User's Manual 10 Your Sunfire Subwoofer is designed to be placed in a corner and this will produce optimum performance. Experiment with at least two corners and then decide which is the best. #1 is very good positioning. #2 is also excellent but may shake the back wall too much and cause things on or along the wall to rattle too much.
