“S P EAKER IN” / ALL M ODELS  
For parallel connection of the subwoofer and main speaker wires (main speakers full range), connect  
the subwoofer input wires to the main channel, right and left, speaker outputs of your amplifier or  
to a secondary set of main speaker terminals (speaker B) if your amplifier is so equipped. Refer to  
Figure A. Alternately, you can connect the wires from your main speakers, along with the sub-  
woofers input wires, to the SPEAKER INterminals on the subwoofer. This may be more conve-  
nient if the subwoofer is closer to your speakers than it is to your electronics. Please consult your  
dealer for details regarding connection of multiple speaker cables to a common set of speaker out-  
puts. For optimal performance, use equal lengths (left and right inputs) of the same high quality  
speaker cable that you are using to connect your main speakers. Consult your Klipsch dealer for  
recommendations. Refer to “About Speaker Wire Connections” for more detail.  
“S P EAKER OUT” / KS W 1 2 AND 1 5  
If a bass limited signal (high pass filtered) is being sent to your main speakers, connect them to the  
SPEAKER OUT” terminals on the subwoofer instead of to your amplifier. Refer to the righthand  
side of Figure B. The high pass filter on these outputs will remove the bass frequencies below 100Hz  
from your main speakers, lowering distortion and increasing their dynamic range. Also refer to the  
LOW PASS” section for more detail.  
Note: Do not connect another subwoofer to these outputs as they are high pass filtered (bass  
frequencies removed).  
ABOUT S P EAKER W IRE CONNECTIONS  
!
When making any type of speaker wire connection be sure to observe proper polarity (+ to + and -  
to -). If the polarity of one of the subwoofer input wires is reversed, the output of the subwoofer will  
be diminished. Most speaker wire is color-coded or has some distinguishing feature differentiating  
the two conductors. Speaker wire connectors on most loudspeakers and amplifiers are also color-  
coded. Typically, RED is positive (+) and BLACK is negative (-), or ground. It does not matter which  
wire conductor is connected to the positive or negative connection of your equipment as long as you  
are consistent. Be sure that the connections from the amp to all of the speakers in your system are  
connected in a like manner. If this is not done, the quantity of bass will be reduced and the stereo  
image will be compromised. Be careful to avoid excess bare wire or loose strands of wire at the con-  
nections. This could cause a shorting condition between adjacent positive and negative terminals,  
damaging your speakers and amplifier.  
LINE LEVEL CONNECTIONS  
These connections should be made using high quality shielded interconnect cables terminated with  
RCA phono plugs. These cables should be as short as possible and kept away from noise generating  
electrical equipment such as digital electronics or electric motors. Consult your Klipsch dealer for  
specific cable recommendations.  
“LINE IN” / ALL M ODELS  
For best results, these jacks should be connected to a non-filtered (full-range) subwoofer or main  
channel pre-amp output on your receiver or pre-amp/processor. Refer to the lefthand side of Figure B.  
This input signal should contain the normal bass information present in the main left and right chan-  
nels. When connecting to a component that has only a single pair of pre-amp outputs, “Y” adapters  
(splitters) may be used to feed a signal to both the subwoofer and the power amplifier.  
“LINE IN” / KS W 1 0 a nd 1 2 ONLY  
You can connect a mono subwoofer output on your electronics to the L/LFE” input using a single  
interconnect cable. If there is an inadequate amount of subwoofer volume even with the level control  
set to maximum, add a “Y” cord to the subwoofer end of the cable and connect to both line inputs.  
This will provide a significant (6dB) increase in the subwoofers output level.  
“LINE OUT” / KS W 1 5 ONLY  
If a bass limited (high pass filtered) signal is to be sent to your main speakers, connect the LINE  
OUT” jacks on the subwoofer to the line level inputs on your main channel power amplifier.

