than about 80Hz in order to avoid gaps in the overall system response, then you might well be able to localize
specific sounds from the sub. This can be very distracting when these sounds appear to come from beside or
behind you. One solution is to make sure the subwoofer is in the front of the listening area; another is to use
multiple subwoofers to make such sounds more diffuse.
Subwoofers also offer a phase control so the upper frequencies they produce will not cancel out the lower
frequencies of the satellites. A judicious tweaking of this control can pay major dividends in spectral smoothness
in the crossover area. Phase changes with frequency, however, so these controls may need readjusting every time
you vary the cutoff frequency.
Also adjustable is the overall level of the subwoofer's output. Many users tend to set this too high at first, in an
effort to achieve truly impressive bass. Again, smooth response is the aim, and it may well be that, if you use them,
two subwoofers end up being set differently—if, for example, one is in a corner and the other is not. It's all part
of the overall-balancing act that is bass management in real rooms.
We get virtually no inquiries about subwoofer placement from customers, which is a good indication that it's not
something over which people lose much sleep. A good subwoofer is such a pleasure when used with a good main
speaker that enjoyment is definitely the rule.
VI. Quick Start
Adjustable Rubber Leveler and Adjustable Spike Installation
Screw the supplied levelers or spikes into the threaded inserts located in the base, bottom or in the four feet
attached to the bottom of the subwoofer. Speaker spikes are for carpet use. Threaded rubber isolation levelers are
for shelf or hard floor use.
a) Carpet Use
Screw a spike with a lock nut attached into the insert located in the base, bottom or in each of the four
feet attached to the bottom of the subwoofer. Locate the subwoofer, adjust to the desired height
(higher for thicker carpet) by turning the spikes and tightening the lock nuts.
b) Hard Floor or Shelf Use
Screw a threaded rubber isolation bumper with a lock nut attached into the insert located in the base,
bottom or in each of the four feet attached to the bottom of the subwoofer. Locate the subwoofer,
adjust to the desired height by turning the rubber isolation bumpers and tightening the lock nuts.
If you cannot wait to hear your new PSB subwoofer: Turn off all other components, and follow one of the
connection diagrams. Connect the supplied power cord to the AC power socket. Set the PSB subwoofer volume
control to its minimum position (counterclockwise), then plug the subwoofer into an active AC outlet. The same
receptacle as the rest of your audio/video system or another on the same electrical circuit should be used to avoid
ground hum. Set the subwoofer's Sub Cut-Off Frequency control to its midpoint, and the phase switch to 0°. Flip
the Power Switch to the on position. Play a bass-rich program source, and slowly bring up the Sub Volume control
(clockwise) until the subwoofer contributes a natural level of low frequency sound. Now please read the rest of
this guide and fine-tune your installation accordingly—it will be time well spent!
