About the MTX 5512-22
High thump-to-dollar ratio
High thump-to-dollar ratio
MTX's 55 Series subs give you huge boom for the buck, and the 5512-22 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 2-ohm voice coils give you more wiring options when setting up your system.
To drive this single subwoofer, we recommend a mono amplifier rated between 300 and 600 watts RMS at 4 ohms. For more information, please refer to our article on How to Match Subwoofers and Amplifiers.

Not quite the 9500 but they Rock

Have this running off a Rockford Fosgate P500x4D bridged off rear channels which is rated at 220 watts RMS but my birth sheet says it should be more like 320 RMS. I have a few competition trophies in SQ and was looking for a good budget Sub. At first I wasn't very impressed but once it was broken in and I fine tuned it a bit it hits pretty hard for just a single sub, I have definitely heard better but not in this price range.
Pros: Larger cone area, high sensitivity, decent X-max, good power handling
Cons: Just wish MTX made a grille for it

I love the design but if you look at the spec charts these things need a enormous ported box compared to a tiny sealed box. Im a ported guy so I don't know , I have them in a dual 12 ported mtx thunder enclosure that came original with the thunder5500 so I thought that These being the 55-12 would be a cool replacement but don't hit that hard
Pros: Good design
Cons: Size of box needed

Dual 2-ohm Voice Coils: This woofer features dual 2-ohm voice coils, offering wiring flexibility. When the voice coils are wired in parallel the woofer presents a 1-ohm load. When the voice coils are wired in series the woofer presents a 4-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 26.25". 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.