S ubwoofer P la cem ent  
Your Klipsch subwoofer is designed to operate at frequencies below 120Hz, which are essentially  
omnidirectional (difficult to localize). There may be several options for placement of the subwoofer in  
your room that will effect its frequency response and output level. Corner placement improves the  
acoustic loading of the subwoofer, increasing its output and dynamic range capabilities. Placing the  
subwoofer away from walls or in the center of the room will result in the least amount of output.  
Asymmetrical placement of two subwoofers in a room may improve low frequency reproduction by  
providing a smoother and more consistent response pattern. Since even minor repositioning will result  
in an audible performance change due to room acoustics, Klipsch recommends experimentation with  
the subwoofer placement in the room.  
A general rule of thumb is to place your subwoofer in the vicinity of the speakers with which it is  
being paired. For example, a subwoofer reproducing front channel bass will generally perform better  
when placed in the same end of the room as the main speakers. As well, a subwoofer connected to  
the rear channels of a surround system performs best when positioned in the rear of the room.  
If the subwoofer is installed near your television and color distortion is noted, simply move the sub-  
woofer farther away from your television until the interference disappears.  
If your subwoofer is placed in an enclosed cabinet, provisions must be made to ventilate the heat  
radiated by the enclosed amplifier. Additionally, since some of the acoustic output is generated by the  
subs rear firing port, a minimum of several inches of space should be provided around the sub-  
woofer. If the front of the cabinet is acoustically open, the back of the subwoofer, with the port and  
amplifier controls, should be oriented in this direction.  
If your subwoofer will be used on a hard, non-carpeted surface, attach the enclosed rubber pads to  
the subwoofers feet to prevent vibration and marring.  
How t o Connect Your  
KS W S er ies S ubwoofer  
AC P ower  
Since your KSW subwoofer has an internal power amplifier, it must be plugged into a nearby AC wall  
outlet. The subwoofer should be unplugged from the AC power with the power switch in the OFF posi-  
tion during hookup and installation. To eliminate a tripping hazard, all connections should be  
unplugged from the back panel of the subwoofer if it is being moved. Avoid extremely long extension  
cords of small gauge since they may impair the performance of the subwoofer amplifier and present a  
potential fire hazard. If the subwoofer will not be used for an extended period of time, unplug the  
power cord from the AC power outlet.  
Note: 230 volt models are not supplied with an AC power cord, but are equipped with an IEC-type  
power cord socket.  
CAUTION: SINCE YOUR KLIPSCH SUBWOOFER HAS BUILT-IN ELECTRONICS, DO NOT  
PLACE IT NEAR SOURCES OF HEAT OR MOISTURE! TAKE CARE TO ROUTE THE POWER  
CORD SO THAT IT WILL NOT BE CUT, DAMAGED OR PINCHED.  
!
Types of Connect ions  
Your subwoofer may be installed using either the SPEAKER LEVEL or LINE LEVEL connection, but  
not both. The LFE connection is an optional line level connection that can be used in conjunction  
with either type of hookup. Refer to the LFE IN / BYPASS INand BASS MANAGEMENT” sec-  
tions for more detail. You can connect the subwoofer so that your main speakers will reproduce a full  
range signal (all models) or a limited range (bass filtered) signal (KSW 12 and KSW 15 only). Speaker  
level connections are used when connecting to a receiver or integrated amplifier that lacks line level  
subwoofer or pre-amp output jacks. Line level connections are often the best choice when connecting  
the subwoofer to a system comprised of a separate pre-amp/processor and power amplifier. This also  
applies to any receiver or integrated amplifier that possesses main channel pre-amp or subwoofer  
outputs. The type of connection configuration used depends upon the capabilities of your equipment  
and your performance goals.

One Channel Shown / Repeat for Opposite Channel  
 
Refer to Figure C. Depending upon the setting of the HIGH PASS SELECTswitch, these outputs  
will remove frequencies below 50Hz or 100Hz from your main speakers. This type of hookup cre-  
ates a bi-amplified system, lowering distortion and increasing dynamic range.  
