Our take on the Klipsch Reference R-112SW by Crutchfield's Dave Bar
The thunder down under
When the drummer in a concert video takes his solo, you want to feel the vibrations as if you were standing next to the stage. And when aliens attack in your favorite sci-fi flick, you want to feel the floor shake beneath you. Klipsch's R-112SW powered subwoofer provides your home theater with a solid foundation of bass. Its high-output 300-watt amplifier delivers the power to bring your movies, music, and video games to life.
The sub's strong-yet-light 12" Cerametallic™ woofer is designed for quick, precise movement for more accurate sound. Its ceramic-coated aluminum cone helps to dampen unwanted vibrations, while the integrated dust cap adds stability and strength to resist twisting that can cause distortion. The slot-ported cabinet features an internal flare that minimizes port turbulence and noise for cleaner bass. And the front-firing design allows for greater placement flexibility.
Easy system integration
Line-level and LFE (Low-Frequency Effects) inputs let you easily connect the R-112SW to almost any home theater or stereo receiver. Its back-panel volume, crossover, and phase controls help you fine-tune the bass to your liking, and blend its sound into your system. The sub comes housed in a durable MDF cabinet finished with a brushed black polymer veneer. A front-mounted LED power indicator makes it easy to tell when the sub is powered up and ready to rock.

12" Cerametallic Woofer: The Klipsch R-112SW features a front-firing 12" spun-copper Cerametallic woofer that is exceptionally light yet extremely rigid, while providing remarkably low frequency response with minimal cone breakup and distortion.
300 Watt Amplifier: The Klipsch R-112SW powered sub employs an all-digital 300 watt RMS (600 watt Peak) amplifier for dynamic bass performance. The built-in all-digital amplifier delivers ample power with high efficiency and true-to-source accuracy in reproduction.
MDF Cabinet: The R-112SW 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.
Front-Firing Slot Port: The front-firing slot port with proprietary internal geometry minimizes port noise for clean undistorted low frequencies. This highly efficient enclosure design produces more output using less energy.
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 loudspeakers.
- Low Pass Crossover: The variable lowpass crossover is adjustable from 40-160Hz. 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 position.
LFE/RCA Inputs: The Klipsch R-112SW powered subwoofer is 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.
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.
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.

Product reviews from the Crutchfield Labs
by Emily S.
What's better — a sound bar or individual speakers? The answer is, of course, it depends. In this article, the writer explains why she chose to replace her trusty sound bar with a 3.1...
Why did you buy this?
I've been wanting to upgrade for a while. I decided to go with Klipsch speakers after reading so many excellent reviews. Since my 12+ years Polk sub was making a loud humming noise I decided to upgrade it first. I choice the Klipsch RP-112 because the RP-115 would have been too big. My next upgrade will be the Klipsch RP- 260F to replace my Polk Monitor 70 floor speakers.Thanks you for providing great products, excellent advise and product knowledge. [ Alimayu Sep 25, 2018 ]

