About the Klipsch KW-100

Kristen Schaub
Enjoy deep, driving bass on your next movie night
Once you hear the room-shaking bass a subwoofer adds to your home theater system, you'll never be able to enjoy movies and music the same way without one. Take Klipsch®'s KW-100, for example. This subwoofer's high-output, down-firing 10" woofer "grips" the air to fill your room with low frequency energy that's heard and felt with undetectable distortion. Add to that its 55-watt RMS amplifier, and you've got efficient, reliable bass that'll stay strong when the action starts to heat up. So you can feel the full impact of all the deep, rumbling explosions in movies like Die Hard and The Dark Knight.

Using an older receiver? No problem. The KW-100 can connect to a home theater receiver's dedicated LFE (low-frequency effects) output, or you can use line-level or speaker-level connections, so you're covered no matter when you're receiver was built.

Features

Class A/B MOSFET Amplifier: The Klipsch KW-100 powered subwoofer features a built-in discrete Class A/B MOSFET amplifier for higher efficiency and greater reliability. The built-in amplifier is rated at 55 watts RMS (225 watts Peak). The RMS power rating indicates power available on a continuous, long-term basis. The Peak power rating indicates power available for large, short-term peaks in your music or movie soundtrack.

10" Fiber-Composite Woofer: The Klipsch KW-100 powered subwoofer features a down-firing 10" fiber-composite woofer with a durable rubber surround for optimal bass. The powered subwoofer's high-output, down-firing design "grips" the air and fills a room with low frequency energy that's heard and felt with undetectable distortion.

Bass Reflex Enclosure: The Klipsch KW-100 utilizes a bass-reflex enclosure with a rear-firing  port to produce loud, deep bass. This highly efficient enclosure design produces more output using less energy.

Power LED Indicator: Located on the powered subwoofer's front-panel, this LED indicates the operating status of the unit's built-in amplifier. The LED will light red when the amplifier is in standby mode and green when the amplifier is on and receiving a signal. If the LED is dark and not lit, the amplifier is off.

Rubber Feet: The Klipsch powered subwoofer includes four self-adhesive rubber feet to help prevent against vibration.

Placement: Klipsch powered subwoofers are designed to reproduce deep bass and deliver the impact that makes your movies and music come alive. Typically, optimum performance will result if you place the subwoofer in  a corner of the room on the same wall as your front channel speakers.

Controls

Gain Control: The gain control of the Klipsch KW-100 adjusts the subwoofer's volume relative to the rest of your home audio system. If the Klipsch powered subwoofer is connected to the Subwoofer Output (LFE) on your AV receiver, first set the subwoofer volume level control in the receiver to the "half-way" or the "0-dB" position. Then increase the gain of the subwoofer until the subwoofer's volume level matches the output of your main speakers. After this setup is completed, the volume control of your AV receiver will be the volume control for both the Klipsch powered subwoofer and your connected loudspeakers.

Lowpass Crossover: The Klipsch KW-100 powered subwoofer features a variable lowpass crossover which is adjustable from 40-120Hz (24dB/octave). The crossover point chosen determines where low bass frequencies are "handed-off" from your AV system's loudspeakers to the Klipsch powered subwoofer. Set the crossover point based on the size of your systems' main left/right speakers. As a general rule, for larger, floor-standing speakers, set the crossover point between 50-90Hz. If using small bookshelf or satellite speakers for your mains, set the crossover point between 90-120Hz. The smaller the speaker, the higher the setting until the bass frequencies blend well between the loudspeakers and the Klipsch powered sub.

Note: If setting the crossover point in the receiver, turn the Lowpass Filter knob on the subwoofer to the farthest point right (120Hz).

Phase: The Klipsch KW-100 powered subwoofer has an adjustable phase control which can be set between 0° and 180°. This control is used to acoustically match the subwoofer's output to your system's main speakers. Select a position between 0° and 180°, in which the subwoofer has more output at your main listening position.

Power Auto/On/Off: The Klipsch powered subwoofer features a 3-way power switch. This is the main AC power switch for the subwoofer. This switch must be in the "On" position for the subwoofer to operate or the "Auto" position for the Auto-On feature to function. Set this switch to the "Off" position if the subwoofer will not be used for an extended period of time. 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 20 minutes with no signal.

Connections

Line-Level Input: The Klipsch KW-100 powered subwoofer is equipped with a pair of line-level RCA-type inputs. Most of today's AV receivers have a line-level subwoofer output (LFE) labeled Subwoofer Pre Out, Sub Out, or SW Out. If your receiver has this output, connect on end of a subwoofer cable to it and connect the other end of the cable into the powered subwoofer's line-level input labeled "LEFT/LFE". This connection allows the subwoofer to operate with both music and surround sound movies. In absence of a subwoofer (LFE) output on your receiver, as an alternative hookup, you can connect Left & Right channel pre-amp outputs from a receiver to the "Left/LFE" and "Right" input on the powered subwoofer.

Speaker-Level Inputs: If your AV receiver does not have an LFE out or subwoofer preamp output, you can connect the Klipsch subwoofer to the receiver via speaker-level connection, using the powered subwoofer's binding posts. Using 16-gauge or larger speaker wire, connect the Red 'positive' (+) terminal of the AV receiver's Left channel to the Red (+) terminal of the subwoofer's Left speaker-input channel. Connect the Black 'negative' (-) terminal of the AV receiver's Left channel to the Black (-) terminal of the subwoofer's Left speaker-input channel. Repeat this procedure for connecting your AV receiver's Right channel input. The terminals on the AV receiver used to connect the powered subwoofer will be the same terminals used to connect the AV receiver to your main speakers.

Note: Take care that no bare wires from any of the connections touch any other terminals, or each other, as this could damage your equipment.
