10" Woofer: The Klipsch Reference series R-10SW powered sub is fitted
with a powerful 10" 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.
150 Watt Amp: The Klipsch R-10SW powered sub employs an all-digital
150 watt RMS (300 watt Peak) amplifier for high efficiency and dynamic bass
MDF Cabinet: The R-10SW 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-10SW'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 connected
- 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: The Klipsch R-10SW powered subwoofer is equipped with
a pair of line-level RCA-type inputs to connect the sub to your receiver or
- 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.
