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.

Sean from Orlando, FL on 9/30/2014

Crutchfield Customer Review (What's this?)

This review compares the Klipsch RW12-II to the Infinity PS12. At the time of this review, both items have been discontinued, regardless, I feel my experience provides insight to each company's current models. The Infinity worked okay for the first 3 years, but at some point, the internal Infinity amp started making a buzz. After replacing wires, and doing a thorough troubleshoot, it was definitely a bad amp. Infinity provided no support, and the cost to replace the amp was $150 parts only. Needless to say, I'm not impressed with Infinity Powered subs (or, at least the powered amp). To replace the faulty Infinity, I purchased the Klipsch RW12-II. The Klipsch is larger but lighter. The sound is a significant improvement over the Infinity. The Klipsch seems to be play well in both quiet settings and loud displays. I like it for both music and movies. Overall, 4 stars, due to the significant discount (half off). Did not give it 5 due to how large this sub is.

Pros: Strong sub Fills our very large family room with excellent bass Lightweight construction

Cons: Large

Crutchfield Customer Review (What's this?)

Running this along with a set of Klipsch Heresy II's to help pick up the low end frequencies that the Heresy's drop off at, and it functions perfectly! Used an AudioQuest Black Lab cable, and I have it set for the Auto On feature. No hum, no BOOM, just clean sounding Bass. Excellent Sub!

Pros: Great sound, nice cabinet.

Cons: None

SoonerTom from Houston on 8/29/2014

Crutchfield Customer Review (What's this?)

Great sub for the price. I have a very large family room and the sub is excellent for impressive bass from movie sound tracks. Still trying to get my receiver set up right for 2.1 music, but based on the response so far I think it will be fine.

Pros: Crutchfield website and delivery were excellent as usual.

Crutchfield Customer Review (What's this?)

The sub sounds amazing. Will rattle the walls and very clean sounding. The issue is no owners manual or instructions. There are switches and knobs on the back that I have no idea what they do. The website doesn't list anything either.

Smashing Expectations

Jeff I from Midland, MI on 8/23/2014

Crutchfield Customer Review (What's this?)

I replaced older 400 watt Velodynes with a pair of these at my Crutchfields recommendation. I thought dropping 125 watts might make my system a bit weak. Oh no! They are fast and powerful. An excellent value, especially for the price. I was shocked at just how much better they were.

Pros: fast response, thunderous base

Cons: none

no operating book/ owner's manual

Richard B. from Jacksonville Fl. on 8/18/2014

The sound is outstanding! Igave it 5 stars, because its cost and sound. No book on line. I called and was there was no book avaible,but to down load anoyher model. Was told its opartion was the same.

Pros: I love the old type adjustment knobs. Not a remote. Easy to adjust.

Cons: no owner's book

Klipsch RWII

Cyrus B. from Plano on 8/5/2014

Crutchfield Customer Review (What's this?)

Great service and great reco by Crutchfield. I am pairing this sub woofer with two Klipsch Ref RF 52 II as Left and Right fronts with a Bose Center and Bose 501s as rears. Running them all vis a Yamaha RXV 475 Internet capable amp.

Pros: Great booming sound! Makes the house shake on some tracks, or wit thunder, lightning, booms in movies. Simple RCA plugin, power connection and settings Crutchfield tech. Guided me thro! It was plug n play. Didn't even do tend set up routine.

Cons: It's a little longer than my JBL it replaced but it's great.

This is all you will ever need

Klipsch RW-12II

Carrie from Bismarck North Dakota on 7/3/2014

Crutchfield Customer Review (What's this?)

I bought this sub at a great price with free shipping. Can't beat that! I'm using this sub with the Klipsch Icon speakers and a Klipsch SW-350 sub. It compliments the other speakers and other sub quite well. Now that I am running two subs, the house rumbles. This is a great looking and sounding sub. I highly recommend it to anyone that wants deep, clean, heart pounding bass. Buy one, you won't be disappointed!

Pros: Excellent clean bass. Sounds great with another sub.

Cons: Large footprint so you can't put it just anywhere.

Shaking the Floor

WJS from Raleigh NC on 7/3/2014

Crutchfield Customer Review (What's this?)

