PLACEMENT AND FINE TUNING
The placement of your new subwoofer is critical to its
performance. The three most common locations include:
A) In the corner of the room (which can result in a boomy or
exaggerated low frequency response), B) Placement along
one wall but out of the corner (moderate bass performance
with increased fidelity over corner placement), or C) Alongside
a front speaker (creating a better blend with the front speaker,
but sacrificing overall volume). Experimentation with subwoofer
placement is highly encouraged, as slight adjustments can
create large benefits in sound reproduction. To further test
subwoofer placement, place the subwoofer temporarily in
your main listening chair and while playing a familiar piece
of music, crawl around the listening room until you find the
best-sounding position. This is usually a place where the
subwoofer will perform well, and possibly at its best.

FINAL SYSTEM ADJUSTMENTS
1. After you have made all connections, but before making final
adjustments, we recommend you let your new subwoofer
play with an action movie or pop music for a few hours to
let it break in.
2. Select the correct position for the POWER switch, either ON
or AUTO depending on your system. The AUTO selection
will leave the unit in a self-sensing mode, such that should
the unit sense an audio signal it will turn itself on and then
shut down after several minutes without signal, while in the
ON position the subwoofer always remains on.
3. Adjust the LEVEL control so that the volume of your subwoofer
matches the overall system volume. This ensures a smooth
transition between the low and high frequencies of your
system. If the subwoofer is connected to an A/V receiver
or surround processor, you will need to set this control so
it gives you enough range to fine-tune the level using the
channel level adjustments in the receiver or processor.
4. Adjust the LOWPASS (HZ) control so that the frequency
range of the subwoofer blends well with that of the front
speakers. If you are using an A/V receiver or surround
processor, we recommend you set this control to 150 Hz
so the receiver or processor can perform the subwoofer
crossover functions. If you are feeding the subwoofer from
a stereo preamp or receiver, when using small satellite
speakers, the appropriate crossover frequency should be
from 90 Hz to 150 Hz, for bookshelf speakers 70 Hz to
90 Hz and for large floorstanding speakers 40 Hz to 70 Hz.
Setting the crossover too low will create a gap between
the frequency response of the front speakers and that of
the subwoofer, while setting the crossover frequency too
high will create a doubling of certain frequencies, making
the music sound boomy.
5. Adjust the PHASE so that the subwoofer integrates fully with
the rest of your audio system. This control ensures that the
subwoofer operates in phase with the rest of the system, as
an out-of-phase subwoofer will either sound like it is lacking
in bass performance or that its timing is off. This setting will be
determined by your listening position, the characteristics of
your listening room and its interaction with your subwoofer.
We recommend you start with the control set to 0, then listen
to music with a melodic bass line. Now set the control to 180.
Whichever setting delivers the most tuneful and consistent
bass output is usually the best one. Experiment with the
in-between settings on the PHASE knob if you wish.
6. Steps 2, 3 and 4 might require repeating in order to fine tune
your system. Ensuring the proper blending between the
speakers and the subwoofer is critical to the performance
of your system, as a whole.
