Hmmm, I'm guessing since you said you got a "pair" of speakers, the last post wasn't really helpful. A couple of rules of thumb, since the devil is in details you didn't post:
- Make sure the speakers are an equal distance from your listening position; otherwise you throw off the soundstage image.
- The closer they are to a wall, the boomier the bass will be; if you put them a couple of feet out you'll have much tighter bass
Good luck,
