It's Called PUNCH For A Reason

The coldest blood runs through the veins of this Rockford Fosgate subwoofer. The 12" dual 2 ohms Punch Stage 3 subwoofer gives the cold shoulder to mercy when it comes to window rattling bass and clarity. The 2.5" dual voice coil receives its power from double stacked ferrite magnets throwing around 1,000 watts of peak power in your face. These energy thirsty Punch stage 3 subwoofers have a simple request; to receive lots of power. Their Kevlar fiber semi-pressed paper cones combine light weight with high strength to dramatically improve performance. Compressed sealed high excursion Poly-ether-ester makes up this woofers surround providing a strong yet elastic connection to the cone. To keep this beast cold blooded, Rockford Fosgate uses anodized aluminum voice coil formers to provide excellent heat dissipation. This punch woofer has stitched tinsel leads that withstand extreme duty cycles, fatigue and high current that is critical to its robust design. This 12" dual 2 ohms Punch Stage 3 subwoofer gives no mercy when it comes to performance, power handling, and construction quality. Just listen, and you will understand why its called a Punch!

Subwoofer Specifications

Subwoofer Series
Each subwoofer manufactured is part of a series. This is the name of the subwoofer's series.
Punch P3 (Rockford Fosgate)
Subwoofer Size
Refers to the diameter of the subwoofer, measured in inches.
12"
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.
1000 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.
500 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.
2 ohms
Voice Coil Diameter
Diameter of voice coil, usually measured in inches.
Frequency Response
The range of frequencies the speaker will reproduce (lowest frequency to the highest). Bigger is better, meaning the wider the range, the better. The optimal range is 20 - 20,000 Hz (which is the range of human hearing).
27 - 250 Hz
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".
84 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.
16-3/16 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
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.
Kevlar Fiber
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.
Poly-Ether-Ester
Magnet Structure
Defines the overall structure of the subwoofers magnet.
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.
Optional (Accessory required and sold separately)
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.
.75 cubic feet
Optimum Sealed Box Volume
This value indicates the ideal sealed box volume that the manufacturer recommends for the subwoofer. The volume is typically displayed in 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.
1.25 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.
1.79 cubic feet
Optimum Ported Box Volume
This value indicates the ideal ported box volume that the manufacturer recommends for the subwoofer. The volume is typically displayed in 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.
1.79 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.
6-3/4"
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.
11-1/4"
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.

No

Electromechanical Parameters

Free-Air Resonance (Fs)
The free-air resonance frequency of the subwoofer, measured in Hz. At this frequency the weight of the moving parts is perfectly balanced with the subwoofers suspension system.
Equivalent Compliance (Vas)
This is the amount of air that has the same stiffness as the subwoofers suspension. The greater the rating, the lower the stiffness and larger recommended enclosure. It is measured in Liters.
Total Speaker Q Value (Qts)
This is the subwoofers relative damping (Q) at the resonance frequency (Fs), including all dimensionless losses. Essentially, a high Qts value (closer to 1.0) means the subwoofer is great for sealed enclosures and a low Qts value (closer to 0) means the woofer is great in vented enclosures. A Qts of around 0.45 means the woofer will work decently in either enclosure type.
Electrical Q Value (Qes)
The subwoofers relative damping (Q) at the resonance frequency (Fs), including electrical losses. Also called the mechanical damping of the subwoofer. The unitless measurement usually varies from 0.5 – 10.
Electrical Resistance of Voice Coil (Re)
Amount of DC resistance of the subwoofer when measured with an ohm meter. Typically, this will read less than the impedance rating of the subwoofer.
Mechanical Q Value (Qms)
This is the subwoofers relative damping (Q) at the resonance frequency (Fs), including mechanical losses. Also called the mechanical damping of the subwoofer. This unitless measurement usually varies from 0.5 – 10.
Efficiency Bandwidth Product (EBP)
This number represents the trade off between having an efficient woofer and one with a wide bandwidth. To calculate this number, take the Fs and divide it by the Qes. If the number is below 50, the woofer is designed for a sealed enclosure only. If it's between 50-100 it can be used in either. Lastly, if it's greater than 100 it's designed for vented enclosures.

I can't believe they're only $150 now!!!

September 7, 2011

I have owned 2 of these subs in a ported box now for 3 years. And they still suprise me with how loud they get. These subwoofers have already killed one amp and now are running connected to a 1700 watt monoblock Hifonics (wired at 2 ohms for 1200 watts RMS) and they hit HARDER than ANYONE in my town. Everyone that has a system and gets in my car can't believe it they always say "How are you hitting harder than me!?!??" I am a diehard Rockford Fosgate fan now they sound better then any sub and hit soooo hard. REMEMBER rockford fosgate subs RMS are rated on how many watts it can handle for a FULL 24 HOURS. You could bump this at 6-700 watts for hours and it wouldn't even break a sweat

April 11, 2011

This is so bang for your buck you won't even know what hit you when your teeth are chattering and you can barely hold onto the steering wheel. Get this thing ported in about 1.7 cubit feet and it will hit every note up to the highs and down to the lows. I love this subwoofer. I have always loved Rockford Fosgate but this time they really showed me what they are worth. I honestly dont think I can blow it, I seriously tried and I'm using a T-1500 to push it. Screw all those 500 dollar sub woofers SCREW IT!! I'm telling you this will not let you down if you love metal, rock, some hip hop, rap, dubstep. Everyone that walks into my car LOVES it. Its good for bumping and just getting a full sound out of your audio system.

September 16, 2010

I bought this sub 6 months ago and have loved it ever since i installed it. After 5 months of using it i realized it was not properly amped and i was providing half of the power it deserved and even so it still sounded great! I can only imagine what it would sound like when i give it its proper wattage. Also i had it in two cars, the first car i totaled and it was in the trunk during the accident and it is still in perfect working order, so its very durable indeed! Haha

Hell Yes!

August 18, 2010

These subs are terrific. Granted I have them in a box that was originally built for 2 P1s (modified slightly to fit these beasts), these things pound so hard. Have em hooked up to a 1000 watt amp, and it does the job just fine. OH, and delivery? Amazing. Standard shipping is supposed to take 6 days, but these puppies were delivered to my door within three days of me placing the order. So don't waste your money on different shipping plans. Just do standard, you won't regret it. Overall, I couldn't be happier. I plan on buying one more because I have a three hole sub box sitting in my garage, though one of these is plenty!

I bought this to replace a pioneer shallow mount that had blown. At first I was mad about having to replace it but once I built the box and hooked this thing up I was happy. This sub is just like any other Rockford product, flawless. Like every other product produced by Rockford this sub woofer can handle more then its rated at. The sound quality is fantastic, lows and highs hit hard. One 12 is plenty, my car looks like its having a seizure when I turn the bass all the way up. I know if you order this product you will be happy with your purchase.

I currently own two Rockford Fosgate p3d212's and I plan to buy one more. I've always liked Rockford because they make good quality subs that can handle extreme bass under any type of conditions. They are reasonably priced for those who are ballin on a budget! If you want to bang better than the rest choose Rockford Fosgate, and you'll be shutting down the competition!!

Great Subwoofer!!!!!!

March 5, 2010

If your trying to beat down the block than this is the sub for you just make sure you get the right size box and feed it at least 500 watts RMS to get the full potential out of this subwoofer. And to all you people out there that think its good to under power your subs your wrong its actually bad for them and they wont function properly.
