Positioning Your Subwoofer

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.

Stereo Placement

Surround LCR and Rears Placement

Please note that room placement can have a dramatic 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.

Connections and Controls

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. 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.

Line Level Connections

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. Take care to ensure that no bare wires from any of the connections touch any other terminals, as this could cause a short and damage your equipment.

Speaker Level Connections

"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.

Care and Cleaning

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.