Was free with my order, can't go wrong!!! [ Michael Oct 24, 2017 ]
Free with speaker purchase. Sounded like a nice match based on reviews. [ donald Oct 24, 2017 ]
I was originally going to purchase the 10 inch sub with that comes the RP-150 bundle. I noticed the 12 inch sub was on sale for the same price of the 10. My living room is a great room with about 230 square feet just where the carpet is. I'm sure the 10 would be enough to deliver the boom I want and will have the punch since it is smaller. However I prefer lower bass boom/rumble. That is what I will get with the larger sub. [ ADAM Oct 23, 2017 ]
I have been building our home theatre, I've looked into various speakers did the research on capabilities and listened to my final top picks. Klipsch quality in my opinion, the long history of quality products and standing behind these products as well as crutchfield's superior quality service made this an easy purchase. [ Johanna Oct 21, 2017 ]
Archer was great and helped me make the right choice. [ ryan Oct 16, 2017 ]
Excellent reviews. Right size for replacing existing woofer. Sale price. [ Eric Steven Oct 15, 2017 ]
I have one already and need one more [ Boris Oct 01, 2017 ]
Wanted sub to go with my recent klipsch speaker purchases [ Ehren Sep 07, 2017 ]
I received one of these subwoofers free as a promotion through Crutchfield in February 2017 when I purchased two Klipsch R-28F floor standing speakers. I was highly impressed by this subwoofer, and I recently completed a 7.1 home theater system with it. I feel adding another one of these subwoofers to make it a 7.2 system will be extra icing on the cake, and help balance the bass. [ David Aug 25, 2017 ]
Customer reviews [ D Aug 22, 2017 ]
I wanted a value product. I decided to pay a little more since I will keep this for a long time. I will buy one quality sub now and consider an= second one in the future [ Jason Aug 13, 2017 ]
wow [ James Aug 03, 2017 ]
I have Klipsch now and this sub ranked very highly on multiple sights. [ Bob Jul 17, 2017 ]

This is a great sub for small to medium sized room. The quality of materials are second to none. [ Jamie Feb 27, 2017 ]
Klipsch has great sound [ Larry Feb 26, 2017 ]
i like the specs and reviews from Crutchfield on this sub, never got a Klipsch speaker system, so why not try one. My 12" Velodyne sub burned out after using it for about 17 years, i am hoping that Klipsch can match this service [ Eusebio M. Feb 25, 2017 ]
Free shipping and no tax [ Son Feb 22, 2017 ]
fun [ michael brian Feb 22, 2017 ]
Need better precise performance than the $2-300 units offer. [ Eric Feb 13, 2017 ]
Great price and reviews on product have been pretty good. I figured I would try to save a few bucks by buying one out of the scratch and dent section as I was buying one either way. So hopefully it is still in pretty good shape. . [ Kevin Dec 25, 2016 ]
After talking to Wade it was decided that this was the best setup for our size game room (Klipsch 250 5.1). [ Lonny Dec 21, 2016 ]
Adding a second companion subwoofer to my system [ Stephen Dec 16, 2016 ]

Klipsch fan looking for deep punchy bass in my surround sound setup. [ Derrell Dec 07, 2016 ]
Price point with sale plus reviews of product. [ Scott Nov 25, 2016 ]
I look at customer reviews and ratings. It's also a very quality made product from a well known manufacturer. The warranty coverage is excellent also. [ Kevin Nov 25, 2016 ]
Brand loyalty [ Adrian Nov 24, 2016 ]
Klipsch has a proven positive track record, I EXPECT NOTHING LESS FROM THEIR R-112SW. Being primarily a Smooth Jazz listener I will not need the total muscle this SW supplies, but I cannot wait to totally enjoy the TIGHT CLEAN CRISP bass playing of a N. East (4 Play), J. Pass, W.Tisdale or G.Veasley using this SW. This will be a welcomed addition to the 4K UHD TV/Blu-ray DVD 7.1 SRS system family. [ Bernadette Nov 16, 2016 ]
Klipsch quality & design [ Chris Nov 06, 2016 ]
Goes with rest of Klipsch speakers and is a good size of where it will sit. Would have ordered the 15" if I had more room. [ ROBERT G Oct 28, 2016 ]
Price, quality [ Steven Oct 13, 2016 ]
Research conducted on $500 apx. cost subwoofers. Needed to fit in tight space and look nice decor wise. [ Bunyan Oct 06, 2016 ]
Will go nicely with my Klipsch RP 260 front speakers. [ Brian Sep 28, 2016 ]
I like Klipsch products. I am buying this based upon my research and customer reviews. [ David Sep 16, 2016 ]
I wanted one of the best subwoofers, from one of the best home audio companies.That's why I chose the Klipsch Reference R-112SW. [ Jerry Sep 04, 2016 ]
I've had an older 10" Klipsch (RPW10) sub for years and love it. Decided to order this one while on sale for even more low-end and power (particularly for music listening). I doubt I will be disappointed. Love the copper cone this one has as well. [ Brian Aug 30, 2016 ]
Fell in love with the style, price, and specifications of the sub-woofer. [ Lyle Jul 17, 2016 ]
needed extra bass for my gallery speakers [ George Jun 01, 2016 ]

