Subwoofer Specifications

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.
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.
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 - 220 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".
94 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.
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.
Injection Molded Polypropylene (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.
Elastic Polymer
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.

Bandpass
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.
0.85 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.
1.25 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.
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"
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.
11-1/8"
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.

October 3, 2011

first off i fell in love with pioneer sub woofers back in 2008. I started with a 12" w307d4. It pounded. Then i had two 12" w308d4 they pounded. Now i hav the two 12" w309d4. Man the pound i have them hooked up to a hfi hifonics 1000D amp wired down to one ohm. I can be heard frm a block away, when i pull in gas stations i shake their store. i would reconmend getin a 3/4 mdf box though for better sound, up to a month ago i had a 1/2 mdf box and it sounded great for a while but after a few months i noticed my screws was half way out my 1/2 box from bangin so hard. So now i hav a 3/4 mdf box and its even louder. Would reconmend this sub for every one you cant go wrong. Wnd dont do like i did by buyin a crappy box buy a good sub box for these awsume subs. you wont be disapointed.

Great Subs!!!

December 21, 2012

I've owned these subs for about 7 months now and i must say they are great. They are preety powerful with the right amp. I have a 2000 watt amp hooked up to them and the speakers are bridged and man do they hit hard. I been dealing with pioneer for as long as i can remember and these are the best pioneer subs i have ever owned.

December 30, 2012

I have two of these wired to 1 ohm each and I am running a Hifonics 1500 watt amp and they are in there own boxes and they are sealed and they are only .9 cubic feet each but they do the lows great and the highs are great as well. They make ur ears hurt and the best part is the fit behind my seats in my single cab s10. I would recommend them to every one and they aren't beginner subs.

Best Choice

September 8, 2012

Let me first say how impressed i am with these speakers i have three of them powered by a hifonics 1700 watt and when i tell you that people hear me before they see me. Not only are they loud but its a deep quality sounding bass i am going to be honest i wanted rockford fosgate P3's or T1's but a friend talked me into getting these instead and i would put my three championship 12's up against any of those and would give them hell

Own this sub close to a year... I am not looking to rattle the community but some times I have to turn it down. It is honestly the best sub I have owned so far. Again, not looking to make a boom (play hard), but my music is very nicely complimented with this sub, very nicely.

great sub

June 3, 2012

This has been a great durable sub. I have owned different subs in my life time, plus install professionally. For the price this is a sub you want to consider. yes there are better ones out there at a bigger price tag. I have 2 running @ 2ohm x 1 @ 1000w. they can handle alot more, but your ears might not. Mine started hurting so turned the bass down on EVERYTHING. My system is very modest compared to others so i havent given the subs all they can handle. I know one thing, I got behind a person and they gave me a finger saying I was number 1, the bass was so loud.

All I can say is - WOW!

May 12, 2012

This subwoofer is flat out amazing. I just installed it yesterday, and it's obviously not fully broken in, but it already sounds amazing. For a super good price, this subwoofer beats anyone I researched, even the higher value ones. The 94 dB per watt is incredible and makes this subwoofer so efficient. Have it in a Sound Ordanace Bass Bunker. Run this sub with a ported box and it'll sound amazing with a correctly hooked up amp.

Poor quality

March 27, 2012

These subwoofers are of the poorest of quality. After only 5 months two of them blew out and I do not doubt the third one is on its way. When you purchase the pioneer brand you would expect to have quality speakers. In the future I will be more cautious of the speakers pioneer sells and is making me doubt the quality of the other audio equipment it sells. I dont know if these subs were refurbished but they sure did have the characteristics of it.

Big bang for the buck!

March 26, 2012

Just got a pair of these bad boys today and they are louder than expected! Have them in a factory vented fosgate box that used to house a pair of P3s, powered by a crunch 1500.1 amp and they slam hard and hit the lows very well. They are barely flexing when i open the trunk yet in side my car the boom factor is intense sounds like i still have my much more expensive P3s! I have these wired in paralle @1ohm and unlike some of the other reviewers stating they wont handle it i am having no issues with the load. Must buy if youre on a budget these things slam!! But if you can afford it go with orion XTR pros way better excursion and durability.

these pound sooooo hard

February 25, 2012

I have two of these in a ford ranger ext. cab, and i gotta say i think its too much!! But i love it!! It is so loud the whole cab vibrates and the rear view mirror keeps falling down. Both in a 1.5 cubic foot box (sealed) paired to a kenwood KAC-9105D amp at 1ohm, the bass boost is at like 3. Don't think about it, just buy them!!!

These subs are great. I have two of them hooked up to a Kicker IX series 1000:1 amp and they knock sooo hard. Make sure you get new speakers to accompany them though or else your subs will completely kill your audio lol. Overall great subs that look amazing and are amazing build quality.
