Power Acoustik MOFO-154X 15" Subwoofer

Sonic Electronix is now carrying the brand new 2011 line of Power Acoustik MOFO Series Car Audio Subwoofers. The MOFO Series 15" Subwoofer has a peak power rating of 3000 watts and a RMS rating of 1700 watts. This sub will produce some ground shaking bass and is constructed with a non-pressed pulp cone and a polyether foam surround. This woofer is also equipped with a dual 2-1/2" Voice coil and a 170 oz strontium magnet structure. Add some bumps in your trunk and enhance your cars stereo system with this Power Acoustik MOFO Series Subwoofer.

Enclosure Recommendations

All enclosures should be made of .75" (3/4") material only. When possible, make the baffle 1.5" (1 1/2") thick and add .75" (3/4") to the depth of the enclosure to compensate. All volumes INCLUDE vent/port and subwoofer displacements. DO NOT change the volume unless you plan on adding a substantial amount of bracing. For added performance, applying a coat of fiberglass resin to the interior walls will greatly improve sealing the enclosure. Adding a thin layer of poly-fill will improve response by smoothing out enclosure reflections.

Subwoofer Specifications

Subwoofer Series
Each subwoofer manufactured is part of a series. This is the name of the subwoofer's series.
MOFO (Power Acoustik)
Subwoofer Size
Refers to the diameter of the subwoofer, measured in inches.
15"
Peak Power Handling
Peak power handling refers to the amount of power a speaker can handle during a brief musical burst. The RMS power range figure is a much more reliable rating for determining the speaker's power requirements. The Peak power handling specification is typically rated per speaker unless otherwise noted.
3000 watts
RMS Power Handling
The RMS power is the amount of power the speaker requires to operate safely and properly. RMS Power Handling refers to the amount of power a speaker can handle on a continuous basis. We recommend powering your speakers or subwoofer with 80%-120% of its recommended RMS rating. The RMS power handling specification is typically rated per speaker unless otherwise noted.
1700 watts
Voice Coil(s)
Dual voice coil subs have more wiring flexibility than single voice coils subs; however, single voice coil subwoofers provide easier hookup options for wiring multiple subwoofers in parallel or series. You may also run a dual voice coil (DVC) sub in parallel, series, or combination. A quad voice coil has four voice coils and is equal to two dual voice coil subwoofers as far as wiring goes.
Dual
Impedance (Per Voice Coil)
The load value (in ohms) that the speakers present to the amplifier per voice coil - the amount of resistance to the current flow. This is a key specification as subs wired in parallel or low impedances can create problems with your amplifier and potentially void all warranties. We encourage you to ask our support department prior to purchase if you do not understand which impedance level will suit your application best.
4 ohms
Sensitivity
An efficiency or sensitivity rating tells you how effectively a speaker converts power into sound. The higher the number, the more efficient the speaker and the louder it will play with the same input power. An efficient speaker helps you maximize your available power. Most sensitivity ratings measure the speaker's output with 1 watt of input, 1 meter from the speaker. Some speakers' sensitivity is measured with 2.83 volts of input, instead of 1 watt.
 
Efficiency (1w/1m) is not an accurate indicator of a subwoofer's output capability and should not be used as a comparison to other speakers or subwoofers to determine which one is "louder".
87 dB
Xmax (millimeters)
Typically measured in millimeters, the Xmax value is the measure of a speaker cone's maximum excursion in one direction while maintaining a linear behavior.
15 mm
Subwoofer Design
This is the design of the subwoofer or the opening of the subwoofer enclosure. Each design has it's own benefits, whether it is a square, circle, or oval.

Round/Circle: This is the typical and common subwoofer design. They have a round cone and are a circle in design.

Square: These woofers are able to achieve a greater cone area in a smaller space. Because of the greater surface area, some square subwoofers will be louder than a round subwoofer of the same size.

Round / Circle
Main Cone Color
This is the color of the speaker's or subwoofer's cone.
Black
Blue
Woofer Composition
Lightweight woofer cone materials are essential for efficient operation. Poly cones produce exceptional sound and are sturdy against various changes in temperature. Paper cones are very efficient, and when treated for moisture resistance, will perform at a high level. Poly refers to polypropylene, which is thermoplastic or fibers that are polymers of propylene. IMPP refers to injection molded polypropylene, a commonly used process and material in speakers.
Non-Pressed Paper
Woofer Surround
A speakers surround is part of the suspension system. The surround protects the cone and prevents it from being displaced as it flexes out from the basket. It is usually made of a durable material like treated foam or rubber in order to withstand the strenuous job of producing bass frequencies.
Polyether Foam
Subwoofer Grille
Most subwoofers are able to accommodate a universal grille; however, some subs include a grille and others have a specific, optional grille available for purchase separately. If "yes", then the subwoofer includes a grille. If "optional (sold separately)" the matching grille will need to be purchased in addition to the sub.
No
Re-Cone Kit Available
Some higher end subwoofers have replaceable cone assemblies. In case of a blown woofer, a recone kit allows for a simple replacement, as opposed to purchasing an entire new subwoofer.
No

Recommended Enclosure Specifications

Recommended Enclosure Type
This is the recommended type of enclosure that the subwoofer should be installed into. Some subwoofers are specially designed for particular enclosures.

Sealed: These enclosures completely enclose the air inside the box. These boxes produce a tight bass.

Ported/Vented: These enclosures have a slot of air to escape from the box. The result is a sound that has more "boom".

Bandpass: These are a combination of both sealed and ported enclosures. They can be very efficient, but require tuning for the best response.

