    12-Inch 150-Watt Powered Subwoofer, Black

    When you want your bass down low, you need a subwoofer as part of your home audio/theater system. Monoprice has the basses covered with this 12 inch, 150 watt (RMS) Powered Subwoofer model!

    This 12" sub is capable of producing 150 watts RMS (200 watts peak) output. It has a frequency response range of 50 to 250 Hz with a low-pass crossover filter, which can be adjusted through the full range. Gain and frequency knobs on the control panel allow you to adjust the crossover filter and the power output for the optimum blend and balance of bass output with your stereo or surround speakers.

    The subwoofer has multiple input options, which allow it to be used with any existing stereo or 5.1 (or greater) amplifier system. For each input there is a corresponding output.

    High-level inputs accept a full-range signal from the amplifier's stereo speaker outputs. When connecting the unit as part of a 5.1 system, these would be taken off the Front Left and Front Right outputs in parallel to the standard pair of front speakers. The subwoofer provides its own power and includes impedance matching circuitry, so this will not reduce the power output to the front speakers or affect the overall impedance load on the amplifier. The High-Level output can be used to connect to your stereo/front speakers or you can connect them in parallel at the amplifier.

    Additionally, the subwoofer has a set of right/left Line Level inputs. If using a standard stereo system, without a special subwoofer output, you can connect these to the left and right line level outputs on the amp. The subwoofer will then combine the signals to process the mono bass signal it needs to drive the speaker. If you are using an amplifier with a single mono subwoofer line level output, simply use an RCA "Y" cable to split the output and send it to the two line level inputs on the subwoofer. The Line Level outputs can be used to daisy chain additional subwoofers to provide even more room-filling bass!

    The subwoofer is housed in an attractive wooden cabinet, with a black finish, and measures 17" x 17" x 16 7/8" (H x W x D). The driver fires out the front and is covered by a black cloth grill. A 3 1/2" sound port is positioned underneath the enclosure.

    An optional "Auto-On" function puts the subwoofer system into power-saving standby mode after about 2 minutes of no audio input detected. Alternatively, the "Auto-On" function can be disabled, allowing the unit to be on whenever the power switch is in the "on" position. A 2 amp/250 volt fuse protects the system from short circuits or power overloads.

    My audio receiver only has a single monaural audio output. This subwoofer has separate line in L and R inputs. Will this work well with my receiver? Or is an adapter of some kind needed so both L and R inputs are filled in? From what I understand, and I may be mistaken, there's no L/R difference with the audio sent to a subwoofer.

    BEST ANSWER: For anyone interested in the answer: "If you are using an amplifier with a single mono subwoofer line level output, simply use an RCA "Y" cable to split the output and send it to the two line level inputs on the subwoofer. "
    We would like to install the subwoofer in a wall located in a closet. Will that be OK? Would we have to install a speaker cover on the wall to make it work? Thanks.

    BEST ANSWER: Not exactly sure what you mean. Is your intent to place this in a closet in an adjoining room and have the bass fill another room? If that is the case, then that may work.

    I don't think that is ideal, but the bass will be better than no sub.

    I have one in the closet in the room w/one of my systems as there is no room anywhere else. I just keep the closet door open.
    Hi, if this unit is sent to New Zealand where we have 230 volts will the PSU be changed to match the local condition?
    A C on Jan 21, 2017
    BEST ANSWER: Hello, thank you for your question. Unfortunately you will need to use a separate voltage converter in order to use this product in another location like New Zealand. I apologize for the inconvenience
    CAN I CONNECT BOOKSHELF SPEAKERS TO THIS, LINE IN; OR LINE OUT ? CD PLAYER TO RCA INPUT ?

