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.
Vented / Ported
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.
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.
3.68 cubic feet
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 (banana clip ready)
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
31 Hz
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.

Number of Ports

Great build quality and sounds great

September 6, 2015

Box is build very well and sounds awesome. Goes perfect with the NVX VCW 12/2 or 12/4. The only criticism I have is the fact that there are 2 subs and only one terminal cup. I have 2 amps and I have to purchase a terminal cup and cut the box. Something that I really don't want to do considering the box is not cheap. I would have certainly give 5 stars across the board if it had 2 terminal cups

This box is obv perfect if you plan on going with the vcw122/124 series subs. Other 12" subs will probably work for this application but it was specifically built for the vcw12 series(as stated)

Pros: sounds amazing, real pleasing to the eyes and is made to spec for these subs.

Con: it's huge lol

I had to cut sheet metal on my trunk to get this to fit but I have an older car, so that wasn't an issue. Make sure this will fit into your application with ease; its like 3 feet long.

overall completely happy w the quality and price. couldn't have gotten anything better without spending like 300 on a custom enclosure.

box engineered for NVX subs to maximize performance
Christian B on Dec 19, 2015
I asked on your facebook page but know one will get back with me on it . The subs this box asked for is only 1.25 cf each total 2.50 CB . If the box says it's over 3CF so is there a type o or that's how it is ?

How does the single push terminal work, and would it work well with two subs whose maximum box specs is 4.0 cubic feet?
Quinton T on Aug 7, 2015
Best Answer: Hello Quinton,

We aren't sure what you are asking. The push terminals work just like all other traditional push terminals. We're positive we misunderstand what you're trying to ask, so please feel free to rephrase it, or call our sales team to elaborate.

As for the second part of your question, on paper it doesn't seem like a very good match. Obviously 4.0 > 3.68 cubic feet , but the main reason is because this enclosure is specifically engineered to optimize the NVX subwoofers. Not to say it won't work well with others, but fr that its best to contact the manufacture of the driver.

would 2 pioneer 12inch subs fit in this box? recommended cutout diameter is 11.1" and this is 11 1/4. would it still work?
Dubble-Jays on Apr 18, 2015
Best Answer: Hello JJ,

Being that the VCE212 is intended for a SPECIFIC driver, we cannot accurately answer your question. However, considering the diameter you specified is obviously SMALLER than the one provided by the enclosure, then it likely will NOT work, but its not a very big difference. We do not suggest taking that risk. .10 < .25 .

will this box be good for two Audiopipe TXX-BD2-12?

Best Answer: Hello,

The enclosure is Designed specifically for 2 12" VCW Series Subwoofers. Therefore, fitment cannot be confirmed or guaranteed. Besides fit, the specs make for a good volume for the drivers.
