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.
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 - 180 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
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)
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.
.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.
2.05 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"
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.

May 6, 2011

I have 2 of these subs in a ported box wired to 1 ohm getting 600 watts each. all i can say is holy s***. Goin strong with no issues for 4 monthes now. Its tremendously loud for the price. My system beats out my friends that have more expensive subs than me. On a budget or not, i highly recommend this sub.

Good subs for price

May 5, 2011

I purchased these subs and built two enclosures for a home sound system. It didn't work as well as I planned, but that was the fault of my poor enclosure job. The subs respond well to input and seem fairly well built. I will test them will full power at some point, and I'm sure with the proper enclosure, they'll get the job done.

amazzin sub

April 22, 2011

I only have on of these subs in my 2001 Xterra and it sounds amazing. I have it hooked up to a 1000 watt Hitron amp that puts out 600 RMS at 2ohms which is what I have my sub wired to. So I'm easly over powering this sub by 200 watts RMS and it couldn't sound better. I've had it for about a good five months now and there is no sign of wear on it or the amp. So over all Pioneer is by far the best brand if you don't want to spend much and they can take a beating. And with just one sub it shakes everything in my car and thats when this bass knob it only half way up and the radio is on 8.

Works well in ported or sealed boxes

February 20, 2011

I have my own stereo buisness and use these speakers for many installs. They perform well in ported or sealed boxes. I push them with the Power Acoustik 2000 watt class d amps and have never had one fail. Great bang for the buck. You can remove the magnet gaurd and lesson the mounting depth by 3/4 of an inch.

Only subs I wanna talk about.

January 22, 2011

This Subwoofer is great for its price; ordered it for my little brother as a single 12", its his first sub and he loves it. I've personally owned "STRICTLY" pioneer subs since I started my hobby. I've heard everything: Rockford, Kicker, MTX, Memphis, FI BTL's, JL Audio, Orion, Infinity and literally: nothing compares. This equipment is very sophisticated and deserves an amplifier that will serve it justice. So long as you know your basics: Box Volume, Power needs, and crossover values you'll be pleased. The only subwoofer meant to last and sound deadly accurate is Pioneer. Dont be fooled by the price, Sonic Electronix is as good a bargain as you can find.

Bringing the bass

January 11, 2011

These are fantastic subwoofers for the price. I have them connected up in their maximum power configuration and at times I believe my Suburban is going to explode before they blow. Very tight bass for anyone looking for an SQ configuration and I'm sure SPL'ers will drool at the pressure they produce.

awesome subs for the price

December 23, 2010

I recently picked a pair of these Pioneers up for the wifes Xmas gift.. Car is a 2001 sunfire (coupe).. Subs are in a custom built ported box i made..3.5 cubes net tuned at 34 hertz with 14" of port per cubic foot.. Amp is a audiopipe mini 1000d running at 1ohm.. amp pushes a solid 790 watts rms..(according to my clamp meter)..impedance rise to 1.3 ohms.. She has a shuriken bt35 under the hood and a 1 farad cap..voltage never goes below 13.3 volts.. in short these subs in the proper box can be down right nasty...absolutely love the way they sound,, if you buy these do a proper box and power and u will be amazed at the quality sound..

I listen to alot of dubstep and rap on my single tsw308d4 and it has never failed, it responds intensley good on double bass for metal too and adds alot of clean bass for any other genre i listen to like folk or classic rock or anything. i would get another 308d4 in a heartbeat, but if i get another sub, it's gonna be 2 15's, but i need the bass to tingle my ears and eyebrows, not just shake my car and my insides.

great speakers

October 3, 2010

I have two of these in my Jeep Cherokee. they have a lot of bass and can be tuned to be more like normal, but i prefer the bass. If I had the other speakers to go with them it would sound great. I've got stocks but need tweets and mids. I have older pioneer deck and older Jensen 460 amp, I built a custom box as per the spec sheet. I could probably get more out of them but over the years I have learned not to turn my gain up and save from fixing my amps.
