Subwoofer Specifications

Subwoofer Series
Each subwoofer manufactured is part of a series. This is the name of the subwoofer's series.
Shallow Mount (Pioneer)
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.
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.
300 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.
2 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 - 290 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.
5.5 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.
Interlaced Carbon-Glass Fiber Composite (IMPP)
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.
Fiber Woven Radial
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.
0.35 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.
0.7 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.
0.35 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.
0.7 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.
3"
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.
9-5/16"
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.

Yes

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.

sub is ok

January 23, 2011

First off this sub sounds good but do not play rap with it. Thing bottoms out like crazy with the bass boost off and gain of my amp at 1/4. powered it with a Kicker ZX.300 so it defenantly couldnt handle 300rms due to the fact that it blew in one month and for that entire month all that could be smelled was voice coils burning. Dont waste the money and go with something else. I would recommend Kicker or rockford fosgate. Got so sick of the shallow mounts I just said forget it and threw two twelves with 2,000 watts in the back seat. Now thats what i call bass. These shallow mounts sounded like little 6x9s beside what I have now

Better than expected shallow mount subwoofer

October 28, 2012

I have used/ran many different subwoofers for over 15 years now - most recently I conducted a test of a small sampling of different subwoofers a couple years ago (Boston Acoustics G2, Cerwin Vega Vmax, Alphasonik 400-Series, Pioneer TS standard). The Pioneer in that study did OK (not the best, but far from the worst, so I decided to give the Pioneer a shot when I was in the market for a shallow mount for installation in a Mistubishi Raider/Dodge Dakota quad cab (I also purchased a MB quart shallow mount 10 which fried during break-in...still plan to test eventually). This sub met my goal in terms of mounting depth and enclosure recommendations/requirements. I was a little concerned going into it about the frequency response of the sub (Fs is around 40 Hz).

First impression, the sub is relatively sturdy - noticeably heavier than the MB Quart and the basket is well built. Overall construction is pretty good - no excess glue was visible on the cone and it looks relatively clean. I broke the sub in with a 45 Hz test tone at about 50% capacity (free-air) ran for about 30 minutes. The enclosure I ended up with is about 0.45 ft^3 (sealed), with about a 8 oz of poly fill. I typically prefer the output and performance of a ported system but lack the space in this application. I first tested this indoors and then in the vehicle (installed directly behind the back seat of the drivers side of the cab). Indoors, it provided decent OK low frequency response, with lower tones getting muddier and less impactful (as expected - sub 35 Hz type tones). In vehicle, the frequency response drop-off was less noticeable, and played as well as some larger non-shallow configurations. For a single 10, it plays very well - better than I anticipated from a frequency response and output perspective. Based on my prior experience, I would argue that it plays as well as a lot of entry-level single sub systems - if you did not know it was a shallow mount, you probably would not be able to tell based on how it plays. It's relatively quiet in terms of cone noise and has very good impact on rock tunes. It's slightly muddier on extended note rap music (but, it doesn't detract very much from the music - it's better than a lot of subs I have heard and may be related to the amp that I have chosen for this setup and it's poorer dampening factor). It's power requirements aren't crazy high, and in the 2 ohm config, you can use a smaller class D and be able to easily power it (for not very much). I'm overall very pleased with this sub. The MB quart (while working) seemed to go a little lower (indoors) but was not as 'loud' (i.e., efficient) as the Pioneer. I may still test it at some point in time, but right now this is fulfilling what I wanted it to do. My only complaint with the sub is it's overall mounting thickness is higher than I would like, which will require some cushion modifications to accomodate the box/sub (it's got a pretty thick mounting flange/gasket - this seems to be something that Pioneer has moved to in recent years). It's about 6 mm thicker than most other gaskets.

If you're looking to add bass and have limited space constraints, this is a pretty good option given the cost/value. I think you'll be hardpressed to find something with this overall thickness with this capability (I think you'd end up having to jump up to the $180 range to start seeing significant differences - given the overall thickness of the sub). Some of the 'thicker' shallow mounts may be a little better, but in my opinion, they are not really shallow mount subwoofers if the enclosure size requirement starts to creep up to the 0.7 range (for a 10). If you can give up the space, obviously this sub is not going to outperform every "thick" sub in this price range, but it will perform as well as quite a few in this price range given a sealed box.

awsome sound

December 20, 2012

I had these in the back of a 92 Camaro with a m.a. audio 400 watt amp which is under powering them by far and the hit very hard but of course if u know anything about cars...its not hard to make a Camaro sound awesome....but the rear veiw mirror fell off quick n they never fizzled out on low low bass they took the abuse....but now iv took these subs out n going to put in either two 12in mtx terminators or two 12in kicker l7's with a kicker 2500.1 amp.......im putting the pioneers in the back of a 98 chevy ext cab pickup just orderd the box so ill post a review 1nc i wire them up! highly recommend these for 1st time sub buyers n the only bad thing is they wont fit ina normal 10inch box which igues is a good thing oh and these subs are still tight n i hammered them they are still nt evan broke in and i abused them a bunch!!! but they still feel n look like they came out of the box.....if u want a good sub or two for alittle money go with these u wont be dissapointed......

Good Sub

November 9, 2012

I bought two of these and installed them into an under-the-seat down-firing sealed box in a Silverado 4 door pickup. These were to supplement the two sealed kicker comps that I have behind the seat. They outperform the kickers and add the extra "boom" I was looking for. I have them hooked up to an Alpine PDX-6 amp.

The only issue is that you have to trim the opening on standard boxes to fit the subs. They are about 1/4" larger in diameter than the opening. So keep that in mind.

These subs are a great product. The sound quality is great and the design of them makes them fit into places that you cannot get regular subs into. The product was exactly as it was described and after 6 months of owning and using them I am very happy with the performance of them. I am running them with a small Kenwood amp and they hit hard and work perfectly. I would recommend these subs to anyone trying to put subs into a small single cab truck or anywhere that you cannot get a regular sub.

August 8, 2012

I bought these subs for my car but had not gotten a chance to install them when my friend blew out the surrounds on his. His boxes are only about .25 cubic feet but these pioneers are still deeper and louder than many 12s I've heard.

great stealthy sub

August 2, 2012

this is a great shallow mount that puts out strong bass. I have it mounted under the trunk floor in a custom box, so it takes up zero usable space in my car. I mostly listen to dubstep and my wife likes the top 40 stuff, and it handles both really well. I've never felt that it was not pushing hard enough. I think it produces surprisingly deep notes for how thin it is. Overall I'm very impressed and would recommend this to anyone looking for a sub but is tight on space.

I've had this in my GTI for 4 months now in my custom under floor enclosure in my trunk. It has enough power to rattle my car but I mostly have it there to fill the void in my stock system. For the price it met what I was looking at spending, it fit where I needed to have it placed. I have it hooked up with a Pioneer AVH P4300 and Alpine MRP 500.

Exceeds expectations

September 20, 2011

I wanted the smallest available option yet ive my bass some hit in my GMC Canyon. I built a shallow box and put behind my seat, but it has so much hit, that the passengers think its behind their seat. Make sure you make a strong box. I skimped on the screws and broke the joint and picked up a vibration after a month or two. As i said, I just wanted to feel some bass but I never imagined a single 10" would do so well. I'm extremely happy and would defintely recommend. P.S. I paired it with a rockford fosgate 300 W punch amp.

This is by far one of the best sub woofers I have worked with. It's very forgiving on the enclosure and produces nice low bass and still remains punchy up to about 250-300hz.
