55 Series 12" subwoofer with dual 4-ohm voice coils
Our take on the MTX 5512-44 by Crutchfield's John Pollard
High thump-to-dollar ratio
MTX's 55 Series subs give you huge boom for the buck, and the 5512-44 12” subwoofer epitomizes that mindset. MTX worked hard to build a high-performance sub that adds tons of bass to your system without emptying out your bank account. And MTX protects this sub with a 2-year warranty.
Solid engineering makes great subs
MTX squeezes an oversized cone into the standard 12" frame, so the sub moves more air and gives you more bass. The woofer's movement cools the sub as it plays, so it doesn't overheat when you're rocking out. The special suspension exerts extra control when you're pushing the sub hard, so it'll handle up to 400 watts RMS. Its dual 4-ohm voice coils make it easy to connect to a mono amplifier.
To drive this single subwoofer, we recommend a mono amplifier rated between 300 and 600 watts RMS at 2 ohms. For more information, please refer to our article on How to Match Subwoofers and Amplifiers.
These are nice for the price

Dual 4-ohm Voice Coils: This woofer features dual 4-ohm voice coils, offering 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.
Terminals: The woofer features two pair of 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.
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.

The JH300 will power this subwoofer. If you wire the voice coils in parallel you present a 2-ohm load to the amplifier. This will get you 300 watts for the subwoofer. It's not the max that the sub can handle, but certainly within the usable range. [ Jeff May 26, 2014 ] Staff
