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.
10"
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
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.
200 watts
Total RMS Power Handling
This is the total RMS power handling of all the subwoofers included in the package or enclosure.

If the loaded enclosure or amplifier and subwoofer package includes more than a single subwoofer, then this is the total RMS power handling for all of the subs combined.

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 giving your subwoofer(s) 75% - 90% of the recommended RMS rating.
200 watts
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.
800 watts
Total Peak Power Handling
This is the Total Peak Power handling of all the subwoofers included in the package or enclosure.

If the loaded enclosure or amplifier and subwoofer package includes more than a single subwoofer, then this is the total peak power handling for all of the subs combined.

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.
800 watts
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) w/ Carbon/Glass Fiber
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.
Woven cloth radial urethane
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".
89 dB
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 - 144 Hz
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.

Enclosure Specifications

Box Type
Represents the style of the enclosure. Be sure to purchase the appropriate enclosure type and internal volume that will be compatible with your subwoofer's recommendation.

Sealed - Sealed boxes are those that have no holes or vents in it. The only hole in a sealed box is where the subwoofer is installed. Smaller sealed boxes require more power than a larger sealed box. They provide a tight, accurate bass, while the larger sealed enclosures provide a "boomier" and louder bass.

Ported / Vented - Ported/Vented Enclosures provide an even boomier, louder bass, but less accurate then a small, sealed box. Ported enclosures typically require more airspace per sub and also less power output from an amplifier to perform correctly.

Bandpass - Bandpass enclosures make subwoofers perform efficiently, but loose. The bass is not as "boomy" as a ported enclosure nor as punchy as a sealed enclosure. Bandpass enclosures work well with lower to mid-level subwoofers.
Sealed
Number of Subs/Speakers
This value represents the number of speakers or subwoofers that the enclosure accommodates.
1
Box Style/Shape
The box style or shape refers to the actual shape of the box. Square and rectangular boxes are straight-edged boxes on all sides, whereas hatchback and truck style enclosures feature an angled front or back design that allows for installation in places short on depth such as single cab pickup trucks. You can also use such enclosures in hatchback cars or other vehicles where space is a premium. Tube and cylinder shaped boxes were made popular by Bazooka and are a great option for those looking for a nice amount of bass without sacrificing lots of space. They may even fit in locations that slim truck boxes cannot fit in. If the enclosure is vehicle specific, we encourage you to read the product description to find out which vehicles the enclosure is made for.
Truck Style, Slim with Angled Front
Height
The height of the item, measured from top to bottom, in inches.
11-15/16"
Width
The width of the item from left to right (side-to-side) measured in inches.
18-7/8"
Depth
The front-to-rear depth of the item, in inches. If the item is angled or slanted, this value is the bottom measurement.
5-7/8"
Wood Thickness
The thickness of the wood the enclosure is made of, measured in inches.
5/8"
Number of Terminals
The number of terminals the enclosure has. Each terminal represents 1 positive and 1 negative.
1
Terminal Type
Spring clip terminals work best with bare wire connections with small-gauge speaker wire, or pin-type connectors.

Binding post terminals are a sturdier, more versatile type of speaker terminal. Because binding post terminals are are threaded, you can tighten them down against the wire or connector for a tight, clean connection. The most popular style of binding post terminals is known as a "5-way binding post". This type can accept bare wire, or any of the common speaker wire connectors. Binding posts with the option to be used with banana clips are even more versatile

Spring posts are a hybrid of the two. Instead of using a thread and "screwing" them tight, they use a spring to allow the wire to fit and tighten against the terminal.

Spring posts
Box Exterior Color
The color of the enclosure's exterior/outer finish.
Black
Box Finish
The material used on the outside of the box. Most boxes are carpeted to prevent exterior scratches; however vinyl is popular as it can often be color-matched to a near exact look of your leather factory interior.

Very happy guy

August 16, 2013

I was once a young wipper snapper and had to have the loudest stereo and have had several setups over the years. I am the happiest with my current setup and this 10" pioneer is part of it. I no longer want loud. I want quality sound and perfect balance between lows mids and highs.

I have this sub in my 06 Nissan Frontier crew cab under the rear passenger seat. It fits but I did have to trim one of the legs on the sub box for a perfect fit. I am not running an amp to my mids or highs and it sounds great. I am powering the sub with a small inexpensive Sony monoblock amp and it's very accurate with tight bass. You won't win any bass competitions but if your space is limited and you want great sound quality and that extra thump look no further fella, you found it!

Great Subwoofer!

