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 bring-  
ing music and theater home.  
We’ll help you to set up your sub right, and in no time, you’ll be giv-  
ing “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 in 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 set-  
up topics check out our Questions/FAQs page at www.sound.com.  
We touch on all the key points you need to know, and then some.  
Maybe you just want to share a bit of bass news? Or perhaps you  
have a story about your SV Subwoofer to share with us? Maybe  
something we missed in our website? No matter, feel free to send a  
note to us at: [email protected] or your dealer’s exclusive re-  
tail website in your region.  
It’s not often you can talk to the guys who made your audio compo-  
nent. In this case, we look forward to it.

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 in 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 allow for stable 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 of enclosure space (the bane of clean, deep  
bass). As a result, we don’t require the megawatts some subs do.

Setup, calibrating and integration  
What’s to know? Well, first of all, setting up an SVS subwoofer is  
pretty darn easy. There are a few key things to get right 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.  
Location. They say it’s “all about location” right? It’s the same with  
subwoofers. So, where to put it? Go for a corner if you can, and avoid  
putting your sub where it might adjoin large open areas  
.
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 channel” DVDs is non-directional. You can’t  
tell where it is coming from, even though you can hear, and feel it.  
Hook-up (see Fig. 1). There are a variety of ways to configure your  
new sub. Usually, a simple mono, shielded 75 Ohm A/V RCA type  
cable (a.) is used to take the subwoofer output of your DD/DTS  
surround sound receiver (b.) and feed the low-level input of the sub’s  
amp. There is no need to “split” the signal going to the sub (c.). You  
can feed either one of the two amp inputs, it doesn’t matter, right or left.  
NOTE: Stop now if you aren’t  
TOTALLY familiar with your re-  
ceiver’s manual. Ensure all power  
to your equipment is off when  
making these connections. Also, be certain  
your power outlet can handle a minimum of  
600 watts. (Use of “convenience outlets” on  
receivers are not recommended for your SVS).

More Setup, calibrating and integration  
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 other  
bass signals from your receiver and effectively feeding both subwoofers  
with the same signal. Contact us for hints on optimizing twin subs.  
NOTE: Now is a good time to select  
if you want “ON” (always on) or  
“AUTO ON” which turns your sub  
on only when a bass signal is present.

Level Calibration” isn’t only for tech minded folks, it’s critical to a  
proper configuration of your home theater sound system. Fortunately,  
adjusting channel output balance (essentially all “calibration” amounts to)  
is as simple to do as it is important. The first order of business is making  
sure your DD/DTS surround sound system is set up properly. We recom-  
mend you consult your audio/video receiver (or processor) manual to re-  
fresh on the procedures to do this. Generally, this requires ensuring the  
receiver’s test tones, or a special test disk (like Ovation Software’s Avia  
)
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 page 9 (“Powered Box Features”) if you aren’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”? Your re-  
ceiver/processor should allow you to indicate if your speakers are  
“Small” or “Large”. Selecting the size accordingly will ensure bass

goes to most appropriate speakers, and use the subwoofer correctly too.  
“Small” is nearly always the best setting for today’s speakers. Also, is  
your subwoofer turned “ON”? We don’t mean “is your subwoofer ampli-  
fier on?” (that’ll be important later too) but rather, is your receiver send-  
ing a bass signal to your sub amp? This can only happen if you say  
“Yes” (or “ON”) in the “Subwoofer” selection during the setup of any  
typical Dolby Digital/DTS capable receiver (you’ll need to enter your re-  
ceiver’s setup “menu” to check these critical choices).  
Is your receiver connected to the sub amp? Use a well-shielded RCA  
cable (sometimes called a “patch cord”) to connect the subwoofer output of your  
DD/DTS receiver to either input jack of your SVS’s dedicated amp. Again, you’ll  
need to “split” the bass signal with a “Y Cable” if you have a pair of subs. You  
only need feed one of the two inputs (either Right or Left) of any  
Powered Box SVS sub, these inputs are “summed” internally.  
Is your Radio Shack  
®
sound pressure level (SPL) me-  
ter ready? This tool is absolutely essential to proper home  
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 criti-  
cal to check the subwoofer level control of your surround 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 if 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 entire signal path, from the DVD player to your speakers, is set cor-  
rectly. Whatever you use, when the tones start alternating from speaker to speaker  
(watch your sound meter now), set each speaker’s volume to about 75 dB (or 85dB if  
using Avia) by using the receiver’s dedicated channel level controls (leaving receiver’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 however, since some downward adjustment 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-

