15" Cerametallic Woofer: The Klipsch R-115SW features a
front-firing 15" spun-copper Cerametallic woofer that is exceptionally light yet
extremely rigid, while providing remarkably low frequency response with minimal
cone breakup and distortion.
400 Watt Amplifier: The Klipsch R-115SW powered sub employs an
all-digital 400 watt RMS (800 watt Peak) amplifier for dynamic bass performance.
The built-in all-digital amplifier delivers ample power with high efficiency and
true-to-source accuracy in reproduction.
MDF Cabinet: The R-115SW is housed in a durable MDF cabinet
and finished with a brushed black polymer veneer. The MDF enclosure is rigid and
protects against unwanted vibration and distortion.
Front-Firing Slot Port: The front-firing slot port with proprietary
internal geometry minimizes port noise for clean undistorted low frequencies.
This highly efficient enclosure design produces more output using less energy.
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.
- 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 lowpass crossover is
adjustable from 40-160Hz. 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
LFE/RCA Inputs: The Klipsch R-115SW powered subwoofer is
equipped with a pair of line-level RCA-type inputs to connect the sub to your
receiver or integrated amplifier.
- LFE 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.
- Stereo Input: In 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 powered subwoofer.
WA Port (optional): The Klipsch powered subwoofer is fitted
with a proprietary 4-pin "WA-Port" connector for wireless operation, using
Klipsch's optional WA-2 wireless subwoofer kit (714WA2,
sold separately). The Klipsch WA-2 wireless subwoofer kit consists of two
components; a wireless Transmitter & wireless Receiver. The WA-2 wireless
subwoofer kit makes adding the Klipsch powered subwoofer to your home theater
system much easier, because it replaces the need for a separate subwoofer cable
that traditionally must be connected between the receiver and the powered sub.
Now, you can easily place your powered subwoofer where it both sounds and looks
best in the room since you're not restricted by an audio cable.
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.
