Speaker Box / Enclosure Specifications

Subwoofer Size
Refers to the diameter of the subwoofer, measured in inches.
12"
Subwoofer Cutout Shape
This is the shape of the enclosures cutout hole and defines the style of subwoofer that can be installed.
Round / Circle
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.
Ported Bandpass
Number of Subs/Speakers
This value represents the number of speakers or subwoofers that the enclosure accommodates.

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.
Square/Rectangle
Maximum Speaker Depth
Your subwoofer or speaker must not exceed this dimension in order to properly mount in this enclosure.
16"
Total Box Volume
The internal volume measurement in cubic feet before subwoofer magnet displacement.
3.35 cubic feet
Height
The height of the item, measured from top to bottom, in inches.
13.5"
Width
The width of the item from left to right (side-to-side) measured in inches.
33.50"
Depth
The front-to-rear depth of the item, in inches. If the item is angled or slanted, this value is the bottom measurement.
18"
Wood Thickness
The thickness of the wood the enclosure is made of, measured in inches.
Number of Terminals
The number of terminals the enclosure has. Each terminal represents 1 positive and 1 negative.
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.

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.
Compatible Vehicle Make and Model
The model of vehicle that this vehicle specific product is designed for. Please keep in mind that engine variations can affect the compatibility of the products.

Great price to value ratio

May 25, 2014

This box is large and heavy. Wall thickness is good and resonance is low when applying the "knuckle knock" to it. Quality is important and this box has it. Good carpet, sealed in all corners, and the holes fit Infinity subs perfectly. I expect a lifetime of use from this box since it will actually be used in my home.

Nicely made dual sub enclosure

February 11, 2014

Purchased this dual 12" sealed enclosure to use with two Infinity reference 1260W subs. This is a large (for a car) enclosure but that's what I was looking for. I added two 1-1/2" dia x 9" ports to each chamber giving approximately 25 Hz tuning for each chamber. The Infinity 1260W's work real well with this setup. The enclosure is nicely finished and the Infinitys dropped right in. Added a couple of grilles to protect the drivers, mounted the amp to the backside, and presto - great bass ! I have no rattles from the enclosures, and though it is quite wide, it does fit into my 300's trunk nicely, and I still have room left for hauling things. For the price with the free shipping, you can't beat this enclosure. Highly recommended!

I purchased this box for 2 new Lanzar subs, feed by kicker ix1000.1. Holy crap, its loud. Windows in car literally shake & extend to seal limits. I'm very impressed with this box thus far that I'm considering buying another one very soon, for my other vehicles. Worth every penny. A++++ product, highly recommend to anyone whom has the space/room for this box.