ficult job of the phase control. Essentially, “phase” varies the timing of the bass  
waves coming from the sub. But don’t despair if you don’t hear much difference,  
especially if running a single subwoofer. Bass “cancellation” will vary 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 response at various bass  
peaks. As the loop runs, have an assistant adjust phase in small steps while you  
measure. When you see the most response on a given bass passage, typically 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” cable is all you need for either type configuration.  
Auto On. Your SVS Powered Box allows itself to be in an “Auto-On” mode… or  
“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 “hard” power switch mentioned below must be on, naturally). A  
few minutes after a movie, the Auto-On light will turn Red, switching the sub back  
off. When running (and sensing a signal) the Auto-On LED will be green. Some-  
times, with very low listening levels, your subwoofer might not get enough of a bass  
signal from your surround sound processor to “trip” the Auto-On circuit. Should you  
ever find this to be the case, you may leave this switch to “On”, or turn up the re-  
ceiver’s subwoofer output level some (be sure to recalibrate channels levels with your  
meter afterwards).  
Crossover enable switch. If you allow your DD/DTS surround-sound receiver or  
processor to manage bass frequencies (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/outputs. Not commonly used today, but binding posts are there in  
case you don’t have low-level inputs/outputs on your receiver/processor. Typically  
utilized only if you are 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 your sub into a dedicated electrical outlet. “Convenience”  
outlets of typical receivers often don’t provide the needed 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 Pres-  
sure 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 theater  
or music room. Instead, colliding bass waves can build up and cause a “peak”. This is  
where a parametric equalizer helps 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 envi-  
ronment, 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 some-  
where 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 chart-  
ing 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 its 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 compensation chart.  
Simply look to the below frequencies 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 differ-  
ence, 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 us-  
ing 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  
Explanation of the controls. Now that we have dis-  
SVS PEQ Controls  
cussed how to measure the room’s response, the next  
step is to correct the problem areas with the paramet-  
ric 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 follow-  
ing formula is needed. More on “Q” in a moment.  
Formula 1  
(Highest Frequency [X] – Center Point [Y])  
Center Point (Y)  
Download from Www.Somanuals.com. All Manuals Search And Download.  
SV Sound  
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 de-  
termining 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 at-  
tenuate 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 Formula 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 rec-  
ommend 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 example, if the  
response curve still shows a small peak you should adjust the Level 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 in-  
clude a custom “port plug” that, when inserted into a port, allows 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 pulling on the foam plug at the same time. Be sure to select the sub-  
sonic 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 set-  
tings 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 reduc-  
tion 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.

Bassy demo scenes to die for.  
So now what?? You’ve got one of the best theater and music bass sub-  
systems on the planet, you’re calibrated...want to see what she’ll do?  
But of course! Since finding those scenes can be a bit trying, we’ve  
compiled a list of our old favorites below. After all, calibration with test  
tones is important, but it’s movies and music this sub is itching to show  
off. Chapter stops for DVDs are shown, with movie time in hours: min-  
utes: seconds. What are you waiting for? Just hit PLAY!  
“The Iron Giant” Great family animation with SERIOUS bass,  
including strong peaks below 25 Hz. Jump to:  
1. “Chase thru the forest” Scene 8 (20:00 into the movie)  
2. “Robot Landing” (Train Impact) Scene 10 (25:40)  
3. “Green Boom” Scene 27 (1:11:40)  
Antz” Another good family movie, though not perhaps for small  
children. Extremely loud bass above 30 Hz.  
“Terror from Above”, Scene 17 (51:48)  
“The Matrix” Modern, violent, science fiction classic with plenty  
of shoot-’em-up bass blasts. Here’s some subtle and not so subtle.  
1. “Where we are grown”, Scene 12 (42:55)  
2. “Landing in fight”, Scene 15 (50:51)  
3. “Chopper shootout”, Scene 31 (1:47:15)  
“Das Boot” Arguably one of the most compelling war pictures of  
all time with bass approaching 20 Hz. Very loud, very deep.  
1. “Depth charges”, Scene 21 (59:30)  
2. “Storm surfing”, Scene 25 (1:15:15)  
3. “Hitting bottom”, Scene 17 (53:15, Side “B”)  
“Apollo 13” Moving story, with some surprisingly subtle but re-  
vealing bass where it counts.  
1. “Lift off”, Scene 13 (35:15)  
2. “Coming home”, Scene 53 (2:05:43)
