    8 Inch 60-Watt Powered Subwoofer - Black

    This is an 8" powered subwoofer capable of producing 60 watts (RMS) output. The subwoofer has a frequency response range of 50 to 250 Hz with a lowpass crossover filter, which can be adjusted from 50 to 150 Hz. 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.

    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 subwoofer is housed in an attractive black wood cabinet that measures 13.75" x 11.75" x 11.75" (H x W x D). The driver and a 2 3/4" sound port are located on the front, covered by a black cloth speaker grill.

    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.


    Please note that the manual/data sheet for this subwoofer incorrectly lists the top-end of the crossover as having a frequency of 250 Hz. In fact, the top-end of the crossover is at 150 Hz as listed on the control plate on the back of the speaker. However, the back plate of the unit indicates the low-end of the crossover as being 45 Hz, when it is in fact 50 Hz.

    Buzzing noise Fix/Solution
    If anyone is experiencing a buzzing noise while the subwoofer is on, try using a 3 to 2 prong power cord adapter. They sell them at Walmart for less than $3 I believe. This is pretty common for a lot of amplified subwoofers.

    Good luck!
    Ok, I have a bone to pick with this product. Before I begin I will start by saying I would recommend against buying this sub. I have not actually read the other reviews on this product yet so I don't know where everyone else stands, but here's where I'm at with this one

    I bought one of these along with an entire in wall speaker system. Front:6816 , Center: 6317, Mids/Rears:4619 as well as a dozen more 4619s throughout the house. Now as for every other product number mentioned there, I have nothing but great things to say. The rest of the speakers I bought are incredible. Perfect sound quality once tuned properly.

    Now as for this sub, the first one I bought with the speakers as it was the one day sale and I figured I'd give it a shot. Set it up, tuned it, worked great for about a week. I liked enough to order a second one for my other system. After I ordered the second one, the first one suddenly wasn't working anymore. After a quick check, the fuse was blown, no biggie, got some more, they're cheap enough. Nope, blew another one, tried a few more things, blew another one, simply can't get it to turn on. The second one I order came it, I hooked it up, there's some sort of ground fault or crossover in the wiring, but it's just a constant buzz. Even with nothing connected to it, to the point where I can't use it. So basically, I bought two of these and I now have two useless step stools.

    I'm not shooting down mono, I swear by this site, but unless my luck is really that bad and I just got two lemons in a row, I would say this is not one of the best products they've ever carried.

    PROS: When it works, the sound quality is amazing for a small sub.

    CONS: Reliability

    Works better than I hoped!
    I wanted to post my review, because I was really hesitant to pull the trigger on this unit based on the reviews already posted. Some people said they couldn't hear it, or it was weak, etc. For $60, though, I wondered how bad could it be?



    Cut to now, I couldn't be happier. I have this hooked to a pawn shop 7.1 Yamaha receiver I got for $80. I also had a couple of NHT Sub Zeros I wasn't using, so those became my desk speakers. This is all being fed by an iMac in my home office.



    I guess I'm not sure what people expect for $60. I have a $500 Paradigm sub in my home theater setup. I know what a sub can do. But for the size and price, this sub sounds fantastic. My expectations have really been exceeded, and I have no regrets. I listen to mainly rock/metal and a little country and hip-hop, and so far it's been great. It's more than powerful enough to keep up with the NHT's, and you can certainly hear it about anywhere in the house.



    Just my opinion, but remember, we don't always know the whole story. Stereo equipment can get complex, and people can easily hook things up wrong. Sure, there are defective units, but one guy said he couldn't hear it from a foot away. LOL - I can promise you that's not the case. This isn't one of those crappy subs that comes with those Best Buy cheapo computer speaker sets. This is replacing a Klipsch ProMedia 2.1 system that is basically wearing out.



    My only regret is I didn't do this several years ago. I can't speak to the durability yet, but performance and value are exceptional.

    PROS: Well built, lots of features for price, sound quality, price

    CONS: Ugly front grill, no mono input - make sure to order an RCY Y cable

    Inexpensive...Big....Warm Sound
    Using the RCA to RCA hook up, I love this sub. Pretty of sound for medium sized room. Nice compliment to my surround sound set up.

    worth the money
    I bought this sub to use for my SS and replace the 100W Sony sub. This sounds better. My old sub was 10 years old and died. I could tell the differrence playing call of duty and watching movies.It has plenty of rumble. BTW my SS has a single RCA connection for the sub. This hooked right up to it.Just plug it into the right or left channel. No need for adapters.

    PROS: Great sound and rumble.

    CONS: None

    Great sound, unbelievable value.
    This sub sounds pretty damn good hooked up to my computer with a set of Alesis studio monitors. Is it better sounding than my $500 home theater sub, no. But for less than $70, I have killer low end sound and I'm very satisfied. Also, this has its own volume control and passover frequency control, which are features you'd typically only see on mid to high-end subs.

    Best sub you will find under $100, hands down! I'd highly recommend this to anyone on a budget looking for a banging sub.

    Not oustanding - But more than servicable
    This is probably the cheapest subwoofer you can buy that is not coming off craigslist. Mine did not seem to hum out of the gate, but it has started a little bit in the last week (I've owned for a month or two). It is a little 'boomy', but I'm sure that's partly due to my placement choice under my desk. I do listen at very low levels since it's in my office at work, which may be why it sticks out so much from a sound perspective. I've paired this with a quality T-Amp coming out of my computer and a nice pair of Polk bookshelf speakers - so it is probably a bit under-matched from a quality perspective. Given my space, my need, and not wanting to spend $ on something I didn't really NEED - I felt this was the right price point. There are many times when the saying "you get what you pay for is appropriate". While I would argue this time it is true, I would also say that given what a decent-good subwoofer will cost you, the price of this subwoofer and it's sound/performance leads me to think I've gotten a bit more than what I've paid for......

    PROS: It's cheap and sounds OK





    CONS: It's cheap and sounds OK

    Punches above its weight class
    Good, full base, easy installation. Clean rumbling sound. Need to tune crossover and volume to personal taste.
    Bought the 8" to expand my TV sound bar. Too much sound and power for ~150 ft^2 room.
    Moved it to a ~600 ft^2 room and paired with several Monoprice Active Wall-Mount Speakers. Really good fit and sound enhancement. The 8" is doing the job for which I thought I needed the 12".

    PROS: Good, full base, easy installation

    CONS: Maybe too much power for small home theater

    Alright, but distinct buzzing sound even when off
    Shipped fast, looks nice, easy to setup but my unit buzzes continuously as long as the power switch is on. Hoping monoprice customer service can help me.

    PROS: Compact, good price, easy to setup

    CONS: Low Hum whenever its on, even when the receiver is off or the inputs are disconnected

    mono has asked me for review of small parts
    try to use HQ coax to one channel

    PROS: started with the cheapest wiring and it hummed, even in auto mode. Reviewer said use high quality coax to one channel. I did. Now the auto off works eliminating hum after 90sec, of no input. You want to get rca coax 2680 and rt angle 10586 and this little sub kicks fanny. Goes as low as my 15inchers across the room. no comparison at the price and size 20x12 HT

    CONS: Don't know if hi-level input works auto off feature
