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.
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.
Square/Rectangle
Cutout Diameter or Length
The actual diameter of the hole in the subwoofer box. Length is the measured length per side of a square subwoofer or speaker opening.
11"
Maximum Speaker Depth
Your subwoofer or speaker must not exceed this dimension in order to properly mount in this enclosure.
10-1/4"
Total Box Volume
The internal volume measurement in cubic feet before subwoofer magnet displacement.
0.7 cubic feet
Box Volume (Each Chamber)
This is the total air space inside each chamber of the empty subwoofer enclosure. By matching this value with the recommended air space of the subwoofer, you will be able to know if the subwoofer will match this box.
Height
The height of the item, measured from top to bottom, in inches.
13"
Width
The width of the item from left to right (side-to-side) measured in inches.
14"
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"
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.
Gray
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.
Carpet
Tuning Frequency
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.

Well made enclosure

September 6, 2012

This enclosure is well made. Very sturdy and the carpeting is nice. The only problem with this product was the terminals. They worked themselves loose and were arching causing the plastic to melt.

heavy solid box...

October 12, 2007

at first i was skeptical about ordering this box because it was so cheap...u know the saying?"u get what u pay for"?well i bought this cheap but the box was built solid...but then again it was the sale price not the regular price-so u can look at it as pricey box for less...i got this box to house my single 12" dvc alpine type r woofer-and it hits clean bass but then it also helps to have a sub like the alpine type r...all in all im very satisfied i bought this box-it was way cheaper than buying it from my local in door swat-meat type audio store -they wanted 65 bux for a prefab sealed 12" box!!!they str8 scamming(in my opinion)...this was the cheapest store online i found for boxes among other things...