    Amazing Sub
    This sub is nothing short of astonishing. I just built a super budget theater in my living room using almost all mono-price gear: 5 in-wall speakers, this sub and all the cabling. It's my second theater and was supposed to be cheap and out of the way (My main theater is well over $20k worth of gear built with B&W Nautilus speakers, etc.).
    I bought this sub hoping it would add a little bit, but not expecting much. It's in a 28x36 foot room with ceilings vaulting to 16' so it's a ridiculous amount of space for any sub let alone a budget one. I was hoping it would just add a bit of bassy flavor. I wasn't expecting what I got.
    What I got is a complete transformation of the sound. It's richer, much deeper, can go much louder... all the things I am used to getting with a much bigger sub in a much smaller room.
    The audio world is full of things called "sub woofers" which are nothing of the sort. This $104 gem is the real deal. It's far from perfect and I wouldn't take it downstairs, but it makes plenty of low end that's not boomy. It's not the one note "bass" that you get from cheaply built/designed subs. It adds greatly to the theater and gets out of the way when it needs to. And all at a price that wouldn't buy the worst sub at most local stores.
    Amazing job! Truly amazing. I'm buying another one for my computer.

    PROS: Nice sounding, nice looking. Real bass with good note definition. Powerful. Amazing price.

    CONS: No switch to disable crossover for home theater setups where the receiver is crossing over the sub (but this is probably a non issue).
    Volume knob a bit sensitive (another non-issue since almost all receivers allow fine tuning of sub level)

    Another Monoprice winner!
    After buying a variety of very different items from Monoprice (from speaker wire to guitars to TV mounts, etc.) and having great luck with all of my purchases, I decided to try this sub to supplement the bottom end of my stereo music system in our family room. Overall, I have to say its the best $86 I could have spent improving the overall sound of this stereo system. The sub is capable of producing good quality, usable output down to about 30Hz in our room. With some playing around with settings and sub positioning, I was able to get the sub to blend reasonably well with with my audiophile quality bookshelf speakers. Together, they sound quite impressive. In terms of sound quality, I would rate it a 9 out of 10. My only complaint is that the minimum crossover frequency of 50Hz is too high if you want to run your main speakers full range and have the sub blend in without overlap. It would be nice if they could make a design change in future production runs to lower the minimum Frequency to 30 or 40Hz. I took off one point for that.



    As for those complaining that they need a Y adaptor to use with systems with one LFE output, you don't need it at all. Simply plug the LFE output into either there R or L input on the sub and it will work fine. There is no need to feed the open input with a signal.



    Overall, its a very good sub for the money. I strongly recommend it.

    PROS: Good sound

    Substantial output

    Nice cabinetry

    CONS: Crossover

    5/5
    Some say that "for the money, this is the best you can get". Well I have owned JBL, Bose, Polk Audio etc and this woofer meets the standards of all previously named companies. Given a little playing around with the crossover and volume on both the woofer and your amp, this thing will shake your house (and your neighbor's too). I live near an AFB and i hear Osprey's and Helicopters overhead daily, this reproduces that feeling accurately. Never been in an earthquake, but when it happens in the film it feels like I'm in what i think how it feels. When listening to Today's Hits you can feel you're heart beat like the beet of a drum, as well as with Techno, Classic rock, and hard rock. Jazz and Classical really comes to life in the room: feeling the low drums and instruments like you're there. Great subwoofer for addition to anyone looking to add a new experience to you're entertainment.

    PROS: Loud crossover control

    CONS: Need to buy a mono cable and splitter for most newer amps (splitter not required but I think I may feel a difference when i bypassed it, could just be me though). You can find these cheap on monoprice or Amazon.

    Good Bass, But it has Some Problems
    3/5

    PROS: Good bass response. I would be hard pressed to imagine a setup that required more bass than this in a regular home.

    CONS: Auto-On feature does not work with line level volumes. During quiet points in the movie, the sub will turn off and it takes a second for it to turn on once it detects the need to produce bass.



    Minimal hum from power source. Even with all audio cables disconnected, the sub will have a 60hz hum coming from the speakers when plugged in and turned on. This hum is not affected by changing the volume on the back of the sub. The hum is not noticable while watching TV, but in a quiet empty room you can notice it.

