JBL GT5-2402BR
Factory Loaded, Dual 12" GT Series Subwoofer Enclosure

There is absolutely no doubt that the most time consuming and head-scratching part of a subwoofer-installation-project is planning the setup. This starts with finding the optimal enclosure for the subwoofers. Unless you are an expert in determining air space, box tune and port-dimensions, chances are you are going to want the easiest solutions that works best with your subwoofers. With the GT5-2402BR JBL has figured all the sciency stuff for you and has optimized the enclosure for the GT Series that are loaded into it. Right out of the box you can expect the drivers to work in conjunction with the enclosure to provide you with strong, thumping bass. The only think you need to worry about is finding an amplifier that works within your budget and making sure the 11-5/16"D1 x 14-3/8"D2 x 35-3/16"W x 15-7/16"H enclosure fits where you want it to.

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.
N/A
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.
2 ohms
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.
550 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.
1600 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".
95 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).
40 - 200 Hz
Xmax (millimeters)
Typically measured in millimeters, the Xmax value is the measure of a speaker cone's maximum excursion in one direction while maintaining a linear behavior.
14.2 mm

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.
Vented / Ported
Number of Subs/Speakers
This value represents the number of speakers or subwoofers that the enclosure accommodates.
2
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.
Hatchback Style, Angled Back
Height
The height of the item, measured from top to bottom, in inches.
15-7/16"
Width
The width of the item from left to right (side-to-side) measured in inches.
35-3/16"
Depth
The front-to-rear depth of the item, in inches. If the item is angled or slanted, this value is the bottom measurement.
11-5/16"
Second Depth
The second depth is used only when the box is slanted or angled. This value is the top measurement and it is measured in inches.
14-3/8"
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 (banana clip ready)
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.

Great Price Good speakers

April 4, 2014

I bought these jbl speakers just to have a lil bump in the trunk nothing too small and nothing too big. But when I installed these subs i was amazed at how they didnt require a lot of watts to power and that they can take more power as well. I like the overall look of these subs and the box and at the price i got them at i couldnt pass this up. Although I oly had them for exactly a month now this moring when I was listening to my favorite song, the subs just stop working and there was no sound so i hope they are not blown but i dnt even listen to them at very high volumes. But i would reccommend the subs jbl is a good company and the agents at sonix helped me out to purchase the right subs for me.

This box is extremely loud and clear and uses very little wattage to do it. It is very conservative on space and looks very attractive. You cant go wrong with this one especially considering what you are getting for the price in comparison to others.

Been a JBL devotee since my Dad heard them in a music hall in Houston 30 some years ago and bought his first set of L110's (still has em'), and I have all JBL's in my home theater set up. These just fit in the trunk of my Chevy Cobalt and rocks that little car...Got a great price and excellent service from Sonic

July 3, 2016

I managed to pick these up with some quality 12GA NVX wire for 180$ total with free shipping. These 2 12s blow my boston G1 10 inch out of the water. They move a lot of air and can get very loud. More than enough bass to go around in any normal system. These subs can easily render all my mirrors useless at half volume when the low notes hit.

Im running mine on a 500W kenwood class D monoblock with no bass boost.

We've decided to step in because the information you have received up to this point is incorrect, unfortunately.

The amplifier is a great match for the entire set of speakers. You do NOT have to "wire" in any special way, nor do you have any impedance concerns.
