Speaker Box / Enclosure Specifications

Subwoofer Size
Refers to the diameter of the subwoofer, measured in inches.
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.
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.
Hatchback Style, Angled Back
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.
Maximum Speaker Depth
Your subwoofer or speaker must not exceed this dimension in order to properly mount in this enclosure.
Total Box Volume
The internal volume measurement in cubic feet before subwoofer magnet displacement.
0.749 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.
The height of the item, measured from top to bottom, in inches.
The width of the item from left to right (side-to-side) measured in inches.
The front-to-rear depth of the item, in inches. If the item is angled or slanted, this value is the bottom measurement.
Second Depth
The second depth is used only when the box is slanted or angled. This value is the top measurement and it is measured in inches.
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.

Binding posts
Box Exterior Color
The color of the enclosure's exterior/outer finish.
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.
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.

Great sounding, durable box.

December 3, 2013

So far I've had this box for well over a year with my Kicker CVR12 and this thing doesn't loose a beat. Lets the sub hit hard for the limited space. There isn't anyone who doesn't compliment my music after seeing such a small enclosure in my trunk. Highly recommended box if looking to save space.

I mounted this sub in a custom fiberglass enclosure. It is a sealed enclosure with 1.5 cubic feet of volume. I can not believe how hard this speaker hits. It hits almost as hard as my 2 alpine type R 12's. This speaker looks good, sounds good, and was at a great price.

It is good enough and I got what I paid for.

September 27, 2013

I love this sub box but it's not the best out there. The carpeting job was just a little shabby and the packaging left little white Styrofoam bits all over which were annoying to get off.
But I'm never going to look at it. I don't have a show car. It's functional, well-built, durable, and very, very fairly priced. I can deal with imperfect carpeting.

Do your research before you buy! Research, research, research! I bought this sealed box because I wanted tighter bass for pop and classical music, and I wanted this shape because it backs up nicely against the rear-sides of my back seats in the trunk.

Awesome Box!

May 3, 2012

Pros: Great box that makes my sub hit pretty well and bass is very crisp, and for the price, it's a great buy. Small and compact, and fits perfectly against my back seats (which are angled back).

Cons: Was a bit smaller than I had expected, so it may not make your subs hits as hard as a larger/ported box.

*I filled my sub with some PolyFill (which is just polyester stuffing, $20 here $4 at Walmart), or you can use some Dynamat which will give best results, but it is a bit pricey. PolyFill made sound a bit deeper and sounds a lot better than just an empty box.

Fort Worth, TX

Good enclosure, a little sloppy looking

February 19, 2013

This box is constructed good, although I would follow the advice of others who suggested using loctite on the terminal nuts inside the box. Outside, the box looks ok in general, but it isn't clean. The corners were showing on 2 corners and there were little spots of glue in a couple of areas. If you aren't planning to show off your box and don't mind it looking less than great, this box performs just fine.

This box can handle the strongest 12in subwoofer pioneer can throw at it (1000w nom)

October 6, 2013

I'm only 17 but I do know my way around car audio I bought a pioneer tsw3002d4 to go in this box because my sub's specs required a .8 cubic foot box and this box was cheaper than the ported box so I decided to go for this one and Im so glad I bought it because it works great with my sub. The internal volume for this box I believe is .749ft^3 and it sounds crystal clear.
The only thing about this box that I didn't like is that the terminals are not caulked on the inside, and the outside connections loosen up really easily if your playing it loud for too long without tightening them down every once and a while. So I suggest putting the wire into it with banana clips or putting the wires in the holes then tightening them down with a wrench with cloth over the nuts so you don't rub off the brass plating. I also forgot to mention that I went in and sealed my terminals with some silicone that my dad had laying around so now my box is 100% airtight.
