Subwoofer Position

Generally, subwoofers have the most output when placed in the corner of a room. However, this can also exaggerate the subwoofers output making blending with the main speakers difficult. If you choose to place the subwoofer in a corner near the front of the room it should be placed in such a way that there are 2 inches minimum between the woofers and the wall. Preferably, the subwoofer should be diagonal to the corner so each woofer is equidistant from the adjacent wall. This will avoid blocking the output of either woofer.

Before deciding on a permanent corner placement, experiment with other positions. Locations away from corners often prove more effective in providing ideal low-frequency performance and blend with the main speakers. If the subwoofer sounds like it has too much upper bass energy try pulling it away from the wall and toward the listening position (moving it out of the corner). This will lessen the wall and corner reinforcement of these prob- lematic frequencies and likely smooth out the response. Repeat the setup procedure with the subwoofer controls after moving to a new position.

Please note, some users may find that using PBK to take subwoofer response measurements will help optimize subwoofer placement. For more information please refer to the PBK section of this manual.

However, with experimentation locations away from corners often prove more effective in providing an ideal low-frequency performance and blend with the main speakers.
