Our take on the MTX 5512-44

by John Pollard
MTX

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.

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 their unique 5-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.

Features

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.

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.

Warranty

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.

Good Subs

Written By Richard, Macomb, MI on Wednesday, August 20, 2014
Crutchfield Customer Review (What's this?)
 
These subs are a great bang for the buck. I loved the surround and everything about the sub. I ran 2500 watts to each sub and they lasted me about a year until I decided to trade them in.
Pros:
Loud and Ignorant
Cons:
Not good on lows

Crutchfield Customer Review (What's this?)
 
MTX Audio 4ohm, 400W Rms 800W peak, 12inch. I matched it with a Profile California 1000W amp. It blew my Kenwood 12" so I bought this speaker. When I first used it it wasn't as loud, but now it bumps pretty well. The sound is good overall. The speakers looks is pretty cool and different I like the red ring because it matches my amp light. So far so good with the build quality I usually have the volume up pretty high, and it hasn't quit on me yet and I'm sure it won't. I've had this speaker now for a little over a month and bump nearly every day. If you turn it up loud enough it's enough to be a nuisance and be heard. And not to mention it vibrates your ear drums!!

Pros:
The lows are terrific!! Better than my Kenwood! I am pleased with the speaker overall.
Cons:
It doesn't hit as hard as the Kenwood I had for single short hits. My Kenwood sounded a little different in some aspects. Such as the raising or lowering of the pitch of the bass on a song. It is not as noticeable as the MTX

Great subs for the price

Written By xl_dodgeram, Poplar Bluff MO on Wednesday, October 02, 2013
Crutchfield Customer Review (What's this?)
 
MTX reminds me once again why I continue to buy MTX. Have 2 installed behind the seat in an '07 Dodge Ram 2500 Megacab. Powered by a MTX Jackhammer mono amplifier wired to 2 ohms. Sound quality is exactly what I had hoped. Maybe lack a little on really low end bass but that may be fixable with some tuning. But overall great sound for the buck.
Pros:
Value Looks Solid construction Sound

Does anyone know if a mtx jh300 will push this sub or will it be to underpowered? [ Chadg  May 23, 2014 ]
1 answer
  • 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 Staff  May 26, 2014 ]
