Welcome.
From the entire SVS team, congratulations on your purchase of a
new standard in home theater and music bass!
Your sub isn’t some generic black box built someplace you can’t even
find on a map. It’s made in our Ohio, USA factory by home audio
fanatics... like you. Designed, and tested using the latest state of the
art instruments... and assembled by hand, your SVS subwoofer is
without a doubt one of the best investments you’ll ever make in bringing music and theater home.
We’ll help you to set up your sub right, and in no time, you’ll be giving “demos” of your favorite DVDs or music selections to all your
friends and neighbors (be kind if you live in an apartment). This isn’t
just a “subwoofer” after all, it’s a carefully designed audio component
carefully tuned in our labs, by the award-winning SVS design team.
You’re unlikely to have heard, or felt, bass like this before, unless it
was in a top-notch, commercial movie theater. Audio i n your home
will never be quite the same again. That’s a promise.
Already have a question about your sub? You might answer it by
reading this manual, we think you’ll find it easy to read and more
informative than most. For even more detailed discussion about setup topics check out our Questions/FAQs page at www.sound.com.
We touch on a l l the key points you need to know, and then some.

About your SVS Subwoofer
There maybe be other subwoofers that look like them, but virtually none
work like them. Not at this price. SVS subwoofers are decidedly different i n how they
are designed, produced, sold, and even in the exceptionally high quality components
we use. The best part? You could have spent much more and still not come close to
the performance our subwoofers provide. So, what makes a subwoofer an SVS?
Quality components, sane prices. You might be surprised at how inexpensive
the components are in some not-so-inexpensive subwoofers. At SVS, performance is
king... not shaving off a few dollars from component costs to improve profits. We
scour the earth for the most cost-effective parts (when we don’t make them ourselves),
and meld them into finely tuned designs that define high performance movie and
music bass. We’ve tested and discarded plenty of bits that didn’t meet our tough
standards. If we use it, you know “it” is satisfied some tough customers first. Us.
Get “square”. We did a host of studies to optimize materials, the size, and even the
our enclosure finishes to ensure a rigid design that’s reasonably compact, and still able
to take the abuse your family and friends can dish out. SVS cabinets are no ordinary
boxes. Selling through select dealers means your sub, and not glossy ads, get the
priority at when your product is built. Tap the side of your sub, look at those smooth
corners, flip a few switches. The quality is so obvious, you’ll know what we mean.
SVS products are different.
Stable downward firing woofer. Our contemporary enclosure designs are a halmark,
but we’ve also taken great lengths to allow for top quality, well-protected woofers.
Coupled with our unique base-plates, which minimize driver reactive forces, you’ll
find our down firing subs can take a tremendous amount of power and remain rock
solid. Compliant rubber feet allo w for st able placement on a variety of surfaces. No
rattling, or buzzing allowed!
Custom low turbulence port designs. When you listen to our trend-setting
ported subs you’ll hear (and feel) bass like never before, with a exceptionally low
noise and distortion. Huge patented, flared port fittings make the difference. You’ll
quickly realize something special went into your new sub the second you fire it up.
Stylish, and understated. From the fine, durable finish, to the attractive color-
contrasting components, you’ll be amazed at how easy it is to lose your sub in a
corner. SVS’s aren’t tiny, but this is one of those times size does matter. There are
many brands of boring “black box” subs. Fortunately, you didn’t just unpack one.
World class power. Our Canadian-built amps are designed and manufactured with
a level of quality and power practically unheard of at this price. Did we mention
power? It’s there in spades (though we rate them conservatively). And SVS starts
with efficient designs which don’t require significant levels of power robbing
equalization to go low and flat. This way, our amps can be dedicated to reproducing
low frequencies, not making up for a lack o f enclosure space (t he bane of clean , deep
bass). As a result, we don’t require the megawatts some subs do.

What’s to know?
Well, first of all, setting up an SVS subwoofer is
pretty darn eas y. There ar e a few key t hings to get r ight though if you
want to get the most out of your sub.
Unpacking.
You’re probably eager to hear your sub, but take time to
carefully unpack everything. Save the box and shipping materials, just
in case you need to return the sub for any reason.

