If you have a smaller room, there may just be one place that your subwoofer sounds good and can fit. For instance, putting the subs in the front corners will excite the same room modes but from opposite points in the room, exactly 180 degrees out of phase with one another. good luck! Being out of phase in this way will cancel out the modal resonances, which can be hugely beneficial when creating a flat response within the subwoofers’ operating range. In a bit of a rut. With properly located dual subwoofers, the respective modal patterns will overlap, which greatly increases the sound wave density in the room. Place one sub at the 1/4 point and the second sub at the 3/4 point of the front wall (or the rear wall).
