Overview

Our take on the Klipsch Reference RW-12II

The hard-hitting Klipsch RW-12II adds deep bass impact to all your music, movies, and video games. This Special Limited Edition Reference series powered subwoofer sports a strong-yet-light 12" fiber composite cone woofer designed for quick, precise movement, and can easily fill even a large home theater room with deep bass. Plus, it has a clean, neutral appearance that won't clash with your décor.  Klipsch's Corner Port™ technology helps minimize turbulence and distortion for clean sound. And since the port is in the front, you won't hear unwanted "boominess" from sound reverberating off your walls and floor. That means you can place this sub just about anywhere and enjoy punchy low-frequency effects.

Talk about "boom for the buck" !! I bought this in replacement of my Klipsch 10 inch and thought I would pair them together. After the a couple of blurays I think I'll stick with just the 12.

Features

12" Powered Subwoofer: The Klipsch RW-12 II active subwoofer employs a front-firing 12" fiber composite cone woofer powered by an integrated amplifier for dynamic bass from movie and music soundtracks. The Klipsch RW-12 II utilizes a bass-reflex enclosure with an advanced front-firing port to produce tight, accurate bass. This highly efficient enclosure design produces more output using less energy.

Subwoofer Controls: The Klipsch RW-12 II powered subwoofer offers Volume, Crossover, and Phase control.

  • Volume: The gain control of the Klipsch RW-12 II adjusts the subwoofer's volume relative to the rest of your home audio system.
  • Crossover: The Klipsch RW-12 II powered subwoofer features a variable lowpass crossover which is adjustable from 50-150Hz. The crossover point chosen determines where low bass frequencies are "passed-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: The Klipsch RW-12 II powered subwoofer has an adjustable phase control which can be set between 0° and 180°. This control is used to acoustically match the subwoofer's output to your system's main speakers. Select a position between 0° and 180°, in which the subwoofer has more output at your main listening position.

Low-Level & High-Level Inputs: The Klipsch RW-12 II provides both low-level (RCA) and high-level (speaker) inputs.

  • RCA/LFE Inputs: The Klipsch RW-12 II powered subwoofer is equipped with a pair of line-level RCA-type inputs. Most of today's AV receivers have a line-level subwoofer output (LFE) labeled Subwoofer Pre Out, Sub Out, or SW Out. If your receiver has this output, connect one end of a subwoofer cable to it and connect the other end of the cable into the powered subwoofer's line-level input labeled "LEFT/LFE". This connection allows the subwoofer to operate with both music and surround sound movies. In absence of a subwoofer (LFE) output on your receiver, as an alternative hookup, you can connect Left & Right channel pre-amp outputs from a receiver to the "Left/LFE" and "Right" input on the powered subwoofer.
  • Speaker Level Inputs: If your AV receiver does not have an LFE out or subwoofer preamp output, you can connect the Klipsch subwoofer to the receiver via speaker-level connection, using the powered subwoofer's 5-way binding posts. Using 16-gauge or larger speaker wire, connect the Red 'positive' (+) terminal of the AV receiver's Left channel to the Red (+) terminal of the subwoofer's Left speaker-input channel. Connect the Black 'negative' (-) terminal of the AV receiver's Left channel to the Black (-) terminal of the subwoofer's Left speaker-input channel. Repeat this procedure for connecting your AV receiver's Right channel input. The terminals on the AV receiver used to connect the powered subwoofer will be the same terminals used to connect the AV receiver to your main speakers.

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.

Auto Turn-On/Off: The Klipsch powered subwoofer features a 3-way power switch. This is the main AC power switch for the subwoofer. This switch must be in the "On" position for the subwoofer to operate or the "Auto" position for the Auto-On feature to function. Set this switch to the "Off" position if the subwoofer will not be used for an extended period of time. When this switch is in the "Auto" position, the subwoofer will automatically turn on when it senses a signal. It will automatically turn off after 20 minutes with no signal.

Rubber Feet: The Klipsch powered subwoofer is includes four self-adhesive rubber feet to help prevent against vibration.

Placement: Klipsch powered subwoofers are designed to reproduce deep bass and deliver the impact that makes your movies and music come alive. Typically, optimum performance will result if you place the subwoofer in  a corner of the room on the same wall as your front channel speakers.

I was not aware of a fuse in the back of the sub woofer? [ B  May 21, 2014 ]
No fuse on this model! [ JOE  May 09, 2014 ]
None visible. [ JOHN M  May 03, 2014 ]
No fuse in the back. [ JAMES R  May 01, 2014 ]
I haven't hooked it up yet. My house is undergoing renovation ... [ HENRY M  May 01, 2014 ]
NO FUSE. IT THE BEST SUB IN THE WORLD FOR THIS PRICE! [ EHUD  May 01, 2014 ]
Yes, the fuse is a T3.15A L 250V. Hope this helps! [ Lee  May 01, 2014 ]
I don't see one on the outside. There may be one inside. [ SALVATORE M  May 01, 2014 ]
Hey Robert, I bought this sub about a month ago and hooked it up to my Yamaha receiver. I connected the subwoofer to my receiver's pre out with a cable comprised of one RCA connector on one end and two RCA connectors on the other end. The single RCA connector plugs into the receiver and the double RCA connectors plug into the subwoofer. It works great. I bought the cable at a local electronics store. Unrelated to the RCA connectors, I want to let you know that the 12 inch woofer isn't made of aluminum, as the ad says. It is made of some non-metallic substance. Regardless, it pumps out the bass. I played Bach's Tocata and Fugue in D minor, a famous organ piece, to give the sub a workout. The whole house was shaking. I hope this helps. Yes, I would buy this again. [ David  Jan 28, 2014 ]
You just need to run 1 RCA cable from your Receiver Sub-woofer Pre-Out to the LFE/Left connection on the sub-woofer. I have mine connected this way to a Denon Receiver and works great. [ JOHN P  Jan 23, 2014 ]
no [ JAMES R  Jan 23, 2014 ]
Hi Robert! I'm not sure if this answers your question, but I ordered this same subwoofer and have this receiver : Sony STR-DN840 7.2 Channel 1050-Watt A/V Receiver (Black). I was told all I needed was this subwoofer cable: AudioQuest SUB-A 3 Meter Subwoofer Cable. Not sure if that helps or not, but I thought it would be worth a shot! [ JAMES  Jan 22, 2014 ]
Same answer I got from tech support. Thanks, Jason! [ Robert  Jan 22, 2014 ]
Robert, from my understanding, you will only need to use the LFE if your receiver has a LFE/subwoofer output. I am running a denon AVR4311, which has the LFE out, and it works great! [ JASON E  Jan 22, 2014 ]
I'm not to sure. I think u should call Tech support. [ Michael  Jan 22, 2014 ]
