About Room Placement
Room placement is the first step in equalizing your subwoofer(s) to your main speakers and your
r
oom. Subwoofers operate at extremely low frequencies, which are primarily omni
(that is, you can’t usually tell where they are coming from). Placing the subwoofer(s) in the
room is a trial and
best location(s) that result in the minimum number and severity of valleys in the frequency
response curve. This is because peaks in the response curve are easy to address with an EQ,
but valleys typically are not easily fixed because they represent a cancellation of frequencies that
more power to that frequency will usually not fix.
As a general rule, placing the sub(s) in the corner(s) of a room will add to the overall amount
of bass the subwoofer produces, but that bass may not necessarily be as low in distortion
compared to a position away from the corner. The worst location for a subwoofer is typically
far away from any walls, and close to the center of your room. Avoid these locations when
possible. When using a pair of subwoofers in stereo, it is preferable to place each subwoofer
by the satellite of the same channel. If moving your satellites is an option, they too can
contribute to peaks and valleys and should be likewise placed through experimentation.
Now you can begin moving your subwoofer(s) around the room to find the best placement
position. You need to find the best tradeoff between appearance and room response. Be sure
the room is in the configuration that it will be in when you typically listen

IP: Here’s an easy way to find the optimal position for your subwoofer without moving it to
multiple positions in the room. Start by setting the subwoofer up in your listening position.
N
ow, move the microphone around the room and observe the response graphs for different
room positions. The best position has the fewest valleys and the overall smoothest response.
NOTE: If you are constrained in room location positions, don’t worry! By following the setup
steps below, Digital Drive bass management gives you lots of flexibility to make the most out of
any subwoofer placement position.

and change values using the SET +/- buttons.
14. When setting the low pass crossover, begin by setting the frequency and slope to the same
values as the crossover settings on your receiver/processor (for example, many units have
a large/small satellite setting). Again, consult your receiver/processor owner’s manual for
more information. You will notice that changing these values “cascades” the values out to
all the presets. That is because once these values are set, they will not normally change
from preset to preset, but if later you wish to customize a specific preset you can. An
example of a crossover changed to 100 Hz is shown below:

6. You should normally not need to adjust the subsonic filter. Do so only if there are anomalies
in the very lowest frequencies that you cannot address using the normal EQ process as
d
escribed below.
17. Next adjust the phase and polarity settings. Phase is in effect a short delay in the
reproduction of the audio signal. The polarity reverses the phase (i.e. 180oshift).
Adjusting phase can change the dynamics of standing waves and frequency cancellations
in the room. Sometimes it may be useful to adjust the phase if there is a particularly
difficult peak or valley to eliminate, and/or your room placement options are limited. Phase
and polarity are also important tools to match your subwoofer to your main speakers. You
will often see a dip or peak in the crossover frequency between your subwoofer and main
speakers. Rather than correcting this dip with an EQ, try adjusting the phase and polarity
settings. It is very common for the main speakers to interact with the subwoofer to
diminish or accent frequencies near the crossover point (since this is the point where both
the subwoofer and the speakers are playing the same audio information). Don’t be afraid
to experiment to find the perfect match between your subwoofer and main speakers!

About Room Equalization
T
his section gives some background on room equalization. As a subwoofer plays in a room, the
reflections of the sound waves off the walls create “standing waves,” that is, places in the room
where certain frequencies are louder and others are diminished. In addition to standing waves,
every room will also have locations where cancellations of the sound waves are like black holes
that no amount of attenuation can fill. Thus as a general rule it is better to “cut down” a peak of
response rather than to “boost up” a valley (i.e. possible black hole) of response.
In general, you are looking for a frequency response that is +/
doubtful that your ears can tell a response that is any better than this). The response will always
roll off at the low end (according to the settings of the subsonic filter), and there should be no dip
or peak at the crossover frequency with the satellites. While the goal is perfectly flat response,
this may not be possible in the higher frequencies of the subwoofer’s response due to peaks or
valleys introduced by the satellites.