Studies have
shown that the deepest and flattest bass response is typically attained
when a subwoofer is placed within a few feet of one of your room’s
corners (leave about 3” in the back for port and cable clearance with any
wall or other surface). A corner near your favorite seat is often the best
of all locations. Whether you put the sub in front or to the rear of your
seating area makes surprisingly little difference. Deep home theater
bass, like that from “5.1 cha nnel” DVDs is non-directio nal. You can’t
tell where it is coming from, even though you can hear, and feel it.

If you are running a pair of SVS subwoofers (Fig. 2), you will need to
use a standard “Y” cable adapter (d.) The best adaptor to use for this task
has one male RCA connection and two female RCA outputs. From the
“Y” cable you can run a standard 75 Ohm RCA to RCA signal cable (e.)
to each sub, thus “splitting” the Low Frequency Effects (LFE ) and o ther
bass signals from your receiver and effectively feeding both subwoofers
with the same signal. Contact us for hints on optimizing twin subs.

“
Level Calibration
” isn’t only for tech minded folks, it’s
proper configuration of your home theater sound system. Fortunately,
adjusting channel output bala nce (essentiall y all “calibration” a mounts to)
is as simple to do as it is important. The first order of business is making
sure your DD/DT S surr ound sound system is set up p rop erly. W e rec ommend you consult your audio/video receiver (or processor) manual to refresh on the procedures to do this. Generally, this requires ensuring the
receiver’s test tones, or a special test disk (like Ovation Software’s
play back at the same volume from each of your system’s speakers.
That’s speakers at left, center, right, left surround and right surround (and
if equipped, one or two rear channels), plus the subwoofer . (More on sub
level in a second) . Skip to p age 9 ( “Po were d B o x Featur es” ) if you a re n’t
familiar with your sub’s amp, and come back to calibration.
Some things to check as you get ready to calibrate:
•
Are your speakers set correct to the correct “size”?

“Small” or “Large”. Selecting the size accordingly will ensure bass

theater audio setup. It’s akin to a tire pressure gauge for your car
(you don’t set your tires by “feel” right?). Set the meter to “Slow”
and “C-weighting” (and turn the dial to 70 or 80dB depending on
your test tone source). Haven’t got the meter yet? Order one
from your dealer, or SVS . We prefer the analog instead of the
digital display model.
Getting ready to start now: Make sure your receiver/processor master volume is set
at “00 dB” or some other easy to remember “reference level”. Finally, ensure your
SVS’s volume/gain control is set no more than 1/4 to 1/3rd up, for now. It’s also critical to check the subwoofer level cont rol of your surrou nd receiver before you begin the
test tones. Set the receiver’s subwoofer output signal no higher than “-6 dB” initially
(that’s one quarter way up, given a typical receiver’s channel level limits of –12 dB to
+12 dB) . Your LFE “trim” or “peak limiter”, if you have one, should be set to 0dB
(with the least effect). This can be changed later i f needed. Turn off any sound-field
processing schemes, “mid-night mode”, “DRC” (dynamic range control) etc. If it is an
option in your system, route your LFE to the “Subwoofer only”, not “Mains + Sub”.
Now play your receiver's internal test tones so you have something to measure
with your SPL meter. Or, better yet, buy a test DVD such as the Avia. A test disk’s
tones ensure your entir e signal path, from the DV D player to your speakers, is set correctly. Whatever you use, when the tones start alternating from speaker to speaker
(watch your sound meter now), set each sp eaker’s volume to about 75 dB (o r 85dB if
using Avia) by using the receiver’s d edicated channel level controls (leaving receiv er’s
master volume the same). We recommend you turn down the receiver’s subwoofer
output level before you significantly lower your sub’s volume/gain control. This helps
keep distortion sent to your SVS at a minimum. You should not be set this control
much lower than –6 dB ho wever, since some downward adju stment maybe be needed
to fine tune levels later. If your subwoofer reading is still too high, then turn down the
sub’s amp volume a little with each run.

