3 SUBWOOFER SERIES PLACEMENT Placement Your DUAL subwoofer can be placed in many convenient locations in your home, but must be placed on the floor. Do not attempt an installation that would elevate the subwoofer above floor level. You should experiment with various place- ments. Room Acoustics can produce large apparent differ- ences in the sound for small changes in the placement location and adjustments to subwoofer controls. For Example, directing the woofer of a forward firing sub toward ones typical listening position and adjusting the low pass filter to 150 Hz can make the sub very directional. This means you perceive exactly where the sub is located within the room. This is not a desirable result for the most realistic audio experience. The common thinking regarding subwoofer placement and performance is to position and adjust the subwoofer in such a way that the subwoofers low frequencies encompasses the entire room with deep powerful bass and provides the most realistic imaging experience. The amount of bass per- ceived increases as you move the subwoofer closer to an intersecting wall surface and the highest level of bass results are realized from placement in a corner, but should be no closer than 3" from the wall surface. The floor and corner placement (loading) are actually an important part of the Subwoofers design. Attempt to place the subwoofer in or near the corner closest to your system's receiver to ensure the shortest possible wire or cable runs, which will result in superior performance. Indoor Placement
