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.
15"
Total Box Volume
The internal volume measurement in cubic feet before subwoofer magnet displacement.
1.5 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.
1.5 cubic feet
Height
The height of the item, measured from top to bottom, in inches.
13-1/2"
Width
The width of the item from left to right (side-to-side) measured in inches.
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.
17"
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.
Carpet
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.

September 1, 2014

This is just what the woofer doc ordered. The poly fill is already installed. The black carpet looks great. I'm installing a Rockford T-1 dual 4 ohm 12 in the box. I'm anxious to hear how this is gonna sound in my Mark VIII.

SEALED ENCLOSURE

May 8, 2014

Yes its a prefab box, it is constructed very well with .75" MDF. Solid no leaks.Carpet well done.Looks nice. Just match the air space you want for your sub and your done. I could not build this for the price i paid, so its a no brainer for me. If i was looking for ported or vented i would build one myself because of propper tunning. Just wanted something simple and this exceeded my expectations.

At the price they are asking,($40 shipped), this is a no-brainer. You'd be very hard pressed to buy the MDF used in this enclosure for the price they are selling the complete box for. Its true 3/4", ( I laid a caliper to it to check), and its advertised dimensions and airspace are spot on.

Seems very well made

January 22, 2014

I have a 2700w on a 3400w amp installed on this Subwoofer Enclosure and play it very loud all the time and still no air leaks. This box is Big in the inside, looks like a mini tunnel. The Poly Fill is pertty well laid out, you will have to move a little out of your way to access the Speaker terminals but trust me its no big deal at all. Since the box is so big for a single box, it does not move around trunk nearly as much as smaller single boxes. Had it about a month and two weeks since the time this review was written.

Just do it!

October 21, 2013

I totally expected this box to be a temporary solution to be replaced later by a "real" box. Well, I like it just the way it is. Won't be building that "real box" anytime soon! I have a Massive Hippo 122 and 3600 watt amp, so I expected the box to explode at some point, but it hasn't and it sounds great! Thick, heavy, tight, clean, handsome, cheap!!!

I use a JL Audio W3 in this box. It is firing to the rear in a Honda accord coupe. The sub has about 350 watts running to it. The box is very well built. The sound from it is perfect. I am very satisfied with my purchase.

decent box

September 17, 2013

I bought this box to house a 122x MOFO, which is kind of a tall order. The box is pretty thick and definetly acceptable for the price. Definetly plain jane. I wouldnt exspect it to stay perfectly sealed for more then a year with the sub I was useing but held up just fine for the 3 months I used it. Pretty good for the price and would definetly survive for a long time without any abuse.

Decent subwoofer enclosure

September 17, 2013

I wish it was a little smaller since it is a sealed enclosure. But it does put out a nice sound with the poly fil. I'm sure you can find better, smaller boxes

Great price

August 29, 2013

I'm running a rockford fosgate p2 in it. This box has held up great. i can hear a very small leak but only when I was checking for leaks. Otherwise it was inaudible from even a few feet away. Being 100% sealed is very crucial considering it is a sealed box. But overall id say that this is a great box. Cant beat the price. Nothing a little silicon cant fix.

The Cu Ft fit the sizing for my subwoofer
Aaron I on Aug 6, 2014
I have a Rockford Fosgate P1S4-12..this sealed box that says 1.5 cuft. it will do the job great for my 12 subwoofer?
Edrick F on Sep 10, 2014
Best Answer: Hello Edrick,

It absolutely will. The 1.5ft^3 falls right between the 0.70ft^3 - 1.80ft^3 volume recommendation, from the Manufacture; especially after displacement is figured in. Whether it will do the job for YOU, on the other hand, is going to be subjective and particular to Your taste. So, we suggest doing a bit of homework regarding the difference between Sealed and Ported enclosures.
