Subwoofer Specifications

Subwoofer Series
Each subwoofer manufactured is part of a series. This is the name of the subwoofer's series.
Champion (Pioneer)
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.
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.
250 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.
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
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.
Urethane
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.

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
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.
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.
5-1/4"
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.

WOW!!

October 19, 2009

The drivers sound quality is very good. It blended very well with the main speakers. Bass is well defined and not one noted or boomy.. Even though It still needs some run in time to loosen up, I'm very impressed with it. Build quality is very good and looks to last a long time. The only con that I personally have is the fact that the woofers surround is made of foam. I would've preferred to see a rubber surround instead... Rubber lasts much longer and is much more durable. That's why it didn't get a 5 for features. But for a nice, low price, I really can't complain.. Used with the right amount of power and the right enclosure, this sub is a true sleeper..

Great Subs

January 7, 2011

I've had these subs for a while now, and after they break in they beat hard. They look sick, a little pastic-like, but they pound hard! Well defined bass, these subs are well built and support the high quality reputation Pioneer has built. I have 2 of these powered by a Rockford R500-1 amp, and the entire neighborhood and hear me coming from blocks away! They are a good buy.

Great sub, great price

November 11, 2010

I had a Dual brand 12" sub when I first started upgrading my car audio system, and no matter what I did, there was a persistent rattle, especially at high volumes. It sounded like it was coming from the rear deck underneath (where the 6x9s are mounted), but I never could pinpoint it. The other day I got some cash for a birthday present and decided to go ahead and "upgrade". I picked up this bad boy and the difference was immediately clear. Not only was the rattle gone (cheap Dual sub must have been the source, go figure), but this thing gets damn loud without any noise artifacts). Like one of the other reviewers, I'm pushing this thing with a relatively cheap 150RMS amp and it does the job just fine. The sub is installed in a 1.25cu foot box which is the recommended size, and I couldn't agree more. The last thing I need is a couple of bass blockers for my 6.5in speakers up front and my system is complete (until I decide to go ahead and upgrade the head unit too). This subwoofer has left me completely satisfied, and I'd recommend it to anyone.

In fact, my only complaint is that the sub didn't have optional male connectors for the speaker wire so I had to cut / strip the connectors off of the wire that came inside the sub box to attach to the push connectors on the sub. Hardly a serious complaint, but I'll give it 4/5 on features for that, I suppose.

March 23, 2011

OKAY so here it is, amazing, I agree with the foam surround though, bad idea by Pioneer, but other then that my Pioneer TS-W303R sub is in my single cab chev, powered by a whopping 1300 w Kenwood KAC-8152D amplifier! A high powered amp is a must for the best sound quality from this sub.

I had one of these for the first 12" sub I ever owned. It sounded great but unfortunately I had a little 220 RMS amp and it caught on fire when I was on my way to work. I recommend this sub to anyone on a budget that wants a little more bass in their ride but make sure you have a good enough amp.

I just got this subwoofer over the weekend and I would have to say it is a nice subwoofer. I have a 300 watt amp that puts out 150 watts rms and it is perfect for the subwoofer. I would definitely recommend this subwoofer to anyone.

Fried Voice Coils in 4 Months

April 29, 2011

I had these subs for about 4 months, no heavy use hooked up to a Rockford R500-1 Amp (2 subs wired in parallel, so a perfect match, no over powering) and I fried both subs after only 4 months of use. I'm attempting to get replacements under the warranty, since they were not over powered or ever plaed excessively loud. Before they blew, i loved them, but be careful, they might just only last about 4 months.......

I put two of these in a bandpass box with a memphis marine amp giving each 150 rms, and they sounded amazing, they hit hard for the price, the only problem is they get allot of crap for their plastic looking woofer, but they shut people up when they start to move air, great buy I would recommend them to anyone

Boom for the buck

September 25, 2011

I have one of these in a non ported box with an autotek 1000 watt amp pushing it and it bumps hard. It says 250 rms but I think its a little underrated. These things will really hit and if you have a solid amp and wire it properly, its just awesome. I've had it for about a year now and I haven't been disappointed. I would definitely recommend it especially for its awesome price.

I bought one of these, don't be fooled by the brand name or the plasticy look....lol...in the right box, with the right amp...this thing actually pushes a lot of air for what it is. Great value and durability, the makings of a Pioneer product. I did eventually take it back, but that's because I bought an RF sub so...but still awesome for a local store sub. If anything, this hit lower frequencies than my new sub, and it's half the price...lol..
