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.
10"
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).
25 - 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".
87 dB
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.
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.
Butyl 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.
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.
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.
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.
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"
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.
9"
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.

Polk Audio SR104-DVC

March 28, 2011

I have two of these Polk Audio SR104-DVC , i have a Precision Power DCX 500.2 amp pushing both of these and they do the job and then some :) Any one who planes to run Polk all the way around these SR104-DVC are closers end of story, my head unit is a Alpine 9887 with lots of options for tuning, I have another Precision Power Amp DCX 300.4 pushing the component Polk Audio db5251, along with Polk Audio 6x9's db691. I have one 2 Farad cap for the 4 channel that keep the power stable one the four speakers.
I plan to upgrade all speakers to SR from Polk but at the costs it hard to get a handle. I love this site www.sonicelectronix.com I wish I new about it sooner I cane across it one day looking for these bad boys SR104-DVC.
The SR104-DVC are not cheap but worth every penny.
Ps you do have to brake these in a little bit, if you dont you will smell the sub getting hot.

Big boom!

April 14, 2009

I originally purchased these speakers to be an upgrade from my MB Quart subs mostly for their power handeling. I have always been a fan of Polk speakers so I figured they would be comparable in sound. Boy was I wrong! The accurate reproduction of lower frequencies from this monster totally dominated the poor MB Quarts I was running. Don't get me wrong, the Quarts still sound great, but they can't hold a candle to these!

The only drawback to this speaker is the large basket design. It was too large for my enclosure so I had to mount the sub inverted. While this takes up more room, I get to show off the nice chrome basket! If you are thinking of getting a serious speaker, then look no further!

JUST BUY IT!!!!

June 30, 2011

So, I must have looked at this thing 100 times in a month before going ahead and ordering it. I have a custom fiberglass enclosure that's a little more than 1 cubic ft and I'm using the Polk PA1100.5 5-channel amp powering my whole system. My original sub was just a plain Jane 4 ohm single VC Kicker and it sounded pretty good. I was really just shopping for a dual voice coil replacement so that I could run my amp down to 2 ohms. I went back an forth and eventually said to heck with it and spent the extra money for this sub mostly based on the reviews I read on Sonic and elsewhere. IT'S ALL TRUE! This thing is amazing! It does have a much higher SPL than the Kicker I replaced, but really stands out is the sound quality. As with the other reviews on here, the kick drums sound like kick drums (imagine that). If you're serious about audio and want your sub to reproduce music and not just a bass sound, but this sub. Follow the directions, however. They state that a break in period of 50 hours is required before it will hit it's stride and it is true. The surround on this thing was so stiff that you could hardly even move the cone with your hand. I noticed an improvement in SQ just after the first hour. Given the large volume displacement of the RIDICULOUSLY sized basket on this thing I figure that it's sitting in about .8 cubic ft of airspace which is about .16 more than recommended, but it sounds AWESOME! The quickness of response with this thing really stand out and it handles overlapping freqs with ease!

PROS - Fit/finish, SQ, value, looks, quality (it's worth way more than this price tag!). This may be the most musical sub I have ever heard, period!

CONS - it is heavy! Make sure you have a sturdy enclosure and bolt it to the car for the best result. If you're a teen aged kid with a box sliding around in your trunk, buy the cheap Kicker or equivalent. This sub deserves a well balanced system in support of it. Also, I wouldn't mount it to your baffle with Dry Wall screws, they won;t stand a chance. Get yourself some t-nuts so that you can really tighten it down snug!

I totally recommend this sub to anyone. It is well worth twice this price! Don't be cheap, just buy it, but don;t disrespect it by only playing rap or hip-hop through it. This thing really deserves to be listened to.

Polk Audio SR104 DVC

January 4, 2011

I think this is a Very Amazing that is deep and clear and so do my friends that have 1) a 12" Type R and 2) a 15" kicker. I put 800 watts rms to it and wish I had 1000-1200 rms going to it. It doesn't skip any notes and hits a few more lower ones. I have it in a custom ported box set to spec. If you do get one of these it doesn't rock the block but the car next to you can definitely hear it.

Excellent Sub!

February 25, 2010

The Polk 10" SR sub is outstanding, well worth the money.
Its one of the cleanest tightest subs I have ever heard. not great where limited space is a concern but I have it in a 1 cu. foot sealed box with a 500W Kenwood amp an its amazing.

by far the Best component of my car audio!!

October 19, 2009

This subwoofer performs far beyond any 10'' i have heard. In a sealed box it creates such distinct tones, kick drums sound like kick drums and thumping deep bass is not loose and wallowy but tight and direct. i love this sub! To all the reviewers claiming it distorts at high volume u might want to use a better amp cause its not the sub ;)

Very loud, quick bass response

June 16, 2009

I would recommend these subs to anyone looking for a high end sub, but remember they require alot of power to get the best performance. You won't believe how heavy they are until you pick 1 up, huge magnet, make sure you get the dual voice coil, there is a big difference in performance.

Awesome sound quality in a small package!

June 25, 2009

I purchased this sub from Sonic Electronix approximately six months ago and since have loved every minute of it. I have it matched to a 500.1 Carbon Series Polk amplifier and it hits hard but clear.

This is currently installed in a small, .90cu.ft. enclosure, which is near what this speaker is designed for.

Its design is durable and forgiving, and its aesthetics are subtle for any interior giving your setup an OEM look.

The King of Subs

July 12, 2007

Wow, this is one good-looking, clean-sounding sub! I hear detail with this sub that escaped my Infinity Kappa Perfect 10.1. By far the best sub I've ever owned, this has the spectacular quality and plenty of power. One look at the back of this sub and you'll know they paid attention to every detail and took pride in their workmanship. This is my first Polk sub, and I am now a convert. Great value -- highly recommended!