This is the first sub-woofer I have owned. Setup is easy, the sound is amazing. I coupled this sub-woofer with a pair of RB-81 II Klipsch speakers and it sounds like I am in the front row at a concert. WOW what a sound. Sure am glad I replaced my old speakers, you can hear things in your music you never noticed before.

Pros: Looks really great, easy to setup, really delivers the low end beat.

Cons: None

Solid, very solid

KennyDu from Georgia on 6/29/2014

Crutchfield Customer Review (What's this?)

Klipsch has been making very high quality loudspeakers for many decades, and when you pick up their high end gear, you just can't go wrong. The RW-12II is used to round out the final piece of my home theater/media room set up with Klipsch Heresey center channel and Klipsch Cornwalls on the left and right. The sound is pure and crystal clear across the entire sound spectrum. The RW filled in that low end without being "boomy".

Pros: Quality materials and high quality sound. Strongly prefer direct firing instead of down-firing.

Cons: None that I can think of.

Best 12" sub i have heard, specially for the $!

Big Boys Hobbies Metal Detectors from Oklahoma City OK on 6/29/2014

Crutchfield Customer Review (What's this?)

I have listened to many 12" subs on various receivers and this one by far is the deepest and most natural bass I have heard. GREAT buy for the $. Not sure spending $$$$ on a higher end sub is really worth it unless you just like to have the best of the best. This sub is soooo much better than my old 12" with same sized amp.

Pros: All around great sub.

Cons: Didn't buy it the first time because I am cheap. lol

Power, fidelity, more

Rick from Middleburg, FL on 6/28/2014

Crutchfield Customer Review (What's this?)

Wow! Got this Klipsch powered sub to compliment the other five K's I purchased from Crutchfield two weeks ago and couldn't be happier. I like the fullness it brings from my new Onkyo TX NR626 7.2 to replace my aging HK. The price break on this unit was too appealing to let slip away before they're gone.

Pros: Well built, powerful, affordable.

Cons: None

Tough competition

Rob from Erie, PA on 6/26/2014

Crutchfield Customer Review (What's this?)

Best subwoofer for the price. Very clean base but powerful to move a room. My living room is 14ft by 14ft and there is a kitchen with no wall holding the sound in that extends the room another 14 ft deep. Anyone complaining about the grill doesn't know how to put it on right. When I first put it on I thought the same thing but you have to push the 4 points where the clips are and they snap in for a tight fit. I only have the gain a little over half way and it fills the whole room and kitchen.

Pros: Powerful. Clean. Quality.

Cons: None.

Klipsch Reference Subwoofer

JG from Charlotte, NC on 6/24/2014

Crutchfield Customer Review (What's this?)

Another good product from the Klipsch Reference line of speakers. For medium size rooms this subwoofer is all you should need to give you that deep thunderous sound from movie soundtracks.

Pros: Discounted Price, Klipsch reputation and sound quality, size, easy to calibrate and connect to your home AVR. Crutchfield delivered as promised and with no issues! Trusted seller.

Cons: Front Speaker Grill could be better designed as its easy to come off. If its located in a higher traffic area this can be an issue. Not the copper look on the speaker w/cover removed.

Sounds great, plenty of power

JPAnderson from Lakeville, MN on 6/23/2014

Crutchfield Customer Review (What's this?)

I wanted a 12" sub to replace the JBL 12" sub that recently died on me. I am more than happy with the performance of this sub. It easily fills my living room with great lows. Well worth the price.

Pros: Great performance for the price.

Cons: I has a pretty large foot print, it takes up more space than I would like.

Bang for the buck!

RZO from Melbourne, FL on 6/2/2014

Crutchfield Customer Review (What's this?)

Very nice sub for the money! Easy to connect and sounds great.

Awesome deep rich bass. Can be fine tuned to your liking. Would recommend this to anyone.

Pros: Deep Bass

Cons: Not really a con but this thing is big!


sam from salisbury nc 28144 on 5/12/2014

Crutchfield Customer Review (What's this?)

Performs as expected. Fit most of thr reviews I read. Crutchfield delived as promised and packing was great. I would buy from Crutchfield again

Pros: Handles crossover well with Yamaha rv 673.

Cons: Grill does not fit well and can fall off. This may be due to how hard I push it sometimes. Easy to diy fix. Reason for four star instead of five.

Good bang for the buck

JohnF from Lincoln Co NC on 5/3/2014

Crutchfield Customer Review (What's this?)

