First and foremost it is important to us that a PSB subwoofer be musi- cal. In this era of home theater this might at first seem out of step, but we believe that a musical subwoofer will also sound the most natural when playing movie soundtracks.

We suggest you save the original carton and packing materials, at least for an ini- tial period. Should you ever need to ship or store your PSB subwoofer, it is the best packaging in which to do so.

ROOM ACOUSTICS, SUBWOOFER PLACEMENT, MULTIPLE SUBWOOFERS & CONTROL SETTINGS Room Acoustics If you are critical about low-frequency response, there’s quite a bit of useful experimentation you can do, especially in combination with the crossover, level, and phase controls of our subwoofers.

Things are more controllable through the use of a subwoofer or two. Positioning of the bass speakers has almost no impact on imaging, so a subwoofer can be located with only standing waves in mind.

Bear in mind that the test only works if you have your ears as high off the floor as the subwoofer will be, so don’t be afraid to crawl around. A recommended starting point for the placement of this subwoofer would be in either of the front corners of the room (on either side of the main speakers).

Figure 6 (the two subs do not need to be identical). Please refer to Section V, Multiple Subwoofers for further information. VII. SET-UP CALIBRATION The following procedure assumes your PSB subwoofer is installed and connect- ed. If possible, work in a team with another person: one listening, one making subwoofer-control adjustments.

B. Play a familiar compact disc, LP, or video soundtrack that includes substan- tial deep-bass content over an extended section. Your PSB dealer can help you select a few such titles. C. Gradually turn the Sub Volume control clockwise until you achieve natural balance between the subwoofers deep-bass output and your main left and right loudspeakers.
