10" Cerametallic Woofer: The Klipsch SPL-100 powered sub houses a
front-firing 10" Cerametallic woofer for deep accurate bass. Cerametallic
consists of extremely light, rigid materials that can hold shape while being
able to deliver lower frequencies with maximum efficiency. The Klipsch
Cerametallic cone is matted to a dual-layer, copper-wound voice coil for
exceptional conductivity. The 10" woofer is fixed to a non-resonating,
stamped-steel basket that's secured to a large magnet motor for exceptional
efficiency and low distortion.
200W Class D Amplifier: The 10" woofer is powered by a built-in 200W
(RMS)/450W (Peak) Class D amplifier. The high efficiency Class D amplifier
features an analog preamp design, which maintains the original signal path for
cleaner, true-to-source reproduction. The Class D output stage ensures maximum
efficiency for maximum output, detail, and low frequency power.
Front-Firing Port: The Klipsch SPL-100 powered subwoofer features a
front-firing port for greater efficiency, bigger bass response, and flexible
placement. Proprietary internal-flare geometry minimizes port noise for clean
undistorted low frequencies. The front-firing design allows for placement
flexibility to reduce unwanted resonance from your walls or furniture behind the
MDF Cabinet: The Klipsch SPL-100 powered sub features a MDF
cabinet with a scratch-resistant, textured wood grain vinyl that seamlessly
integrates into almost any room or decor. The enclosure's reinforced MDF
construction reduces cabinet vibration for less audible coloration and improved
sonic accuracy. Shock-absorbing rubber feet on the bottom of the cabinet to help
isolate the subwoofer from your floor. The included wove cloth grille adds a
refined look and is acoustically transparent.
Controls: The level control, low pass crossover, and phase
control allow you to blend the powered subwoofer's low-frequency tones with your
system's other speakers, as well as establish the ideal level of bass. All
controls are found on the rear-panel of the powered sub.
- Level Control: The level control adjusts the
subwoofer's volume relative to the rest of your home audio system. After the
sub's level control has been set, the volume control of your AV receiver
will be the volume control for both the Klipsch powered subwoofer and your
- Low Pass Crossover: The variable low pass crossover is
adjustable from 40-120Hz. 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.
- Phase Control: 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
Connections: The Klipsch SPL-100 is equipped with line-level inputs
that can be used as a stereo RCA input or LFE input. There is also a proprietary
wireless input for connection of Klipsch's W-A2 Wireless Subwoofer Kit (sold
- LFE/RCA Input: Most of today's AV receivers have a line-level
subwoofer output (LFE). If your receiver has an LFE output, connect one end
of a subwoofer cable (sold separately) to this output and connect the other
end of the cable into the powered subwoofer's line-level input labeled
"LEFT/LFE". Set the powered sub's built-in crossover to "LFE" with this type
of connection. In the absence of a subwoofer (LFE) output on your receiver,
as an alternative hookup, you can connect Left & Right channel pre-amp
outputs from the receiver to both the "Left/LFE" and "Right" inputs on the
- Optional Wireless Subwoofer Kit: The Klipsch
WA-2 Wireless Subwoofer Kit (sold separately) allows high resolution
wireless connectivity between the SPL-100 powered subwoofer and your AV
receiver. Simply connect the WA-2's wireless receiver to the LFE or RCA output
of your AV receiver and the WA-2's wireless transmitter to the SPL-100 powered
sub. By utilizing the WA-2 Wireless Subwoofer Kit, you won't have to run a
subwoofer cable from your AV receiver to the powered subwoofer. The WA-2 is a
2.4 GHz product designed to wirelessly transmit a signal up to a 50 foot
Note: Both the powered sub's LFE/RCA and wireless WA-2 inputs can
be utilized, giving you the ability to use a single subwoofer with multiple
systems in the same room. For example, you can use the wireless WA-2 input
for your home theater set up and the LFE/RCA input for your 2-channel
system, without needing to switch inputs when changing between systems.
LED Indicator: The front-mounted LED power indicator lets
you know when the sub is powered on or off. The LED will light green when the
powered subwoofer is on and receiving a signal. If the LED is dark and not lit,
the powered sub is off.
Auto Power On/Off: The powered subwoofer will automatically
turn On when it senses an audio signal. It will automatically go into "Standby
mode" after 15-20 minutes with no audio signal. You can also choose to turn the
powered sub On or Off manually from the rear-switch on the back.
Placement: 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. 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.