Ok, I gave it 4 out of 5 stars. Probably would be 4.5 stars if I had that option. Easy to hook up, good bass, and a pretty darn good deal for this price. It would not be if it was regular price, but at this price mark, its going to be tough to beat. Keep in mind that I am also using a B&W 1000 sub and only got the Klipsch when I blew the cone on the BW and it was down. Have since rebuilt the BW with OEM parts and with both running, you can definitely tell the difference between the BW and the Klipsch. Even though the BW only has 100 watts, its smokes the Klipsch, but then its a sub that cost around a grand back in the mid 90s!. That being said, still a good deal.

Pros: Good unit at a good price and will be hard to beat in this price range at this moment.

Cons: Speaker grille connections are wimpy and with enough bass will pop the grille out. No external fuse that I can find. For 275Watts, it just doesnt seem to have the power it should for that much juice.

Nice sub

Jim from Bakersfield, CA on 4/25/2014

Crutchfield Customer Review (What's this?)

Bought this to replace an Infinity sub I had for about 8 years. This sub produces much cleaner and tighter bass than the old one. Very happy so far

Pros: Great sale price

Cons: None so far

hooked up with old receiver and speakers and even made the whole room sound better. then withYamaha aventage rxa 3020 and deftech 800/100 incredible.

Pros: awesome, no brainer set-up

Cons: using with klipsch wireless adapter, get occasional little sounds from xbox in next room, but nothing bothersome or interfering. limited to where I can place it

Good subwoofer at nice price

Robert from Collingswood, NJ on 4/15/2014

Crutchfield Customer Review (What's this?)

Works well in 2-channel stereo setup and does a great job of filling in the bottom end for a set of Klipsch RB-61 bookshelf speakers. Not using it to shake the house in a home theater system. Easy to set up.

Pros: Nice piece of gear, looks good, satisfies my needs perfectly, bought it at a nice discount.

Cons: Snap fasteners that attach the grill are flimsy and cheaply made.

Just Awesome

Incredible bass. just love this sub....



The Perfect Fit!

BUBS from Charlottesville, VA on 4/14/2014

This Klipsch powered subwoofer brings the music in my living room to life. Whether the music is originated from my TV (as in regular programs like "The Voice" or even commercials), or from my tuner, or from my CDs, there's a bass boost that seriously compliments all the other sounds from any music source. The degree of bass sound is easily adjustable or controllable, and of course, was thoroughly explained by my Crutchfield sales person. This superb piece of audio equipment should be a must for anyone who wants to enjoy the ultimate fullness and beauty of any "sound of music"! Plus, it was offered at a great price!

Pros: Great bass sound that supplements and compliments all other notes and is easily controllable so not to dominate. Looks solid. Great price.

Cons: None


Jesse from Richmond, VA on 4/1/2014

Crutchfield Customer Review (What's this?)

Still in a break in phase, but it has wonderfull punch and responce right out of the box. Little distortion when at full level, but that will dissapear when its broken in.Couldn't beat the sale price! Not too shabby looking either.

Pros: Great price and superior quality expected from a Klipsch.

Cons: None yet

Powerful Sub

Luandn from Gold River, CA on 3/31/2014

Crutchfield Customer Review (What's this?)

This sub completes my system. I did not realize how much bass I have been missing until replacing the old one with Klipsch Reference RW-12II. Crutchfield has excellent service and free shipping. 5 star

Pros: Easy setup, powerful bass, good looking sub

Cons: none

Very Pleased

Darin from Cincinnati, Ohio on 3/30/2014

Crutchfield Customer Review (What's this?)

Purchased Klipsch speakers to replace an old theater in a box system. There is no comparison and sound is nothing short of amazing. After also comparing Bose and Polk - Klipsch won out on sound quality and value. They brought our movie viewing experience to a whole new level. Watched Thor 2 the other night and when the space ship was crashing our role house was rumbling. Felt like you were there. Very pleased with this purchase.

Pros: Deep rich sound Very well made

Cons: Doesn't come with any type of useful manual. A simple diagram of the rear of the speaker would be sufficient. Not being a speaker guru had to research what the phase switch is for.

Nice subwoofer

Roger W from MD on 3/29/2014

Crutchfield Customer Review (What's this?)

