Another strong member of the family          

MTX's 35 Series subs prove once again that you can pack a lot of technology into an affordable subwoofer. This 12” 2-ohm sub shows off many of the features that MTX originally developed for their top-of-the-line subs. That means you get a sub that performs the way you want, delivering great low-end bump with impressive accuracy. And MTX protects this sub with their unique 5-year warranty.

The heart of the matter

The Inverted Apex Surround increases the cone's surface area for better volume displacement and a higher SPL. This sub's sophisticated suspension system offers better control over cone movement for more refined bass. MTX's venting system keeps the voice coil cooler for optimum performance over the long haul. Put this 2-ohm model in a sealed or ported enclosure, power it with a mono amp, and you've just created a cost-effective recipe for adding a solid kick to your music.

To drive this single subwoofer, we recommend a mono amplifier rated between 250 and 375 watts RMS at 2 ohms. For more information, please refer to our article on How to Match Subwoofers and Amplifiers.

What's a component sub and why would I want one?

A component sub is simply a speaker that's designed to reproduce bass once it's installed in a compatible enclosure. Think about the impact of a movie soundtrack in a big theater or even in your own home HDTV setup. A component sub can add the same kind of power to the music in your car. And a car sub is not all about the boom that you hear on a street corner (although that's cool too) - you can pair a component sub with your choice of enclosure to get bass just the way you like it, from tight and punchy to fat and loose. And once you experience music in your car with a well-tuned subwoofer, you'll never go back.

Very conservative looking, hours great with a black interior. They sound very good in a sealed and lined box.

Pros: GOOD looking Lots of surface area

Cons: Plastic ring mars easily when installing screws No hardware included.

Product Research

Enclosure Compatibility


Terminals: The woofer features heavy-duty spring post terminals which can accept single or dual (standard 3/4" width) banana plugs, pin connectors, or bare wire up to 10-gauge.

Inverted Apex Surround: The new Inverted Apex surround allows increased cone surface area, creating more air movement and higher SPL.

Progressive Suspension: The progressive suspension controls excursion at high power, thus reducing distortion and improving sound quality.

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.

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 1.0 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 2.32 ft³ with a slot port 13-3/4" x 2-1/2" x 26-1/4". 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.


5 Year Warranty Terms: This product carries a 5-Year Prorated Warranty with the following terms:

  • Years 1-2: Products found to be defective in materials or workmanship during the first two years will be, at Mitek's option, repaired or replaced by Mitek at no charge. The warranty period does not renew, but continues on from the original date of purchase.
  • Years 3-5: The purchase price of an item which becomes defective after the first two years and prior to the end of the warranty period will be prorated and credited toward the purchase of a new MTX product. The amount of proration is determined by dividing the original purchase price by the number of months in the warranty period (60), then multiplying the result by the number of months remaining in the warranty period.
