Speaker Box / Enclosure Specifications

Subwoofer Size
Refers to the diameter of the subwoofer, measured in inches.
8"
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.
Bandpass
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
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.
10-1/2"
Width
The width of the item from left to right (side-to-side) measured in inches.
10-1/2"
Depth
The front-to-rear depth of the item, in inches. If the item is angled or slanted, this value is the bottom measurement.
15-3/4"
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.

Very solid, looks great.

March 26, 2011

I ordered this along with a MA Audio MA83XE for a friend. This enclosure is very solid and looks great, but didn't really sound all that great paired with the MA83. I'm not a big fan of bandpass for an 8" application, but the enclosure is really very nice and I would give it a second chance with another sub any day.

12" Single Bandpass Front Ported Sub Enclosure Box

October 26, 2009

If you're looking for a nice bass to your car this is the right box for you. I'd one of those about the title, and using it for almost five years and nothing wrong with it. The bass are amazing it hit hard, deep, even respond to the lowest frequency, Is it like the bass is surrounded you. Think about it you'll have sealed enclosure in the back of subwoofer, and the front is ported enclosure like horn. One you've one of these you'll never go back to other different boxes, and it's a great deal. I'm going to build other one of these for my other subwoofer. Hope you'll enjoy this product.

Beware!

April 7, 2010

EXTREMELY limited excursion space. If I was using any kind of decent sub this box would already be recycled. As I am just using an old Orion to fill in a garage system I am not too worried. Definitely an efficient box, but as with all bandpass boxes do not expect any range. You get 1 loud bass tone and thats it. Good build quality for the box, however the port and plastic side are of questionable material and quality.