Bought this to replace an older 8" Polk sub for my home theater setup. Very deep, tight bass that you can feel. You do have to play with the crossover point and volume level a bit to match your speakers, but once you get it dialed in it sounds great. I keep my volume at about 40- 50%, fills my entire room. Be careful when attaching and removing the front grill, the mounting posts are very thin and break off easily. Crutchfield sent me a replacement grill when mine broke, great customer service. Great price on this sub, I ordered on a Sunday and it got delivered 2 days later!

Pros: Plays deep and tight

Cons: Kind of big, but a 12" sub can only be so small

Great Sub!

Technogeek from Sharpsburg Ga. on 3/28/2014

Crutchfield Customer Review (What's this?)

Wow, Received this two days ago to add a second sub to my 7.2 system. Have an 11 year old 12 inch Sony sub SA-WM500 Rated 150 Watts 20-200 HZ that I thought was pretty good so I took that off line and replaced it with the 12 inch Klipsch just to compare it to the Sony and after listening for 10 minutes I could not believe my ears. This sub is so much better than my previous sub. The bass was deeper, stronger more powerful and I was getting thumped with out it being boomy. I am thrilled and am thinking about purchasing another and not using the sony sub in this room. Wow!!! I have it in a 17 by 20' room and it has no problem shaking it. Great Sub!

Pros: Powerful deep solid bass. It is large so make sure you have room but it looks great!

Cons: None

who thought you could make the 70's better

james from Waynesboro Va. on 3/24/2014

Bought this just to see if it would make a difference. The answer is sure did. I'm using this sub with a pair of Tannoy Ardens I bought in 1977.The Ardens have a 15 inch woofer and have a smooth base but the addition of the sub has given a fullness that I didn't think I was missing. This system is for music and the sub has give new life to my blues cd collection.

Pros: Easy hook up , smooth base sound

Cons: There are no cons

Suprised! $1000+ sound for $400

marco360 from Bellingham, WA on 3/22/2014

Crutchfield Customer Review (What's this?)

Didn't expect $1000+ sound for $400 on sale. Expected a boomy cheap jukebox sound but instead got very tight bass. It's only used for music, it adds a huge soundstage or dimension to a pair of Focal 806 that badly needed more bass. The bass notes hit and stop immediately, no extra added boom or resonance. Close your eyes and the bass guitar, bass drum, piano, organ, anything with below 150Hz tones sound exactly as musical instruments should, they sound like they're right in the room with you. No boomy muddy mushed out sound. Cone stops immediately as if it put the brakes on. If this has damping factor in the amp, it is definitely works. Listened to other brands and models sub $1000 range at local stores, none compared. Not being used for home theatre but suspect it can be thunderous as the level knob isn't anywhere near the mid point. It was just an impulse buy, Crutchfield had it marked down, they'll take anything back if you're not happy, I took a chance. I'm not returning this, am happy. Don't feel the least bit guilty owning what many would consider a cheapie sub in a world of $1000-$5000 subs (and more) it really is that good.

Pros: Many different methods to connect to existing equipment. Never expected this quality of bass at this low a price. Can listen for hours without ear fatigue.

Cons: Level knob is a little too sensitive A bit on the large size.

Exceeded Expectations

Curt from Ridgefield, WA on 3/13/2014

Crutchfield Customer Review (What's this?)

Product exceeded expectations. Put in Jurassic Park into my new DVD player and it was amazing when the action heated up to hear the sounds and feel the vibrations.

Pros: Easy to install. Works perfectly with home theater system. Great value for the price.

Cons: Non apparent

Klipsch Reference RW-12II

RobM from Round Rock, TX on 2/8/2014

Crutchfield Customer Review (What's this?)

I love this subwoofer. It fills my semi-large living room 20'x15' w/12' foot ceiling with great deep bass. I use the LFE hookup and was so easy to set up.

Pros: Great power at 275 watts RMS for the price.

Cons: Wife thinks it's a little bulky.

Awesome addition

Dub from Savannah, GA on 1/24/2014

Crutchfield Customer Review (What's this?)

I bought this sub to finish the Klipsch surround system. What a great sub!! Fills the room with those great lows that everyone notices. I also paired this with the wireless link, so I can place it anywhere with a plug and not have to worry about running separate cables.

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 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 ]