But what’s “too high”?? Tastes vary, and so do movie soundtracks, but your SVS
is capable of tremendous levels of low distortion, low frequency bass — far more than
most consumer-quality subwoofers. Take advantage of this, especially if you like action
movies or music with lots of “.1” channel (LFE) bass action, and give the sub a bit more
“bump” during calibration. Keep in mind too that the human ear is relatively insensitive
to low frequencies. This, and the fact most folks don’t watch movies at Dolby Digital
reference level (“theater loud”), means upping the bass up a few dBs usually yields a
more satisfying movie and music experience at more restrained playback levels..
What sub levels do we recommend? If you watch movies at moderate sound lev-
els, a good start is a range of +1dB to +3dB above your other channels (as measured
with your sound meter). This means the test tone will waiver about 78 dB for the sub-

especially i f running a single subwoofer. Bass “cancellation” will var y by room
shape, volume, and the bass frequency. No one setting is likely to ever be perfect.
One technique to optimize phase is to find a nice “bassy” loop (such as the menu of
the “Godzilla” movie DVD) and measure the loop’s SPL re sponse at various bass
peaks. As the loop runs, have an assistant adjust phase in small steps while you
measure. When you s ee the most response on a given bass p as sa g e, typ ically that’s
the setting with the least cancellation (for the frequencies of the demo loop).
Line In/Out. Use either of the sub’s “Line In” jacks to connect the subwoofer to the
output jack of your receiver/processor. Feeding just one input is enough. If you are
using a conventional amp and/or a stereo setup you can use the “Line Out” jacks to
send sound (filtered of deep bass information) back to your system amp. A simple
“:RCA to RCA” cabl e is al l you need for either type configur ation.
Auto On. Your SVS Powered Box allows itself to be in an “Auto-On” mode… o r
“On” all the time. With the former setting (the switch in the “Auto” position) your
subwoofer will “sense” that a DVD or CD etc. has begun and switch its audio circuits
on immediately (the “h ard” p ower s witch m entioned below must be on , naturally). A
few minutes af ter a movie, the Auto-On light will turn Red, switching the sub back
off. When running (and sensing a signal) t he Auto-On LED will be green. Sometimes, with very low listening levels, your subwoofer might not get enough of a bass
signal from your surround sound proce ssor to “trip” the Auto -On circuit. Should yo u
ever find this to be the case, you may leave this switch to “On”, or turn up the receiver’s subwoo fer output level some (be sure to recali brate channels levels with your
meter afterwards).
Crossover enab le switch. If you all ow your DD/DTS surround-sound receiver or
processor to manage bass freque n cies (again, highly recommended), this switch
should be set to “Disabled”, eliminating the effects of the “Crossover Frequency”
knob and allowing your sub to reproduce just what it’s fed from the receiver. If you
use the sub in a two channel (stereo only) configuration, then “Enable” the crossover
and adjust the knob to best blend the sub into the output of your speakers.
High level inputs/out puts. Not commonly used today, but binding posts are there in
case you don’t have low-level inputs /outputs on your re ceiver/processor. Typically
utilized only if you ar e not using a DD/DTS compatible system.
Power. This heavy-duty two-position switch next to the power cord will completely
cut the power to your sub amp. Flip this switch to off before you ever move the sub
or change inputs or outputs.
A/C connection. Plug yo ur sub into a dedicated electrical outlet. “Convenience”
outlets of typical receivers often don’t provide the nee ded current. Do not use these.
Fuse. User replaceable, contact your dealer if you have trouble finding one. The
fuse can be accessed by a small door immediately next to the power cord fitting
(where you should also find a spare one for your use).

