Big bass, great look

MTX engineering

Trickle-down technology makes the Terminator TN12-04 12" sub a serious value. MTX's exclusive spider plateau venting pushes air in and out of the inner works to keep the 1-1/2" voice coil cool, while the Assymetrical Linear Drive System uses a flat, progressive spider and an extended pole piece to produce smooth, linear movement of the polypropylene cone. The result is a powerful sub that keeps pumping out accurate bass, even during extended, high-level play.

To drive this single subwoofer, we recommend a mono amplifier rated between 120 and 225 watts RMS at 4 ohms. For more information, please refer to our article on How to Match Subwoofers and Amplifiers.

Great subwoofer! I have a 1500watt boss audio amp with mosfet protection on it and it's by far the best set up I've had. The only thing I would improve is getting another one

Pros: Great sound all around, good quality, and a fantastic product

Cons: None

Crutchfield Customer Review (What's this?)

Very nice over all product for the price. I bought 2 12in and installed them into a vented box. They sound great look nice and are pretty inexpensive.

Pros: Build quality, Sound great, Look Cool, Easy install.

Cons: They seem to get warm very quickly. Along with the added smell of something burning. Havnt had any problems yet.

Best bang for your buck

Crutchfield Customer Review (What's this?)

I have owned at least 10 of theese mtx terminator subs, and i have never had one blow on me, even throwing up to 1000watts rms on 2 in a box. They look clean, are very tough and the spider web coiling makes theese things basically heat proof. Even in the texas heat in my black car the amps would blow before theese puppys stopped barking. Overall good quality cheap and worth every cent. Small magnet but loud for its size. Sub is underratted for sure. Can handle twice what specs are

Pros: Lightweight, heat resistant, looks clean. Works well in almost any setup, cheap and efficent

Cons: Small magnet, do not put in ported box,

MB from Dayton, Ohio on 2/8/2014

Crutchfield Customer Review (What's this?)

Crutchfield has a lot of articles with excellent information and that helped me decide this sub. I read the articles, did the calculations and matched this sub to my amp and I am very happy with the sound. At first it was a little boomy but I read another article on how to balance and properly set the gain and crossovers on the amp and it made a big difference. Thank you Crutchfield for making so much information available .

Pros: 5 year warranty, good sound, good value


fantastic product

Pros: they bump hard and look very good in a nice box

Cons: the mtx terminator amp isnt that great. its a 400 watt and needs to be upgraded


Hands-on research

Product Research

Enclosure Compatibility


Spider Plateau Venting: Heat from the voice coil is vented through vents that surround the back of the spider. As the woofer travels back and forth, cool air is pulled in and heated air is pushed out.

Asymmetrical Linear Drive System (ALDS): The Asymmetrical Linear Drive System consists of a flat, progressive spider that improves suspension and an extended pole piece that smoothes out the cone's linear motion. The result is high output and low distortion.

Enclosure Compatibility

Sealed Box: For the best possible sound quality where space is a premium MTX recommends a sealed enclosure with an internal volume of 1.25 ft³. Sealed enclosures provide the most control over a woofer, will handle a lot of power, and provide accurate sonic reproduction, making them suitable to all types of music.

Vented Box: The recommended vented box has a net internal volume of 2.0 ft³ with a slot port 14" x 2" x 16-3/4". Vented (or ported) enclosures typically provide better overall efficiency than sealed so they are suitable for use with smaller amplifiers, giving you more bass output from less power.

2 questions already asked

Yes there is. Crutchfield offers a warranty on all products and a lot of times the product maker offers an extended warranty. I hope this can help. [ Jeremy  Jan 02, 2016 ]
From my understanding Crutchfield warranties all their products and also I actually purchased these subs and when they went out Crutchfield replaced them no problem. You want to buy something and receive the best satisfaction, then Crutchfield is the place for you. I'm always buying from this site. Reward points come in handy as well. [ RICARDO  Nov 19, 2015 ]
Thanks for your question. For information on selecting the best amp for your subs I would recommend reaching out to an Advisor by phone (1-800-324-9695) or online chat. They will be able to help determine the differences between the amp models and help you make the best choice for your system. [ Krissy  Mar 11, 2015 ]  Staff