    Amazing for the price.
    It seems to perform as well if not better than my $250 Polk 10" sub. Wasn't sure how I felt about the sub until I calibrated the receiver. After some setting changes it made all the difference. For the price you can't beat this.

    PROS: Price.
    Fast shipping.
    Performance.

    CONS: Huge, but that is okay.

    Excellent Product!
    Heavy! Works as advertised! Great sound and easy setup. Replaced an 8" model from another vendor. What a difference!

    PROS: Great sound

    CONS: Heavy

    A lot of sub
    5/5

    PROS: nice input/output setup
    seems sturdy
    huge
    crazy price/performance ratio
    not too boomy. clearly a real sub and some thumpy excuse to waste 400w

    CONS: A few small things that take this away from being a ten:
    dust and lint magnet
    cheap look black wood finish on the top
    just the tiniest bit boomy
    crossover and gain knobs are not the clearest and it is difficult to tell exactly what you have set it to. I have some idea what the crossover is set to but there is no way to tell if it, say, 80 hz or 90hz.

    Awesome Sub for Very Little Money!
    I've had this sub up and running for a little over a year now and it's been worth every penny. I'm no huge audiophile, but I do know when music and movies sound good. Like others have said, a little tweaking here and there and I was able to get it to blend nicely with my 7.1 HT I built in my basement. Actually, all of my speakers in my basement are from Monoprice and they sound better then my Defenitive Technology speakers I have in my 5.1 HT system I have in my living room.

    PROS: Cheap, great speaker.

    CONS: My only gripe about this speaker is the feet on it. The feet come to a hard sharp point. I know they did this for carpeting, but I built my entertainment shelving in the wall with Sheetrock and these feet dig into the Sheetrock damaging it. I wish they had flat feet that came with it also. My rating of 10 is for the sub itself. I'd give the feet a 5. I'm sure I could change the feet out with something else, I've just never taken the time to see. So that's not Monoprice's fault.

    Uuuhhh....how much is that speaker again?
    12 years ago I started a home theater but never really finished it. Bought a JBL sub and had a set of 10 year old Bose Acoustimass series 5s. Bought a Pioneer THX certified receiver and a old CRT Projector, as well as built a home theater PC. Nice setup on a budget and worked for what I needed.

    So a few weeks ago the sub died. Bad power supply, a known issue with this sub. Started reading around and found decent reviews for the Monoprice Sub, so I figured for that price I would give it a try. I recently bought a Denon 2313 Receiver and since it can drive 2 subs I figured I would get the Monoprice first and go from there.

    You know what? This is a pretty good sub. It takes a good amount of tuning and placement to get it just right, but the Audessy on the receiver has helped tremendously. Its tight, not boomy and fills in what the Bose system lacks in bass. I may even buy a 2nd one if I get the bass right. I was blasting away MeatIoaf's Bat Out of Hell and and taping sheetrock in the basement when my wife came down from the 2nd floor bedroom pretty pissed off because I was rattIing the windows upstairs. I recently added a new projector and may even replace the Bose speakers ( which are getting a little buzzy) with the Monoprice in wall ones. I already bought one of their center channel in wall units and it has impressed me. If people knew the markup in audio equipment, especially speakers, they would give Monoprice and 2nd look.

    PROS: Price
    Decent Bass
    Monoprice!


    CONS: Bass not as low as I would like but its damn close.

    Great speaker, great price
    5/5

    PROS: Great sub at a very good price. Puts out tremendous bass that is easily tailored to your system using the volume and crossover controls. It was better than the unit it replaced at a fraction of the cost. Just remember to order the y-adapter cable to hook up properly. By the way, the shipping box it came in was one of the most secure I've gotten. Shipper would have had to drop it off a moving truck to damage it. Well done, Monoprice!