May 16, 2011

Put one of these in a 06 Chevy 2500HD crew cab. Fit nicely under the rear seat, eliminating need for custom enclosure.enclosure is very nicely made, and subwoofer itself seems very good quality. Paired it with a Pioneer GM-3400T, these seem perfect for each other. Filled the lack of bass from the stock system and then some! Hits really hard for a shallow mount subwoofer. Better than any other shallow mount I have heard. Sonic has the lowest price I could fine and as always great service!!!!

worth every cent

March 12, 2014

This gives big sound at a small price.

I bought it to fill out the sound in my VW Beetle and actually had to turn the amp down to a quarter to keep the balance right.

The enclosure is not too big and seems very sturdy, it even comes with brackets and self tapping screws to fix it in place.

I bought it with the Kenwood KAC-1502S and a wire fitting kit all work very well together.

Adaquate

January 23, 2014

This 10" subwoofer will give you adequate bass. If you really want to have more than enough bass this won't give it. I installed an Infinity 1060w in my other car and it showed me how lacking this Pioneer TS-SWX251 was. I used a sealed single 10" subwoofer angled truck or hatchback box enclosure of about .75 cu. ft. filled loosely with poly fill for the Infinity 1060w install. At the same amp and head unit settings as used with the TS-SWX251 the Infinity was about twice as loud and just as clean. They both take up about the same amount of space.

awesome product

October 13, 2013

This subwoofer, enclosure, amp and kit worked flawlessly for an install unto my 05 Tacoma access cab. The enclosure fits flush on the floor behind the seat and takes up nearly no space. The amp hides nicely under the seat and the wiring was top notch. The overall sound quality was excellent as a addition to my stock system and gave it a nice deep thump that is not overpowering. The only drawback to the amp is it doesn't have and external bass control unit for easy adjustment. But a great product for a great price and sonic shipped really fast

Love It!!

March 5, 2013

I just had this installed in my Trailblazer yesterday and I must say that I love it!! It is paired with Polk DB6501's in the front and DB651 in the rear with a Kenwood KAC7005PS and a Pioneer 8400BH. This sub rounds out the sound system nicely and will bump when pushed. I highly recommend this if you are looking for a tight musical bass speaker. I ma very impressed with the sound from this little package. I have no complaints with it at all.

pioneer subwoofer and box

August 13, 2012

This is a great subwoofer and matched box. It works great in my tundra. Good clean base. It takes awhile for the music to loosen up the surrounds. The more you play it the better it sounds.

Not bad for the space

June 21, 2012

This sub works nicely in confined spaces, compared to my wife's solobaric it's weak, but that's not what the intent of this product is. The sound is nice and a rich deep bass was added to my car with this and it does not take up very much space at all.

I would recommend this for anyone short on space looking to just add more bass to a system.

just what you migjt expect...maybe better

November 27, 2011

This is a decent sub. It plays best facing the rear. I have a sedan and tried it facing front, down and up... but like I said rear facing is best. Better sounding over time. I use an MTX amp to push it. It definitely makes a huge difference from factory. But not going to rock your neighborhood. Good overall. But only if you're tight for space. Otherwise get a regular sub and sealed or ported box.

Big sound from a small space!

December 23, 2013

I bought this sub because of its small size. It sits in the back of a small hatchback. I was originally worried that 200w rms would not be enough but it is more than enough for my taste. Dont expect earth shattering volume, but if you want to round out your system with little space this is a great choice.

Pioneer TS-SWX251 Sub

June 7, 2013

I own a 2004 GMC extended cab pickup with Bose speakers. It's a great system but missing a deep bottom end. My son & I installed the Pioneer unit. It fit perfect under the back seat. The sub really helped improve overall sound quality of my system. We were so impressed that my son bought one for his Focus ST!

I have a 2003 Mustang GT and this small unit fits great in the trunk. Just enough bass to round out my system. Not overpowering which is exactly what I wanted. Didn't want a large box taking up the entire trunk. Built a small shelf around the unit to mount my Amp. Great price at Sonic!

blew me away!

December 14, 2012

First of all, I got free shipping with this and it got here in 2 days, in mid December! I was very pleased with that. I was a little nervous how this was going to sound in my SUV at first. It was replacing a 12" forward facing sub. When i got everything hooked up I was amazed how good it sounded. Way better than my 12. It sounds very clean and crisp. I couldn't be happier.
The only down i see with this is how short it is. the sub was coming awfully close to the floor when i had it cranked up. but it was an easy fix!