Parametric Equalizer (select PB12-Plus subs only). Important enough and
challenging enough, this feature gets its own section! “PEQ” allows you to tame a “peak”
in your room’s natural frequency response. Peaks are quite common, especially in large
rooms or ones where your sub is far from your listening position. NOTE: A Sound Pressure Level meter is a must for proper use of the PEQ, so get one before you tackle this
control. TO DISABLE THIS CONTROL: Set the “LEVEL” control in the Parametric
EQ feature until it stops on “MIN” — thus ensuring you do not inadvertently cause poor
frequency response until such time as you properly configure the PEQ.
First you might ask yourself, “why use a PEQ?” The reason is quite simple. Your room.
Most times even a superlative subwoofer which measures very evenly (we say “flat”) in
an open domain (no reflective boundaries) will not measure the same in your home th eater
or music room. Instead, colliding bass waves can build up and cause a “peak”. This is
where a parametric equalizer hel ps out. A PEQ is an electronic circuit which allows the
user to manipulate the input signal so the acoustical output is more desirable for their environment, in many cases allowing the worst peak to be “flattened”. By manipulating the
input signal with your PEQ you can cut a wide or narrow peak in response located somewhere in the frequency range of the equalizer. Importantly, the equalizer found your sub
only allows reduction of peaks, and is “cut only”, not a boost device.
Measure the room’s response. As indicated above, you must have a firm understand-
ing of your room’s acoustical properties before you use a PEQ. To determine your room’s
natural response properties (and your subwoofer, in that room) you will need an SPL meter
shown on Page 6, and at least a pad of graph paper and a pencil for charting as below. If
you have graphing program similar to Microsoft Excel ® this will save some time charting the response curves. Contact SVS for tips on accessing advanced audio tools you can
use for room analysis. NOTE: Use extreme caution with sine-waves and only run very
low SPLs in the 75dB-85dB region. Sine waves at high SPL’s can damage your SVS!

When measuring the room’s response use a minimum resolution of 5Hz. Figure
3 on the previous page shows a theoretical illustration of a room’s response.
Before you plot your results however, it’s important to note the Radio Shack
sound meter is not totally "linear" in i t s accuracy down low. All similar meters
are off by the similar amount depending on the frequency; so while its sensitivity
below 20Hz is not what it is at 50Hz, there is a simple way to compensate for this
deficiency. It's called a co mpensation chart.
Simply look to the below frequen ci es and add the required decibels (dBs) at the
frequency in question. So if your system seems to be measuring 70dBs with a
20Hz tone, then really it's putting out 77.5dBs. This is a VERY substantial difference, roughly TWICE the acoustical energy, requiring several times the amplifier
power to achieve. You can see then how critical the below chart is if you are using your PEQ to even out or “flatten” the room response of your bass.
Add the following to your measurements:
10Hz add 20dBs
12Hz add 16.5db
16Hz add 11.5dB
20Hz add 7.5dB
25Hz add 5dB
31.5Hz add 3dB
40Hz add 2.5dB
50Hz add 1.5dB
63Hz add 1.5dB
80Hz add 1.5dB
100Hz add 2dB
125Hz add .5dB
Explanatio n of the controls. Now that we have discussed how to measure the room’s response, the next
step is to correct the problem areas with t he parametric equalizer. Before we start turning the controls we need to understand what the
adjustments are and how they work.
“Q”. This control determines how wide the correction will be. Each “hash mark”
on the amp’s front plate represents roughly 0.1 octave adjustments. The “HI”
mark is equal to 0.1 octave (narrow) and “LO” mark is equal to .9 octave (wide).
In Figure 3 the highest peak is located at 40Hz and becomes flat again at 50Hz
(the Highest Frequency of the peak). To determine the Q adjustment the following formula is needed. More on “Q” in a moment.
Formula 1 (Highest Frequency [X] – Center Point [Y])
SV Sound
SVS PEQ Controls
Center Point (Y)
Page 13
The LEVEL control is the amount of attenuation on the signal located at the center
frequency. MIN is equal to 0dB and MAX is equal to -12dB “cut”. Each hash mark
reduces the Center Point in question by 1.5dB.
The “FREQ” control (short for frequency) is the adjustment for the center point of
the cut and should target the highest peak frequency in the room’s response. Each
hash mark for this control moves the center frequency for the desired cut 5Hz, within
a range of 20-80Hz.
Adjustments of the parametric equalizer. The first step to adjusting a PEQ is determining the “Center Point” of the cut. Determining the Center Point allows us to
establish a target, or baseline, for further adjustments. In this example (again, looking
to the graph in Figure 3), the peak frequency is roughly 40Hz.
At this stage we’ll estimate the beginning (lowest frequency) and the end (highest
frequency) of the peak. In Figure 3 the beginning would be located somewhere near
25Hz and the end, or Highest Frequency, would be near 50Hz. This would be a
25Hz bandwidth, with a Center Point located at 37.5Hz (the midpoint between 25
and 50hz). Notice that the center point of 37.5Hz is not located precisely at the peak
frequency in the response curve, which was estimated at 40Hz. Why? If we used
40Hz as our center frequency and 50Hz as our high point cutoff we would only attenuate the curve down to 30Hz. This will leave a small bump in response near 25Hz
because the correction would only be located between 30Hz to 50Hz.
Now that we determined the Center Point we can adjust the “FREQ” control knob to
37.5Hz, or between the fourth and fifth hash marks, clockwise from the left.
The next step will properly adjust the “Q” setting. We again need to use Formul a 1
and calculate the Q setting from Figure 3 using Highest Frequency and Center Point
figures just determined above.

