    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.

    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!

    PROS: Price. Performance.

    CONS: Shipping is a little expensive to NJ.

    Great sound
    This is a fine piece of sound equipment that has definitely enhanced our surround sound system experience

    PROS: Excellent sound, easy set-up and adjustment, very reasonable especially compared to other subwoofer units I checked out

    CONS: None so far

    60 watt Powered Subwoofer

    PROS: I needed an additional sub to replace an broken unit in my family room. This one was the perfect size and power. Adds just the right amount of base to the surround system.

    CONS: None yet, time will tell

    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.

    Works great
    Performs how I expected it to. Great product and seems well built. It was exactly what I needed since I don't care for lots of bass...although this also delivers it if you turn it up!

    PROS: Well built
    Performs how expected

    CONS: It may just be my problem...but I can't seem to tell if the Auto ON/OFF feature is working properly. I'm sure it is, but to me it seems it's always ON. Don't take this to heart since it's probably a lack of my competence.

    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

    Good value
    I read tons of reviews before I purchased. I'm not an audio guy, but this was part of an order to replace my previous HTIB setup.
    Needless to say I was not let down by the reviews. Great purchase

    PROS: Excellent sub for your money.

    CONS: Doesn't wash the dishes!

    Love it.

    PROS: Works great at low volume.
    February 26, 2014
    The quality of sound was a pleasant surprise. My install used the RCA input jacks, so I did not know how the other input would perform.

    PROS: This powered subwoofer was small and sound output was equal to many other high priced brands that were much larger. The auto on/off was a plus for my installation and worked great. This was a great bargain and is up to the quality Monoprice products.

    CONS: The grill cloth was a bit thin and was easy to damage when moved around.
