Subwoofer Specifications

Subwoofer Series
Each subwoofer manufactured is part of a series. This is the name of the subwoofer's series.
db (Polk)
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.
540 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.
270 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).
28 - 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".
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.
7.5 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.
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.
Santoprene 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.
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.
0.66 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.
0.66 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.
1.25 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.
1.25 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.
5-7/16"
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.
9-1/16"
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.

Great sound in sealed double enclosure

October 20, 2014

Although I've spent limited time listening to the system in my boat cabin (where the Polks reside), so far I'm happy with the sound. They're installed in a dual sealed enclosure (I think 0.7cuft per driver) and they are driven by the 5th channel on a Cadence F100-5 amp and complementing four MB Quart PVL216 6.5" full-range component speakers (which I really like). I'm much happier with the "neutrality" and accuracy of this setup as compared to a single 10" sub in a vented enclosure, which was boomier and had obvious peaks at certain frequencies that obviously colored the music (rather than just reproducing it). The Polks are tight and play every frequency evenly (I listen mostly to 70s/80s rock, fusion and prog). I have not tried any other subs in this enclosure so I can't compare them to another brand or style, but I would definitely buy them if I had to do it over again.

Love em

January 9, 2014

Have 2 of these in a sealed box running 250RMS to each of them. They are clear and have plenty of low end. When I first got them I was like eh.....I could use a little more output because I'm used to my JL 12w3v3 but once they broke in they really took off and play all types of music great and get LOUD. Tight on rock (feel it in my chest), boom on hip hop/rap (shakes the whole interior). I recommend them to everyone that is looking for an amazing budget sub. I still like my JL's a little more but they are bigger and get more power and cost $200 more. Better than the Power Bass 10's I had though.

db1040 Subwoofer

September 10, 2013

I was originally skeptical about this sub due to the low cost and low wattage ratings, but after having this sub for about six months, (and after having been broken in), I am definitely very happy that I purchased it. It doesn't pack as much punch as some other subs that I have owned (Alpine's, JL's) but those were also higher powered and in specific boxes designed for them. This sub is very clean sounding and adds a great low end to your music. I would recommend using a 600 RMS or higher amp however, the amp that I am using is 400 max (about 185 @ 4 Ohms), and it is definitely under powered so I can't crank the volume for fear of clipping.

For "normal" listening tastes

August 5, 2013

The db1040 works perfectly to fill in the bass on normal full range music. I have this powered by the sub out of a Polk 5CH amp that is also powering my 2 sets of Focal 5.25" coaxials. The blend of the bass from the db1040 and the other speakers provide a nice and "full" listening experience in my vw camper van.

Just as hoped for

August 5, 2013

The Polk db1040 is just the ticket. It powers my 2 sets of Focal 5.25" coaxials and a 10" Polk sub thru an Alpine head unit. I have very good dynamic range and no distortion at levels that can go way louder than I will ever need.

I like the remote (wired) subwoofer level control to adjust for the varying EQ on my music.

An older Alpine 5 ch amp I have in another car tends to overheat and cut out. I've never had that happen in the 6 months of use since I installed the Polk. I'm very satisfied.

Provides the Missing Bass

August 30, 2011

This sub works great. Previously, my '02 LeSabre had nice sound with a Clarion head unit driving Sony ExPlode speakers in the door and back. I purchased this sub, an enclosure with a Jensen amp recommended by the excellent phone hostess. Within a week I had it professionally installed and I tuned the bass to fill in what was missing. It provides oomph and subtle warmth. when cranked, it performs admirably without cracking. A track on Neil Young's Lenoise album literally rattles my teeth. I highly recommend this sub and the matching Jensen amp.

ear hurting bass!!!!!

June 18, 2010

I just got 2 of these bad boys and woah. they are only hooked up at 4ohms getting 300watts, and they are twice as loud as my 2 comp MA audios that were getting 500watts each at 1ohm and I only have my amp at a 1/4 gain for the break in period and my can hear me coming from about a mile away and there is no looking out the rear view mirror cause it rattles so much. There is absolutely no cons to this sub all pros. So if your tight on cash they are the sub for you
