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.
Vented / Ported
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
Maximum Speaker Depth
Your subwoofer or speaker must not exceed this dimension in order to properly mount in this enclosure.
10-1/2"
Total Box Volume
The internal volume measurement in cubic feet before subwoofer magnet displacement.
2.25 cubic feet
Height

good box for the money

June 12, 2014

There was a couple of issues with the box but it could be from the shipping of it. But it rattled like it wasn't glued or sealed properly. The corners were damaged but the fit for the sub was good. I had to reseal the box and screw it together to keep it from rattling.

Made 1 of my RE Audio SEX12 subs sound like 2

January 29, 2014

Made 1 of my RE Audio SEX12 subs sound like 2. This is a very nice box built to my sub specs, shakes the whole car. If you are thinking of getting this box, get it. I took the box to 1 of my favorite Car Audio shops around me and the box guy told me that he would have charged me $125-$150 to build me a box like this.

Great Prefab as Usual

October 7, 2013

I've had a variety of Ground Shaker's boxes (8", dual 8", 10", now SPL 12") and they make great boxes for being prefabricated. The 12" SPL box sits perfectly in the trunk of my IS350, which is exactly 30.75" from the left to right inner wheel walls.

Superb Sound

October 6, 2013

This box is perfect for the kicker cvr or cvx and has amazing sound quality. However, you must be careful playing bass notes below 20 hertz because a sub like the cvr tends to have a loss in motor control and makes an awful popping noise due to the cone having no support in the ported box.

sweet box

March 3, 2013

For a prefab box you really can't go wrong with this, terminals on the inside are a little chincy, but seems to be constructed well and has a good sound to it.
