for your subwoofer is to put your sub in your listening spot, play some music, move around the room, and listen. You'll probably notice that the bass sounds a little bit different as you move around from location to location within the room where it sounds the best is where you put your subwoofer. Many powered subwoofers are equipped with a phase control usually a 2-position switch. Choose the setting that produces the most bass while all your speakers are playing. For large home theater rooms, some people choose to use two separate powered subwoofers. Usually, the best approach for two-sub systems is to place one subwoofer in the front of the room, and one in the back particularly with 6.1-channel systems that include one or more back surround speakers.

8. Phase - For subs with a two-position switch for phase, or polarity, alternate between the 0 and 180 ; settings until you find the one that gives the most bass at the listening position. (If the 180 ; setting works best, repeat Steps 6 and 7.) If your sub has a phase knob, turn it until the bass suddenly becomes louder
Getting the subwoofer in phase can be a little tricky for a novice. The best way is to use a test tone at the crossover frequency of the subwoofer. Play this tone and adjust the phase so that the tone is the loudest at the listening position. Using an SPL meter can be a great help here. When it is at the loudest the subwoofer is in phase.
