About Klipsch....

OUR TECHNOLOGY THE SCIENCE BEHIND THE SOUND

SOUND POWERFUL. SOUND LEGENDARY
KLIPSCH PROFESSIONAL

• You are here because you're in need of our commercial-grade audio solutions.
• Cinema, permanent installation or distributed audio - Klipsch Professional series speakers are built to last and are backed by more than 70 years of Klipsch signature acoustic technology and development.

The Four Principles of Klipsch Sound

• Paul w. Klipsch believed four principles to be the foundation for great sound.
• They continue to drive the design of every new klipsch speaker, today and tomorrow.

High Efficiency / Low Distortion

• Klipsch horn technology is highly efficient, providing more accurate sound with less power and less distortion – resulting in louder, cleaner audio. Klipsch’s law: efficiency is inversely proportional to distortion.

Controlled Directivity

• Klipsch horn technology accurately directs sound to the proper locations, which, in turn, creates a more lifelike soundstage without wasting acoustic energy where sound is not needed or desired.

Wide Dynamic Range

• The softest sounds are reproduced with remarkable clarity and the loudest sounds are delivered without harshness or distortion – with the greatest possible range between the softest and loudest sounds.

Flat Frequency Response

• Audio is delivered without frequency bias – no unnatural highs, mids or lows – reproducing recorded sound as accurately as possible without colorization.

Tractrix® Horns

• Tractrix® horns have for many years been the driving force behind klipsch’s stunningly precise acoustics.
• Featured in every klipsch speaker category, except for headphones and subwoofers, this proprietary technology provides a unique combination of precision, clarity and effortless power.

Cerametallic Woofers

• A signature feature on the reference series speakers, klipsch’s cerametallic woofers exhibit a very high stiffness-to-mass ratio and superb damping, resulting in a powerful, solid bass foundation.

Wide Dispersion Surround Technology

• As the cornerstone of every klipsch surround speaker, proprietary wide dispersion surround technology (wdst) provides astounding sonic detail for rooms with less-than-ideal placement configurations.

Features

12" Woofer: 

• The Klipsch Reference series R-120SW 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 Class D Amp:

• The Klipsch R-120SW powered sub employs an all-digital 200 watt RMS (400 watt Peak) amplifier for high efficiency and dynamic bass performance.
• The built-in, all-digital amplifier of the R-120SW subwoofer delivers ample power with high efficiency and true-to-source accuracy reproduction - thus providing maximum output, detail, and power that fills your home.

Rear Firing Port: 

• The R-120SW's enclosure uses a bass reflex design with a rear-firing port for greater efficiency and bigger bass.

MDF Cabinet: 

• The R-120SW is housed in a durable MDF cabinet and finished with a scratch resistant, textured wood-grain vinyl.
• Its reinforced MDF construction reduces cabinet vibration for less audible coloration and improved sonic accuracy - giving you the ultimate listening experience that's built to last.
• There are heavy-duty rubber feet on the bottom of the cabinet to help isolate the subwoofer from your floor.
• The included low-profile front 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.

• 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 loudspeakers.

• 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.

• 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 position.

LFE/RCA Inputs: 

• The Klipsch R-120SW powered subwoofer is equipped with a pair of line-level RCA-type inputs to connect the sub to your AV receiver or integrated amplifier.

• 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 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.