50Hz – 37.5Hz = 0.33
37.5Hz
.33 Q … or just past the third hash mark, clockwise from the left of this control.
Now that we have successfully adjusted the Q and Frequency controls, we need to
make the final Level adjustment. In Figure 3 the adjustment should be somewhere
near –10dB to –11dB, or on the 8th hash mark from the left (1.5dB cut per hash
mark), completing the adjustments for the parametric equalizer.
Measure room response for accuracy. After all the adjustments are made we recommend you measure the room again to make sure the adjustments are correct. If the
new response curve is not acceptable then fine-tune things some. For exampl e, if the
response curve still shows a small peak you should adjust the Lev e l control again to
compensate. Make sure your overall SPL calibration is set as described earlier in this
manual, and enjoy your optimized subwoofer!

Subsonic Filter and Port Tuning
Your new SVS subwoofer not only comes with our
efficient “Tri-Power” port flares, but custom port
plugs and variable subsonic filter which allow
your sub to be “tuned” to even lower frequencies
than its stock configuration. For most people and
most rooms, your SVS is already configured for
the best blend of extension (how deep/low your sub goes) and output (how loud it
gets at a variety of bass frequencies). However, we know that bass is a very personal
taste and no two rooms will react exactly the same with any subwoofer. So we include a custom “port plug” th at , when inserted into a por t, al lows you the user to
experiment with a substantially lower “tune”.
As with all such devices, there are compromises when tuning a sub lower. Installing
a port block takes some capacity from upper reaches of bass, installing two port
blocks naturally limits upper bass response even more. So while you will indeed get
more bass down low (where DVD and music bass is more rare, but quite exciting),
you’ll sacrifice total output capacity above the stock tuning point of the sub (where
bass is more common). You should decide if the effect is pleasing on the sorts of
movies and music you enjoy.
How to do it? To insert a port plug, simply squeeze the foam on one end and press
the plug into a port flare until it is about 1” lower than the edge of the surface of the
sub. You can remove the plug by inserting your fingertips into the port flare and
squeezing and pullin g on the foam plug at the same time. Be sure to select the subsonic filter point on the back of your SVS amp which coincides correctly with your
new “tuning point”. NOTE: We strongly recommend you do NOT run a lower
subsonic filter point than your port plug configuration would dictate — especially if
you are running the subwoofer at high sound pressure levels. Moderate levels are
doubly important if you put the subsonic filter into the 12Hz mode (* contact SVS
about details on the use of this deepest mode). This simple table indicates the settings you should use in setting up your sub blockers and the subsonic filter knob.

Look to the next page for a computer simulated response chart showing the reduction of upper bass when adding a port-plug to your SVS (along with additional
woofer excursion needed to maintain lower frequencies). The bottom line? Many
customers feel the slight loss in upper bass output to be insignificant compared to the
deeper response the port block gives. We let you decide.
