Klipsch powered subwoofers are designed to reproduce deep bass
and deliver the impact that makes your movies and music come
alive. For optimum performance, place your subwoofer in a corner of
the room on the same wall as your front channel speakers. (refer to
Figures 1 and 2). Please note that room placement can have a dra-
matic effect on the performance of your powered subwoofer. Corner
placement, as suggested above, will increase the amount of bass
output, while placing the subwoofer along the middle of a wall, or
out in the room will decrease the amount of bass output. Experiment
with a number of different placement options and control settings
to find the one that best suits your particular room and taste. When
choosing your subwoofer’s location, keep in mind that you will need
to connect the subwoofer’s built-in amplifier to an AC power outlet.
Positioning Your Subwoofer
Optimal Connections – Klipsch SW powered subwoofers can be
connected to the subwoofer output of your electronics via the RCA
jack inputs (“LINE IN”) on the subwoofer’s rear panel (refer to
Figure 3). This can be in place of the conventional speaker wire
connections (“SPEAKER LEVEL IN”). For more information on the
controls mentioned in this manual and on bass management, see
your dealer or visit www.klipsch.com.
Conventional Speaker Wire Connections – Using 16-gauge or
larger speaker wire, connect the RED “positive” (+) terminal of
your amplifier’s LEFT channel to the RED (+) terminal of your
subwoofer’s LEFT channel input (“SPEAKER Level IN”). Connect
the BLACK “negative” (-) terminal of your amplifier’s LEFT channel
to the BLACK “negative” (-) terminal of your subwoofer’s LEFT
channel input (“SPEAKER Level IN”). Repeat this procedure for
connecting your amplifier’s RIGHT channel to your subwoofer’s
RIGHT channel input (refer to Figure 4). Take care to en0sure
Connections and Controls
WARNING: Batteries (battery pack or batteries installed) shall not be
exposed to excessive heat such as sunshine, fire or the like.
Place the equipment near a main power supply outlet and make sure
that you can easily access the power breaker switch.
WARNING: This product is intended to be operated ONLY from the
AC Voltages listed on the back panel or included power supply of the
product. Operation from other voltages other than those indicated
may cause irreversible damage to the product and void the product’s
warranty. The use of AC Plug Adapters is cautioned because it can
allow the product to be plugged into voltages in which the product was
not designed to operate. If the product is equipped with a detachable
power cord, use only the type provided with your product or by your
local distributor and/or retailer. If you are unsure of the correct
operational voltage, please contact your local distributor and/or retailer.

that no bare wires from any of the connections touch any other
terminals, as this could cause a short and damage your equipment.
“LINE IN/LFE” – This input is filtered by the built-in “Low Pass”
(LP) crossover and is designed as a general purpose input for
the subwoofer. It accepts the LFE signal output of your digital
surround electronics.
“LOW PASS” (LP) Control – This control allows the user to select
the upper frequency cutoff of the subwoofer. Frequencies above
the control setting are filtered out, allowing you to blend the
subwoofer’s output with that of your main speakers. The frequency
is selectable from 40-150Hz. For sources with an LFE output
or that use an internal crossover, the lowpass filter should be
defeated by setting the control to “BYPASS”.
“VOLUME” – This control serves as an overall volume control for
the subwoofer. It is used to match the output level of the subwoofer
to the main speakers.
“PHASE” 0/180 – This control is used to acoustically match the
subwoofer’s output to your main speakers. Select the position
either 0˚ or 180˚ in which your subwoofer has more output at the
listening position.
“Power” ON/OFF– Klipsch SW subwoofers use a detachable power
cord and do not have a main power switch. To fully remove power
from the subwoofer, the power cord must be disconnected from
the unit.
Auto/On – When this switch is in the “ON” position, the subwoofer
will remain on at all times. When this switch is in the “AUTO”
position, the subwoofer will automatically turn “on” when it senses
a signal. It will automatically turn “off” after 15 minutes with no
signal. When this switch is in the “OFF” position, the subwoofer will
remain “off” until the switch is manually turned back to the “ON” or
“AUTO” position.
LED indicator– Klipsch SW subwoofers have an LED indicator
on the front that indicates the status of the built in amplifier. The
LED will light blue when the amplifier is on and receiving a signal.
When the unit is in standby mode or turned off, the LED indicator
will turn off.
Your subwoofer has a durable vinyl finish that should only require
dry dusting or cleaning with a dry cloth. Avoid the use of abrasive or
solvent-based cleaners and harsh detergents. The brush attachment
of your vacuum should remove any dust from your subwoofer
enclosure.