“LFE IN/ “BYP AS S IN” / KS W 1 5 ONLY  
This input should ideally be connected to a low pass filtered LFE subwoofer output jack on your  
electronics. Refer to Figure C. It is typically used with the newest 5.1 (six channel) surround sound  
systems. Signals coming into this jack are not effected by the subwoofers adjustable LOW PASS  
(HZ)filter. The LFE IN”/ “BYPASS INinput and LINE INinputs are summed together so  
both connections may be used concurrently if your electronics provide you with both outputs. The  
LFE IN”/“BYPASS IN may also be used in conjunction with speaker level inputs.  
BAS S M ANAGEM ENT  
Most surround sound electronics are equipped with a bass management system that permits the  
selection of either a full or limited range (filtered) operation for each speaker, including the sub-  
woofer. When using either the subwoofers LINE INor SPEAKER INinputs, configure the main  
channels of your surround processor for the “Large” or “Full Range” setting. If the subwoofer output  
on your electronics has a “non-defeatable” low pass filter, set the LOW PASS (HZ)control on the  
subwoofer to its highest setting (120Hz). The dedicated LFE input on the KSW 15 is the exception  
to this rule. Refer to “LFE IN”/ “BYPASS IN” / KSW 15 ONLY.  
The “.1” or LFE (Low Frequency Effects) channel contains a different signal than the bass frequencies  
present in the other channels. This information can be up to 10 decibels louder than the bass signals in  
the other channels, so caution should be exercised when connecting to this output and initially adjust-  
ing the subwoofer's level control.  
Oper a t ing Cont r ols  
“LEVEL” / ALL M ODELS  
The LEVEL” control adjusts the volume of the subwoofer relative to your main speakers. Use this  
control to compensate for room acoustics, subwoofer placement and the sensitivity of your main  
speakers. This control effects the signals that are connected to any of the subwoofers inputs. It does  
not effect the volume level of your main speakers.  
Suggested control position for initial setup: 10 to 12 o' clock.  
“LOW P AS S (HZ)” / ALL M ODELS  
The LOW PASS (HZ)control is a variable filter that controls the upper frequency limit of the sub-  
woofer. Use this control to compensate for room acoustics, subwoofer placement, type of hookup and  
the capabilities of your main speakers. The filter is continuously variable from 40 to 120Hz. Proper  
adjustment of this control helps smooth the transition in the bass frequencies between your main  
speakers and the subwoofer. Setting the filter too high will cause an overlap in the bass frequencies  
reproduced by your main speakers resulting in muddy and indistinct bass. Setting this control too low  
may cause the output of the subwoofer to sound disconnected from the bass range being reproduced  
by the main speakers. In light of this, we encourage you to experiment with various settings.  
If your main speakers are being high pass filtered with an external filter, the LOW PASS (HZ)”  
control on the subwoofer should initially be set near the frequency of this filter.  
In some cases, you may elect to feed your main speakers a full range signal. In these situations, the  
LOW PASS” control should be set near the low frequency limit of your main speakers (typically at  
the lowest setting of the control with larger, full-range speakers). In all cases, experiment due to vari-  
ability in speaker placement, room acoustics and associated equipment.  
HIGH P AS S FILTERING, S P EAKER LEVEL / KS W 1 2 AND 1 5 ONLY  
If your speakers are connected to the “SPEAKER OUT” terminals on the subwoofer, they are being  
fed a bass limited (high pass filtered) signal. The “LOW PASS (HZ)” control should initially be set  
near 100Hz.  
 
“HIGH P AS S S ELECT” / KS W 1 5 ONLY  
This switch selects either 50Hz” or “100Hz” as the bass cutoff frequency for your main speakers  
when using line level connections. Refer to Figure C. This requires that your KSW 15 be connected to  
a system utilizing both the preamp output and the power amp input jacks. Typically, the higher  
“100Hz” setting is used for smaller bookshelf speakers to relieve them of the strain of reproducing  
loud, deep bass frequencies. The “50Hz” setting is typically selected for larger floorstanding speakers  
as they are better able to handle bass energy, needing reinforcement only at the lowest frequencies.  
