If the MTX Audio brand is about anything, it’s bass – and the company’s TNE212D sealed enclosure system with dual 12-inch subwoofers is one of the finest examples of “bang for the buck” engineering we’ve come across in our labs. Install this box in your ride, and all that’s left is adding an amp and some wiring (the subs’ two [2]-ohm impedance was designed to draw maximum power from a mono amp, to boot).


  • Effective wallops of bass for the price
  • Terminator subs don’t require massive amounts of power
  • Attractive enclosure with carpeted surface for protection


  • Only one speaker wire terminal soldered on the inside of box
  • No woofer grilles included
  • Takes up fair amount of cargo space


What makes the Terminator car subwoofer series from MTX a serious value?

In a term, trickle-down technology. MTX’s exclusive spider plateau venting pushes air in and out of the subs’ inner workings to keep the one-and-a-half-inch voice coil cool, while the Asymmetrical Linear Drive System utilizes a flat, progressive spider and extended pole piece to produce linear, smooth movement of the polypropylene cone.

Inject these features into subs designed to play in a specified enclosure, and you have the makings of an all-in-one system that requires little beyond power to sing. The TNE212D box is constructed of 5/8-inch MDF and covered in aviation-grade black carpet, with an embroidered Terminator logo boldly proclaiming the product’s prowess.

While the system was designed so that all components function correctly together – woofers, enclosure and tuning – there are a few caveats of the MTX TNE212D you should be made aware of, mainly the box’s sheer size. This enclosure can take up quite the amount of space in the rear of a vehicle, so that means hatchback and SUV owners are the primary beneficiaries of MTX’s system.

Additionally, the subs don’t come with grilles on them, which is mainly a cosmetic element factor for many enthusiasts – but this can pose a problem if you regularly use your vehicle for any kind of cargo loading/unloading, as the speakers can get damaged if they’re poked or hit.

This dual 12-inch subwoofer enclosure is the ideal solution for those looking for the easiest way to add bass to their vehicle without resorting to self-powered sub systems, making it a good fit for enthusiasts who understand the benefits of pairing up a sub box with powerful external amplification.

MTX Audio protects this loaded enclosure by way of a two-year warranty.
