Built like a tank

The M2-12DVC 12" subwoofer comes with a tough glass fiber cone that will keep its shape when the music's turned up, so your bass stays accurate. The butyl rubber surround helps keep the woofer's movement on track, and it'll stay pliable for years to come. The stamped steel basket provides a stable home for the whole assembly, so your bass plays the way it should. 

The dual 4-ohm voice coils allow you to wire the sub for 2- or 8-ohm impedance, giving you the flexibility you need when you add more Sound Ordnance subs in the future.  Also, Sound Ordnance backs up this sub with a 3-year warranty so you can have peace of mind while you're rocking hard. 

To drive this single subwoofer, we recommend a mono amplifier rated between 200 and 375 watts RMS at 2 ohms. For more information, please refer to our article on How to Match Subwoofers and Amplifiers.

Product Research


Glass Fiber Cone: The cone is glass fiber, a rigid, yet light weight material that minimizes cone flex, resulting in low distortion and improved clarity.

Butyl Surround: The surround is butyl rubber to promote long life and durability.

Dual 4-ohm Voice Coils: This woofer features two 4-ohm voice coils that offer wiring flexibility. When the voice coils are wired in parallel, the woofer presents a 2-ohm load. When the voice coils are wired in series, the woofer presents an 8-ohm load.

Binding Posts: The 5-way binding post speaker terminals will accept spade connectors, single or dual banana plugs, pin connectors, or bare wire up to 10 gauge.

Concealing Ring: The woofer includes a removable, rubber gasket/concealing ring used to hide the woofer's mounting screws for a neat and professional looking installation.

Sealed Box Volume: The recommended sealed box volume is 1.24 ft³ (from 0.99 ft³ to 1.41 ft³ is acceptable).

Vented Box Volume: The recommended vented box volume is 1.38 ft³ with a 2.8" diameter x 9.1" long port (1.13 ft³ to 2.05 ft³ is acceptable).

Customer Q&A

Crutchfield asked: Why did you buy this?
the intended application of replacing a woofer in a home stereo warranted an extended response range that is reported in this model [ aaron  Oct 07, 2018 ]
Looking carefully at the number of reviews for each sub I look at, I was astonished to find that this sub had more stars/reviews than most others. I just received an S/O Ported Bass Bunker yesterday and found out that the 12" Kicker Comp VR I have has a damage surround. I like the specs as well. I do have to say that even with the busted surround the S/O bunker was still hitting. If that's not a sign of quality then show what is. [ David  Jul 20, 2018 ]
Great public reviews, great price. Maybe I'll regret it, but I guess we'll see. [ Anthony  Jan 26, 2018 ]
good reveiws [ JUSTIN E  Sep 19, 2017 ]
I was about to buy a JL W3 or W1 2-ohm, but for less than the cost of either speaker, I bought this 12", a SO box, some wiring hardware, box hold down brackets and a newer nicer wire stripper for another part of the install. I'll put up a review once I get it and try it, as this is my first SO product. [ Stephen  Oct 11, 2016 ]

Will the M2-12DVC fit and work in the Sound Ordnance B-17 bandpass box?
[ Jason  Oct 31, 2017 ]
1 answer
It's not recommended for use in a bandpass style enclosure but will fit the mount if you remove the original woofer.
[ Ryan  Nov 03, 2017 ]  Staff
I see you have a port ID of 2.8 recommended for this speaker at 9.1". I have a box perfect for this however am having trouble finding port tube of this size. Recommendations?

We do not offer any pre-fabricated ports with the proper dimensions. You can custom fabricate your own though. JL Audio offers a helpful article on this topic: I hope that helps. My Bio:

Is it possible to wire one of these subs to a 4ohm final load? All I can find out is how to wire it down to 2ohm or up to 8ohm.
[ RIcky  Feb 26, 2015 ]
1 answer
I forwarded your question to an Advisor and they responded with the following: With a dual 4-ohm voice coil you cannot wire it to a 4-ohm load. You are only able to wire it to a 2 or 8-ohm load. If you would like to discuss further you can contact an Advisor directly by phone (1-800-324-9695) or online chat.

Do these subs provide good low end bass?
[ Marvin  Feb 25, 2015 ]
7 answers
Yes. I have two in a ported box. Depending on the amp and setting the bass will sound a little bit different but these have the ability to crank out the low tones. They have good bass punch when theyre warm. Especially if you listen to rap. One of my friends has two MTX road thunder subs in his whip and the sound from these subs is on par with the MTX.
[ MIKE  Mar 01, 2015 ]
Yes they are great. Sounds good when I play them low volume and high volume if had the 808 great sound and hood price you can't beat that price.
[ DONALD  Feb 26, 2015 ]
For my first sub I really do enjoy it. It give me just what I need. I feel it hits the best around 34 hz. For lower than that I might not be as satisfying. But it still is a all around good sub
[ GRAYSON  Feb 26, 2015 ]
They deliver high quality low end bass It's the best sub I ever bought for the price I paid
[ FRANCISCO  Feb 26, 2015 ]
Yes they ha a nice low end base. I replaced two and love it, price is even better
[ ERNESTO  Feb 26, 2015 ]
I've had this about 2 weeks and have it mounted in the SO ported single driver enclosure (note: NOT bandpass). The fAS is 28Hz while the box is tuned to 34Hz. Using a tone generator I get solid output down to 28Hz. My son, who has the dual 12" SO bandpass box, is a bit envious of the bottom end I'm getting with the single driver. I'm using the M 2250 bridged and yes, it has good, solid low end bass. Punchy, good kick and when it's cranked a nice magic fingers on your spine. I listen to EDM, classical pipe organ, rock and various electronic artists e.g., The Chemical Method...the bottom end rocks it in all of those genres (even the lowest notes on the organ pedal which is under 30 Hz).
[ RICHARD  Feb 26, 2015 ]
Yes I am very pleased with the sound of these subs...well built for the price.Highly recommend