The subwoofers high pass filter has a gentle cutoff so there is still some audible signal content in  
your main speakers below the circuit’s cutoff frequency.  
“P OW ER” / ALL M ODELS  
This switch has conventional power “ON” and “OFF” positions, as well as an automatic setting. In  
the “AUTO” position, the subwoofer will turn itself on when it receives a signal from your system.  
If no signal is sent for a period of 15 minutes, the sub will turn itself off. A red power light indicates  
a standby mode in which the amplifier will turn on when it senses a signal. Green indicates the sub-  
woofer is on and receiving a signal.  
“P HAS E” / ALL M ODELS  
This switch is used to reverse the polarity (phase) of the subwoofer relative to your main speakers,  
allowing you to compensate for any acoustic cancellation of bass energy caused by the listening  
room. Audition a recording with a prominent, repetitive bass line in your listening chair. Use the set-  
ting that yields the greatest quantity of bass (0 or 180). The proper setting of this control is affected  
by room acoustics and the placement of the subwoofer in the room. You may need to repeat this  
procedure if the subwoofer is repositioned.  
Tr oubles hoot ing  
• If your subwoofer has little or no output:  
— Double check your power (AC) and system connections.  
Make sure that the LEVEL” control is turned up.  
Make sure that the POWER” switch on the rear control panel is in the ON” or  
AUTO” position.  
— Ensure that the POWER” light on the front of the cabinet is lit. If it is not, check the AC  
fuse. When changing the AC main’s power fuse, unplug the power cord first. To access the  
fuse, use the appropriate screwdriver to unscrew the flush cap on the amplifiers fuse receptacle.  
If the fuse is blown (the filament inside the glass tube is burned through), replace it with the  
same type and value printed on the amplifier panel next to the fuse holder. NEVER INSTALL  
A LARGER FUSE THAN THE VALUE INDICATED ON THE AMPLIFIER PANEL. If the  
fuse blows again when the subwoofer is powered up, return the unit to your authorized  
Klipsch dealer for servicing by qualified personnel. If dealer service is not available, contact  
Klipsch customer service for a Return Authorization number before shipping (REQUIRED).

All KSW powered subwoofer amplifiers are protected by a thermal sensor. If they run for extended  
periods beyond their designated power rating, the thermal sensor will engage and shut down the  
subwoofer. If this occurs, turn the POWER” switch off, reduce the volume level on your electronics  
and wait five minutes before restarting the system.  
 
If the HI LEVEL” connections are in use, a polarity reversal of one of the speaker wires coming  
from your amplifier will result in diminished output from the subwoofer. Refer to “About  
Speaker Wire Connections.”  
If you experience a noticeable hum when the subwoofer is connected to your system, and if your  
system includes video equipment, disconnect the cable television line (if present) from the system.  
If the hum disappears, consult your Klipsch dealer for a ground isolator for the cable line. If this  
does not solve the problem, contact your Klipsch dealer for further advise.  
If you connect the subwoofer to a second set of speaker terminals (i.e. speaker B), and there is a  
dramatic loss of volume from your main speakers, hook the subwoofer to the same terminals as  
your main speakers on your amplifier. Alternately, you can hook your main speakers to the  
SPEAKER INterminals on the subwoofer, along with the subwoofers input cables, or switch  
to a line level connection if your electronics permit. If you are still experiencing difficulties, con-  
sult your authorized Klipsch dealer.  
Regardless of your amplifiers rated capacity, do not operate the system at the full output (highest  
volume): Amplifiers can create extremely high levels of distortion when operated at full output  
and can damage your loudspeakers.  
If you have any questions regarding the installation or connection of your subwoofer, please contact  
your Klipsch dealer or contact us directly at 800-554-7724.
