KLIPSCH Reference R-8SW Compact Powered Subwoofer
OUR TECHNOLOGY THE SCIENCE BEHIND THE SOUND
SOUND POWERFUL. SOUND LEGENDARY
- 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.
- 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 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.
- 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.
- The Klipsch Reference series R-8SW powered sub is fitted with a powerful 8" copper-spun IMG (injected molded graphite) down-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 down-firing woofer gives you greater placement flexibility than a front-firing woofer.
50 Watt Amp:
- The Klipsch R-8SW powered sub employs an all-digital 50 watt RMS (150 watt Peak) amplifier for high efficiency and dynamic bass performance.
- The R-8SW 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.
Down Firing Port:
- The R-8SW's enclosure uses a bass reflex design with a down-firing port for greater efficiency and bigger bass.
- 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 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.
- 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.
- The Klipsch R-8SW powered subwoofer is equipped with a pair of line-level RCA-type inputs to connect the sub to your 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.
- 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.
- 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.
