Subwoofer Specifications

Subwoofer Size
Refers to the diameter of the subwoofer, measured in inches.
12"
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.
300 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.
300 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.
1000 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.
1000 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.
Polypropylene
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.
Rubber
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".
86 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).
30 - 1,000 Hz

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.
14-3/8"
Width
The width of the item from left to right (side-to-side) measured in inches.
17-5/8"
Depth
The front-to-rear depth of the item, in inches. If the item is angled or slanted, this value is the bottom measurement.
7-5/8"
Wood Thickness
The thickness of the wood the enclosure is made of, measured in inches.
3/4"
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.

Binding 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.

Nice subwoofer!

January 4, 2014

Was skeptic about buying Sony audio because Ive only purchased Alpine, Bose, & JBL in past. However, the price point and other buyers' reviews was enough to convince me into at least trying this sub even if it meant returning if I was totally unsatisfied. Speaker is now installed(with top of line wiring-pure copper) and I am pleasantly surprised. Enclosure is better made than some custom enclosures Ive seen and speaker hits as hard as other much more costly speakers I considered. For the money, as good as I could ever expect(DONT GO CHEAP ON AMP&WIRING)

The 12 inch sub is great buy if you're looking for a space saver, but as far as quality and endurance goes, it's what you pay for. I had a 10 inch kicker before this one and I would reccomend that.

Great

August 10, 2013

Sounds great in my 2005 single cab Silverado. Sub behind the passenger seat, amp under driver's seat. The only problems I had installing it were that I needed to make a bracket to hold the sub up because of the drop behind the passenger seat where the jack would go. (Drop on both sides but I put the sub on the passenger side) I have the sub on a 1000W 2-ch. amp and this sub hits hard. Held up to my abuse for about 2-3 months now with absolutely no problems. This sub is well worth the money.

Sony XS-GTX121LS subwoofer

January 4, 2013

I used this Sony in my Ford F150 standard cab pickup truck. It fitted great behind the passenger seat. No need to bother with selecting the proper box as it's all ready for installation. The sound experience inside the cab improved tenfold. Should be standard equipment on Ford pickup trucks. ;)

Worth the money

September 28, 2012

These things take a little while to break in, they still bottom out and I only have 500 watts on a pair of them. I think they would sound better with more power and a lower crossover point to get the pop out of them. You should buy kick grills for them if you want to protect them,mine are in the back of an suv facing the back bumper.Well made,solid hookup,comes with mounting brackets and screws,but,again,no grill to keep'em safe.

Works pretty good

July 25, 2012

I got this for my 2011 Ford F-150 XL regular cab truck and it fits perfectly behind the passenger seat. The stereo shop screwed the Kenwood amp right on the back of this Sony and the sound is great. With the four 60 watt Polk Audio speakers, this sub and Kenwood amp, the sound inside the truck has definitely improved. I kept the factory head unit and so far I don't think I'm going to change it.

great for the money, even great compared to much more $$$ models

May 2, 2012

I have this installed in my small trunk, really needed to save space but did not want to sacrafice low end punch for the old school rock I listen to. I am very satisfied with this setup. I am using a 500w kicker amp and a Kenwood head unit. One would be hard pressed even spending much more to get much better bass. I give this box a 5!

wrong buy

October 11, 2011

Dont buy this product if u want a shalow mount subwoofer. The only thing that is shallow is the box. It has a regular size sub install inside of it. when i perchase this sony product i was looking for a shallow mount subwoofer so i could save space in my trunk for my son's stroller. This is the wrong box to put this size sub and depth. It did not sound good and did not do the job for me. I end up taking it out and buying a new box for it. Now its install in a vented/ported enclosure made by BASSWORX. This SONY product fail to mention that its not a shallow mount sub otherwise i would've never bought it. Now it sounds a lot better.

Perfect Sub

September 9, 2011

I've had this sub for a month and I'm very pleased. This sub is just right for my GMC Envoy. It's true what the sound experts say about bass adds richness to all types of music. I've the setting a couple of notches above 0 & this sub really pounds. To conclude, I would recommend this sub to anyone just looking to add some nice "tight" bass to their system.

Kicks Hard For The Money. Don't expect it to keep up with very demanding bass though. If that's what you want, get a bigger box and spend twice as much for a sub.
