Wireless Receiver & Transmitter: The Klipsch Reference
series R-12SWi powered sub features a built-in wireless receiver and comes with
an external wireless transmitter that plugs into your AV receiver's LFE output.
Thanks to this 2.4GHz wireless connectivity, your receiver can now send its LFE
audio signal to the R-12SWi powered sub wirelessly (no subwoofer cable required
between receiver and sub). Wireless range is approximately 30' at CD-quality
Note: Both, the powered sub & wireless transmitter will require AC
12" Woofer: The Klipsch Reference series R-12SWi powered sub
is fitted with a powerful 12" copper-spun IMG (injected molded graphite)
front-firing woofer for deep bass. The copper-spun IMG woofer is exceptionally
light while being extremely rigid, providing remarkable low frequency response
with minimal cone breakup and distortion. The front-firing woofer gives you
greater placement flexibility than a down-firing woofer.
200 Watt Amp: The Klipsch R-12SWi powered sub employs an
all-digital 200 watt RMS (400 watt Peak) amplifier for high efficiency and
dynamic bass performance.
MDF Cabinet: The R-12SWi 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.
Rear Firing Port: The R-12SWi's enclosure uses a bass reflex
design with a rear-firing port for greater efficiency and bigger bass.
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 40-120Hz. 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
LFE/RCA Inputs: If you prefer a hardwired connection, the
Klipsch R-12SWi powered subwoofer is also 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.
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.
