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).
25 - 800 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".
90 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.
11.3 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.
Stainless Steel-Coated 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.
Rubber
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.
.8 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.
6-11/16"
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"
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.

Good sub

September 19, 2009

The sound is fine, the only complaint I have is that the dust cover is pretty fragile. I dropped the screw driver on it from about 6 inches and it put a two inch long crack in it. It still sounds fine though. It looks really cool.

Really good

September 7, 2009

It was a really good sub. i only had about 100 watts running to it cause i had a small amp. but it still shook my 89 honda civic pretty good. It was in a sealed sub box that i made it sounded really good. i had no problems with it. i really want a second one.

Going Strong

June 3, 2009

Bought this set up approx. 6 months ago; a set of Kenwood KFC-W3011subs,Sonic Sub Box 2SV12-GRAY, and a Kenwood KAC-7204 amp. Everything is still going strong. A good strong amp and subs for the price. The box is well built and sounds good.

Great subwoofers.

May 6, 2009

These subs are great. i bought them off my friend for 50$ i have 2 in a non ported box and they still pound hard in the trunk of my accord. i have them hooked up to an 800 watt 2 channel sony amp and they're great.
btw the amp only puts out 200 watts rms to each and they still pound.
Great subs for the money. if i needed to i would get them again their a steal!

August 2, 2009

i bought 4 of these subs from sonic electronix and their prices were unbelievable these subs pound hard enough to turn heads and they are hella clean sounding. dont expect to be in any competition with these beginer subs but you will be supprised. thety handle alot of rms power (400) . the thing that knda does suck is that its a svc not a dvc. bt for the price you realy cant complain. i was setting off alams with these in my durango. and two 1800W amps.

June 10, 2009

I blew my Alpine on my Kenwood amp...so I decided to try this product. I was not surprised. For the price and performance I have not had any problems. It works where the Alpine with the same ohms and watts did not. Im very, very pleased.

Budget Build

April 27, 2009

I own 2 of these, they are powered by a Hifonics BXi1606D. Each sub sees 2.25 cubes after displacement tuned to 36HZ, Subs are good if your on a budget. They pound at 60HZ, but anything below ~45HZ they are lacking. Subs are extremely stiff and are power Hungary. I can not emphasize enough on STIFF!
i was originally powering them off my ZX400.1 which is rated at 450wrms at 2ohms and it wasnt enough.
They now see 1100wrms from my BXi1606D which livened them up alot but the lows just arent there.

wow

March 8, 2009

Wow. I have two of these in a 2.0 cubic foot box in the back of my 97 ranger and it slams. I never would have thought that these subs would sound so good for the price but boy was i wrong. I\'m about to order my third one and put into a custom box and get a bigger amp because now i only have an old phoenix gold amp my uncle found and its putting about 300 rms to each sub. I would highly recommend getting these subs to anyone, whether you have money or not this sub is a steal.
By the way, my friend has 2 kicker 15\" comps in a 5 cubic foot box powered by a kicked zx550 and these are louder and he paid over twice as much as i did.

Great Buy

March 3, 2009

Wow where to begin?

Value: they hit so hard. Big name, good looks, 400wrms rating, good sized magnet, great sound, what more could you want for your money.

Look/Design: Some what plain, but yet classy. No complaints.

Durability: Still breaking in, but soo far durability isn't an issue. Appears to be well made, expected from a big name company such as Kenwood.

Features: Single 4ohm works for me. Not sure what other features you're looking for.

Ease of Use: Comes with good instructions and every thing needed to get mounted.

Overall: Very satisfied. I'm running one of these hooked up to a Dual amp putting out 300rms in a Kia Sportage and it sounds great. Hits much harder and much louder than I expected. A friend of mine had dreams of putting 3 12's or 2 15's in his Cuttie, but after hearing how loud this sub was at only 75% of the rms rating, he plans on picking up just two of these and a nice amp.

Don't have any doubt when buying theses subs.

THIS THING BANGS FOR THE PRICE

December 31, 2008

ONE OF MY FRIENDS GOT A PAIR OF THESE OFF OF SONIC ELECTRONIX. WE HOOKED THEM UP TO A 2400WATT AMP AND PUT THEM IN A SMALL SEALED BOX BOY DID THEY BANG. THEY HAVE REALLY GOOD SOUND QUALITY IF THAT IS WHAT YOU WANT. BUT WITHIN A SECOND OF TURING THEM UP HE MADE HIS REVIEW MIRROR DROP. I MEAN THEY SOUND GOOD AND RICH; YOU WON'T REGRET BUYING. ONE OF MY OTHER FRIENDS EVEN GOT A PAIR FROM SONIC AFTER SEEING WHAT THEY CAN DO. THEN HE HOOKED THEM UP TO A 2000 WATT AMP AND IT IS BANGING. I WOULD SAY THEY CAN HANDLE MORE THEN THEIR RMS.
