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.

Ultimate Ultra-budget Home Theater Speakers

Pros: Price. Performance.

Cons: Shipping is a little expensive to NJ.

What a deal I got on these speakers! Perfect timing with a Monoprice sale and an addition percent off promotion. I got 3 pair of these 8250, 1 pair of the 3-way 8251, and the 8248 8" powered subwoofer. I have it all hooked up to an Onkyo HT-RC360 and added an Infinity BU1 sub for a full 7.2 setup. The 8251s are the front L/R, and the 8250s are the center, surround, and height speakers. I have about 60 hours of break-in on the 8250s and 30 hours on the 8251s and the sub. All of this was set up using the Audyssey room-correcting auto setup in my small home office of about 11'x13'.

Deciding to get the second sub to accompany my old Infinity BU1 for a 7.2 setup took some time. Then Monoprice made the decision easier by putting out an additional percent off promotion on top of their generous sale price. The dual sub setup is great. I actually have them turned down a bit, since they were a bit too powerful for my family. Action and sci-fi movies will shake the windows, shelves, and pictures on the walls! My only concern was based on some of the reviews that said the auto-on requires a fairly strong input to turn on the sub. I've gotten around that by not using the auto-on feature and hooking both subs to an outlet with a remote switch. So I'm able to turn them on and off as I desire.

I'd recommend any of the Monoprice speakers I have to anyone!

Sufficient for an apartment

Pros: -compact size
-low price
-decent build quality

Cons: -slight humming (noticable if you are looking for it and sit very close)
- it is not going to win any audiophile tests (but i think people like that will not look into this product and price range )

if you live in an apartment and you want to have a subwoofer, your options are pretty much limited. i didnt want to spend a lot of money on a sub and keep it off the whole time. So when this hit a price of 44$ i thought why not. So far i am happy with what i got. this is a decent subwoofer you can use in an apartment without disturbing your neighbours. and for the money it is worth it. i keep the volume between 10 o clock and 12 o clock and it gives plenty of low end for my living room. it is great for movies. music may be not that great but i am not complaining at this price range. if you dont have to worry about neighbours then you can get the monprice 12 incher or one of the daytons. For an average listener like me who lives in an apartment and wants to add a sub to their home movie experience., dont think twice

Pros: Fast delivery.
Great sound.
Good size woofer.

Cons: There is no line out except for an RCA (which I ended up using, thank gosh my game system had an RCA out). It has two speaker outputs but they are labeled to amplifier, which I didn't know when I purchased. It is not a line out.

This subwoofer works excellent. I used this for an arcade game cabinet and helped the low sounds really boom (bass) during gameplay. This speaker is recommended. I ordered two of them and haven't hooked up the second one yet, but will soon. Either way, you can't lose!

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

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.
