    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.

    You get what you pay for the 60 what 8 inch woofer, sounds good at times, but have the time I spend adjusting it, as it makes a humming sound all the time.

    Punches above its weight class

    Pros: Good, full base, easy installation

    Cons: Maybe too much power for small home theater

    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".

    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.

    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.

    Amplifier makes an audible 60Hz hum

    Pros: Solid construction

    Cons: Internal amplifier hums

    I'm a somewhat disappointed by this sub. I listen to music (movies sometimes, but music more), and the 60Hz hum from this speaker overwhelms the music in soft passages. My complaint is 'audiophile' in nature, true, but audiophile or not, I believe quite strongly that components of an audio system amps, disk players, and yes, speakers should be intrinsically, absolutely silent. Ironically, the 60Hz hum from this device is square in the middle of the range that it's supposed to reproduce, so formally, you can say that it does a terrible job. If you overlay the 60Hz hum on the audio signal in the quiet passages, the sum signal would look nothing like the musical input. Making matters somewhat worse, I leave the speaker powered on all the time, so I get the background hum in my room all the time. BTW, I've double checked, and this has nothing to do with the input. Line-level input, high-level input, and no input at all does not change the hum