Frequency response and Klipsch name [ DOMENIC Dec 18, 2015 ]
To match the other Klipsch speakers I am purchasing as part of my theater's Dolby Atmos upgrade. Reviews were perfect on this unit, based on theater size and my new amp purchase I decided 2 was better than 1. [ Adam Dec 18, 2015 ]
Love me some Klipsch [ Donald`` Dec 16, 2015 ]
perceived high quality and value for my large room [ Timothy Dec 14, 2015 ]
I used to be in the industry and was a Klipch dealer. I know how they sound but have had time paying full retail :-) So the scratch and dent deal was a no brainer. [ JOHN P Dec 06, 2015 ]
5 questions already asked
1 answer I can't get any sound out of my subwoofer, is there a setting I'm missing on my receiver? I've connected the subwoofer to the Subwoofer 1 Pre Out output on the receiver and L/LFE on the subwoofer input. I have the lowpass knob as high as it will go on the sub, and I have the front and center speakers set as "small" on the received with a crossover at 90hz. Am I missing a setting on the receiver, the sub just isn't getting a signal? [ Matthew Aug 04, 2018 ]

No idea [ Thomas Feb 28, 2018 ]
This sub will rock that room, I can hear my sub shaking my living room right now! [ STANLEY Sep 03, 2017 ]
I have my R-112SW located in the basement and the sound fills the riom. Considering that you only sit 9-10 feet away from the TV or stereo system when you listen I would think that one subwoofer would do the trick. However, if you are overly concerned about the sound filling the room, you could always step up to the R-115SW, you'd be spending the $$ anyway if you get 2 R-112SWs [ MICHAEL Sep 03, 2017 ]
Hi Ryan I have mine placed in a room about 12x16 and I have the gain turned down to around 40 to 50%. This sub is so smooth and so strong I would think it would sound great in a larger area with the gain turned up a bit. Worst case, but one and see if it's enough. [ Michael Sep 03, 2017 ]
This sub when turned on at even 50% capacity creat such a wonderful balance in sound. I watched movies listened to songs and Hans Zimmer this puppy is one of the greatest buy. I highly recommend a decent receiver to optimize performance [ NASIR Sep 02, 2017 ]
On the backplate of my unit by the power input it shows110/120 - 220/240 50/60Hz. Hope this helps it is a great speaker. [ Daniel Oct 17, 2016 ]
Yes it does. It has a switch in the back for 220V. [ DE LA LLATA Oct 13, 2016 ]
I have no empirical way of measuring how close this subwoofer comes to reproducing advertised frequency, however I can say that movies are more immersive, with the subwoofer providing that extra "punch" when appropriate. Formula 1 and Nascar races are fun to watch, as the subwoofer makes you feel like you're there. Music is more real sounding as the bass produces more depth to overall experience. Overall I'm really impressed with this subwoofer! I hope this helps! [ MICHAEL Mar 24, 2016 ]
I'm not sure this will be of much help, the frequency response on the R112SW is 24-125 The following info was pulled directly from the Klipsch website. Klipsch subwoofers are equipped with spun copper, front-firing CerametallicT woofers that are exceptionally light yet rigid to provide a remarkable low-frequency response with minimal cone breakup and distortion. Each subwoofer's all-digital amplifier delivers ample power with high efficiency and true-to-source accuracy in reproduction. Their front-firing slot ports utilize exclusive internal flare technology to minimize port noise for clean, detailed sounds. Each model also houses a satin painted MDF plinth to produce incredible acoustic decoupling so the subwoofer is heard-not the room. [ JOSEPH Mar 24, 2016 ]
