    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.

    Great subwoofer and gives off a lot of rumble and bass. Makes me feel like I'm in a theater.

    Big sound in a big package

    Pros: Big bass sound. Great value.

    I was looking to replace a Bose passive bass module with something that was self-amplified and this sub fits the bill... and then some. Huge sound improvement but it comes with a HUGE unit. Be sure to check the dimensions and measurements, this thing is the size of a small ottoman and is not easily "tucked-away".

    My main TV area is in a fairly large room. Since adjusting and futzing with the sub, and the level settings on my stereo, I am really impressed by how well the sub fills the room volume with really solid bass.

    ..you gotta be kidding me!

    Pros: ..build quality...moves a lot of air

    Cons: ..none so far...a remote may be nice but hey, you can't even buy a decent remote for what this sub sells for

    ..this is just plain crazy...how can this level of build quality and performance be delivered for these $$? Maybe it's not JL audio or Velodyne and perhaps not something you'd want to integrate into a high end 2ch system but it certainly is competent to serve in any decent HT system..

    Great speaker, great price

    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!

    Best purchase!!!!!!!!!!

    Pros: Very secure shipment. Came well packaged together. Instructions are super easy to follow. I have a Onkyo HT-R280 AVR that was from a Retail Holiday HTIB. So the AVR doesn't have a powered sub (comes with a passive but still thumped ok) nor does it have a LFE dedicated sub out. This was a cost effective way for me to upgrade my home theater but keep my Okyo. This 12 in Sub was super easy to install. Took me longer to remove it from the box than the actual total install. Those hesitant on upgrading to this , trust me , BUY IT. It hooked up with using just the R + and - input, since my passive took speaker level for the dedicated sub, I thought I would of needed to hook F , R+L in, then out. NOPE!!! Pleased to say it just needed the single R + and - IN from the AVR, adjusted the power and frequency and done. Its perfect and adds just the right amount of bass to compliment my system , and in some cases needing to turn it down some. Good to know I have more power left in case I do upgrade AVR in the future.

    Cons: NONE. Easy Install, Great Sound, cabinet is well built (I am 225 lbs and took a seat on the cabinet to hear creaks for instability and its perfect) the sound again is incredible. My GF who thinks investing money into things like this are a waste of time. Even she complimented this subwoofer and purchase. Agreed that it sounded 100% times better

    Shipping: Free and very secure packaging job
    Setup: Easiest you can do of. 4-5 steps max. 15-20 min all inc. tweaking power and freq.
    Sound: PERFECT. Music , Movies, Games, all of it sounds so much better

    I am very satisfied with this purchase. When I have another 5.1 or 7.1 to setup, I will buy another
