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.
1400 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.
700 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
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).
20 - 200 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".
91 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.
16.25 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.
ABS Plastic
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.
Nitrile Butadiene Rubber (NBR)
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.

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.
1.02 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.
1.02 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.
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.
7-5/8"
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.

BEST OF BOTH WORLDS

December 17, 2010

Its been about 6 weeks since I purchased this woofer from Sonic. I am driving a single SR124dvc in a sealed box at 2 ohms with 900 RMS watts applied.....I believe is fully broken in by now, so here is the scoop.....This woofer really seems to have captured the best of both worlds...good SPL and really fantastic SQL...plays deep and has plenty of excursion for high volumes etc....highly recommend to anyone looking for good all around sound. Be sure to apply plenty of clean power for best results!

Solid Woofer

January 3, 2011

This woofer has a high thermal power handling (700w RMS) for those who want to "bump" for hours on end. It sounds as good as any woofer in its price range and even higher. However, the biggest cons are (1) the price (if you are shopping for your first woofer, you may not fully appreciate this at first and I'd go with something a little cheaper) and (2) Xmax of 16mm is adequate but a little more would be nice.

This obviously is a GREAT looking woofer, very classy and beats out all the other major brands as far as aesthetics are concerned. Even if you inverse-mount it, the motor looks incredibly nice. It's almost a shame that it's hidden inside the box of most installs.

As far as putting it in an enclosure... This has a relatively high QTS of .55 (if you are not familiar, you probably want to do a little research before you invest in a nice subwoofer). This means that it is best suited for large SEALED enclosures. You can still put in in a ported box, but make sure you hire a box designer with modeling software, or it might turn out to sound like poop. But yeah, this sub likes LARGE sealed boxes (at least 1.5 cubes but upwards ot 3 cubic feet would actually be ideal) despite what the manual tells you. I was also annoyed by the manual that it didn't list the driver's average estimated inductance.

Bottom Line: if you are looking for a quality driver that can handle the heat, looks great, built by a reputable company look no further. Just make sure you have the cargo space for a large box.

Accurate, detailed bass

February 21, 2010

I've had mine about a week now and it's not broken in yet but I can tell a difference every day in the sound. Unfortunately I don't have a really strong amp yet, but on 250rms this thing still does plenty of work. It has tight sound and can hit as low as any other sub I've heard. Once I get a T1000-bd from Sonic I'll be able to see it's full potential. I highly recommend this product but they are slightly hard to come by here if you want the DVC model. Sonic has THE BEST price I could find anywhere.

I just put this sub into my truck. I have a single cab truck with a wedge sealed box, the volume is around 0.75 cubic feet. The sub hits clean, crisp & hard. Plays well with all types of bass, not just low but higher tones. I listen to a lot of rock & a lot of rap. After owning MTX, Audiobahn & MA Audio subwoofers, I'm now a Polk Audio fan, this sub kills any other 12" Sub I have ever owned!

Kicked in the back

December 22, 2006

A Truely unbeatable subwoofer for SQ and incredible SPL to boot! I have used JL W6's, Alpine Type X's and eD subs and non of them have anything on this new sub line from Polk. They sound as beautiful as they look. Its almost a shame to hide the beautiful motor inside the enclosure. NICE NICE work Polk - finally a manufactue who cares more about sound quality than SPL's or slick BS to push their products.
2 12's is in a E46 BMW - its like being kicked in the back and its a sealed rear seat!!! Imagine these is a hatchback.

October 20, 2006

I have this in a '05 Altima hooked up to an Alpine 600RMS amp (ported 2 cubic ft enclosure). My rearview mirror fell off!!

This sub hits almost every bass note and when it hits low....holy shiznat! I keep my amp at half power but when I turn it to 80%, it feels like my car could fall apart at any time.

Not only does it hit hard, it hits very, very clean. If you're willing to spend the money, you'll be amazed.

This is definetly a nice clean, deep, low sounding sub. I have one 12 in my car and it pounds. I recomend this sub too anyone that wants a good hard hitting sub that doesn't have to put a lot of money into there system. I spent about 1100 on my system and I can't be anymore happier. This sub actually makes people think I have 2 or 3 subs. I have an alpine v12 600 watt amp pushing it. the amp is only halfway up and I'm flexing the hell out of my front winshield.

Impressive SQ and SPL all in one sub!!!

April 16, 2010

I was in the market to buy some new subs for my vehicle. I have previously ran Type Rs, CVRs, L7s, P3s, W3s, W6s, you name it. Ive tried them. So this time around I wanted something new. I heard 2 of these in a vented box at a shop in my area. I was sold. I ordered 3 from sonic and put them in a 4.5cu.ft. sealed box. This subs hit EVERY bass note you can imagine and then some, AND its sounds crystal clear while doing it. I would probably label this sub as a SQL sub because is it does hit hard and low, yet maintains its SQ precision, even at LOUD volumes. I recommend to anyone who wants quality bass. Just make sure your mids and highs can keep up...
