Placement and Positioning

The goal of proper placement is to achieve a smooth, extended bass response. We strongly recommend that you experiment with placement before choosing a final location for your subwoofer.

Place next to a wall to increase the amount of deep bass.
Placing in a corner (1) delivers more deep bass.
Note: Placing in a corner (1) also activates room modes which can make the bass response less smooth.
Placing the subwoofer along the same plane as the left and right speakers (2) produces the best acoustic integration with the main speakers.
Placing the subwoofer close to the listening position (3) helps remove poor bass response caused by room variations.

The best way to determine the location for the subwoofer is by temporarily placing it in the listening position and playing music with strong bass and midbass content. Then listen while moving around to the various available positions for the subwoofer in the room. Putting your ears where the subwoofer would be placed is best. The best subwoofer location is the one where you perceive the best bass performance and midbass blend, due to acoustic reciprocity. Place the subwoofer in that location.
After finding the location that works best, adjust the Crossover, Volume, and Polarity to fine tune the output of the subwoofer even further.