Ported / Vented
Sealed
Minimum Sealed Box Volume
This value indicates the minimum sealed box volume that the manufacturer recommends for the subwoofer. The volume is typically displayed in cubic feet.
2.00 cubic feet
Maximum Sealed Box Volume
This value indicates the maximum sealed box volume that the manufacturer recommends for the subwoofer. The volume is typically displayed in cubic feet.
2.00 cubic feet
Minimum Ported Box Volume
This value indicates the minimum ported box volume that the manufacturer recommends for the subwoofer. The volume is typically displayed in cubic feet.
4.00 cubic feet
Maximum Ported Box Volume
This value indicates the maximum ported box volume that the manufacturer recommends for the subwoofer. The volume is typically displayed in cubic feet.
4.00 cubic feet
Top-Mount Depth
The depth when installed on top of the mounting surface. Measured from the bottom of the speaker's magnet to the bottom of the mounting holes on the rim of the speaker.
8-1/4"
Cutout Diameter
The actual diameter of the hole you will need to cut out if you are creating a new mounting location for this speaker, or if you are mounting a subwoofer in a box.
14-1/8"
Shallow Mount Installation
This means that the subwoofer/speaker is designed to be installed in areas that do not have a lot of space. Shallow mount subwoofers are typically found under a seat or behind the seat in some trucks.

Shallow mount speakers will typically have a mounting depth of 2" or less, while shallow mount subwoofers will typically have a mounting depth of 3" or less.

These womp

October 3, 2014

Yeah, this sub WOMPS. Like the reviewer below me stated, these are worth every penny. I had a decision I had to make: two 12's or one 15, and I am glad I went with the MOFO, because it pounds bass like a mofo.
Built a 4 cubic foot box as the specs called for, and it pounds looooowww, thunderous bass. My ears were thanking me for my decision.

To be honest, i would just go ahead and get yourself an alpine type R 15. Much cleaner sound, most likely will take the same amount of rms or even more than this. Just my opinion.

Awesomely loud!

August 14, 2013

I have this sub in a ground shaker SQPXL115 box hooked to a Rockford Fosgate R1000-1D amp @2ohms. It hits hard enough to restrict your breathing! This is in a 2007 crown vic with all the windows down. With the windows up it is actually painful to listen to and it will blur your vision. For those who don't know, the trunk in a crown vic is sealed off from the interior, so i can only imagine how hard it would hit in a car with the seats folded down!

They Smash The Lows

December 23, 2013

These subs are amazing for the money! I have two of these in my Chevy Tahoe powered by a 2400watt rms Hifonics Brutus (Hifonics BRX2400.1D (Brutus BRX-2400.1D)) and they bump really hard. 0 gauge wiring is great for the amp and allows it to really give clean power to the subs and lets them do their job. These subs are very conservative with power so don't be afraid to run them at a high rms. Although they don't hit highs super well (15's aren't ment for that) they destroy the lows and make everything shake! I recommend this sub to anyone who wants some really powerful low hitting bass for a cheap price!

Can't handle big power

March 16, 2015

I would not recommend running this woofer over 1000 watts. Definitely could not handle the 1500 - 3000 watts I gave it. Overall the woofer lasted 2 weeks at a moderate level of bass and I smelled it the whole time. Didn't sound bad when it was playing but there is better woofers for just a few dollars more. I would only recommend this product if you are a non bass freak and you like low level music volume.

October 29, 2013

So I ordered this thing 2 weeks ago, just got the box (A Groundshaker SQL15 from Sonic of course), and the amplifier (A Power Acoustik 4000 watt BAMF).
Upon receiving the sub I was very impressed, Power Acoustik has done big things with this, I even had to shave down the Groundshaker box's opening a bit so the INSANE spider basket would fit!
Onto how it operates....
I have the amp at half the gain for the break in period. It hurts to sit in my car. On higher volumes it will take the breathe out of you. The lows sound so clean it makes my pants wet with joy.

I am honestly scared to see what this thing can do once I crank the amp up. even more terrified once I get a second one and wire it down to 1 ohm.

ALSO forgot to mention, on the side I'm also running two 12" Kicker Comps, nothing special but they definitely compliment the MOFO's mid-range quite nicely.

Install was easy, used a Belva 0 gauge kit; true 0 gauge wire for all of you wondering which wiring kit to get for the cheapest.

Sonic also delivered these things in an extremely timely manner; and for that big ups!

RMS Power and reviews... big magnet, looks good. I must see it and try it for my self...
Mauricio M on Feb 25, 2015
I purchased this because I wanted something to hit the lows hard. I had 2 Sony Xplods 1300 watts a piece which really made up feel the bass but after reading reviews and watching videos I believe this will hit even harder.

I This for one or two?
A shopper on Nov 25, 2014
Best Answer: Not exactly sure what the question is but if you mean the price per sub, it's one. If you r asking about the final impedance for this particular sub it is either 8 or 2. I'm running 2 for a final of one ohm off a polk 1200.d in a very small enclosure, about half recommended and it moves my windshield about an inch and if your not careful on some songs it feels like a gorilla grabbing you by the throat. Recommended product yes, but the posted wattage is a little boastful. Not a huge issue unless your trying to compete and need to put a bunch into it. SQ is good, break them in with respect and they will be just fine. Iv'e had mine for a while and trust me I don't listen to anything low. They do get a little stinky for a bit and can get kinda warm just like any other sub so remember it's a motor and it needs to breath. I know that was a lot of info but take it with like any other review, one man's treasure is another's pile of junk.
