place any subwoofer or subwoofers where they sound best as a first effort. consult the owners manual. making a nice "stereo pair" looks nice and tidy but you may be wasting their potential. usually subwoofers are recommended to be placed near corners for best response without getting too close to the walls to cause peaks in the response.
behind the listening area is certainly acceptable as long as you refine the position by testing. too close to walls you will hear an exaggerated peak (one note louder than the others, not good)
pick your spot and then listen to see how it sounds. too weak = too far from wall boundaries, too over powering, too close. usually 12 inch from walls minimum.
