Loud Bass with a Low Price

If you are looking for the most bang for your buck, the Kenwood KFC-W3012 has got you covered. This 12” round subwoofer delivers 400 watts of RMS power and a max rating of 1200 watts. The polypropylene cone woofer ensures tight bass, while the urethane foam surround facilitates peak excursion and provides added durability for better bass performance. The double-stacked magnet is used to create a linear motor with enhanced peak excursion for optimum bass output. The dragon spider design enables the center of the subwoofer to withstand more stress when being played. These subs will produce a deep bass sound and the extended excursion will allow the subwoofer to handle low frequencies without ruining the cone.

This particular subwoofer has spring post terminal assembly that will accept up to 8 Gauge wire, making it easy to connect to an amplifier. Be sure to find an amplifier that can provide enough power to the sub because it is a single voice coil sub that will run at a 4 ohm load. The sound clarity is amazing and since Kenwood doesn’t skimp on looks or quality, you know you will be getting a valuable product.

In order to get the most out of your new subwoofer, we recommended getting a sealed or ported box. For sealed box, you will want to stay in the range of .75 – 1.75 cubic feet to get the most out of your sub. For a ported box, stay in the range of 1.0 – 2.0 cubic feet. A box is necessary if you want your subwoofer to last and perform at its peak ability. Don’t worry if there isn’t enough space in your vehicle! The KFC-W3012 was designed with a shallow mounting depth for easy installation.

Subwoofer Specifications

Subwoofer Series
Each subwoofer manufactured is part of a series. This is the name of the subwoofer's series.
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.
1200 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.
400 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.
Single
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
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).
39 - 300 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".
86 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.
13.8 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.
Dark Gray
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.
Polypropylene
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.
Urethane
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.
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.
.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.
1.75 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.
1.0 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.
2.0 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.
6-1/4"
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.

February 13, 2011

I bought two of these subs and put them in a sealed box built to the specs given with the subs. I ran a RFL600D to these subs producing 600 RMS at 2 ohms to these subs. They HIT hard. Unfortunately one of the subs "fried". It was hard to explain but a month after install one of the subs started sounding funny so I unhooked the speakers then hooked them back up and one of the subs was permanently altered. The sub sounds OKAY in a box by itself but once i wire it up with another one..it sounds horrible. Good buy though and great performance

March 31, 2011

My friend bought two of these hooked to a Kenwood 1800 watt amp. These subs are not even close to hitting 1200 watt. Maybe they hit 400, but they dont sound like it. My two Kicker comps hit harder than these with a 600 watt amp. 6 months later the Kenwood sub spider ripped off of the cone. Good sub, for a while, they don't bump.

January 20, 2011

I have one of these in my basement. I connected it to a Lanzar Max 224 (1000w) amp and it Pounds!! if you think a cheep amp like Lanzar is not good quality, IT IS!! I couldn"t ask for a better amp for the price! If your wondering how to power a car amp in your house its REALLY EASY!!.. You need to get a PC power suply ($5) and search on Youtube: how to hook up car amp in home. theres tons of videos.

This sub is awesome, I purchased for $65 back when it was available for that price, but either way this sub bumps, I has great sound, gets nice and low, it hits a lot of different notes. I have it hooked up to my 1000Watt kenwood amp, and its a great combination. I would Highly recommend this sub to anyone!

This is a great sub and sounds so good in my Ford explorer. I only have one because of my limited budget, but wow that's all I need!! It impresses everyone that gets in my truck. You have to tweak some settings on your amp and head unit but after that they're ready to pound!! I would absolutely recommend these to anybody!! They do a great job of producing solid bass.

I bought this sub awhile back to uprgrade from a 12" Sony explode. It's a decent sub, especially for the price you can't go wrong. Don't expect too much bump out of it. If your just looking for a good, clean , tight bass, this is a good starter sub for you. I didnt keep it very long, so im not sure on the durability of the sub, but as with any cheaper sub, dont try to over power it and you should be happy with your purchase. I would personally recommend always getting a dual voice coil sub opposed to the single just for my wiring options.

Great subs.

October 10, 2010

These subs hit very hard for the price. I have them running off of a Kole Audio amp. These have a great sound quality and I would definitely recommend for anyone looking for added bass on a budget. They have been very good with no problems in over a month of use. They don't seem to be very much quieter than a more expensive sub to me.
