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.
4.60 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.
2.30 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.
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.

Spring posts (banana clip ready)
Box Exterior Color
The color of the enclosure's exterior/outer finish.
Black Carbon Fiber Face with Black Carpet
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.
Carbon Fiber Painted Finish
Tuning Frequency
41 Hz

Port Details

Number of Ports

Kicked Some Butt

September 16, 2016

I was running my two Digital Design 12 s in a sealed box with 800 Rockford watts .I put them in Atrend box and my nose hairs tinged. I Went with an Alvine V 9 so only had 500 watts but made the bass twice as hard even with less power! Looks amazing too!

Will this box work with or is it good for two orion hcca 124 12" sub if not do you have a box that will work with these subs thanks?
A shopper on Oct 5, 2014
Best Answer: Hello,

Unfortunately, it is a 'No' to both questions. Although it can be Made to work, it defeats the purpose of the design of this enclosure; The outside 'cover' will obstruct the HCCA124 from mounting properly. In addition, the Air Volume is under the specs outlined by the manufacture, and will drop further once the woofer has displaced Its volume. We stand by the manufacture's suggestion of having a Custom Enclosure built for you vehicle and subs.

1) Will this box fit in the trunk of a 2008 Mitsubishi Lancer?
2)Will this box work with 2 SoundQubed HDS312's?

Looking to put to RF P3's dual 2ohm in this box. First off, do you think this box will work well with those woofers? Second question: I used my box calculator and it said, according to the outside dimensions given, the volume was 4.545cf. That's close to 4.6 as advertised but I don't see that allowing for the port dimensions. Did I miss something?

Is this box good for 2 w6v2d4 subs?
Yukon on Aug 31, 2015
Best Answer: I looked up the recommended ported box volume for those subwoofers and it suggested 3 cubic feet of air space and this box has 2.30 per chamber so this will be more than enough for your subs. I might even suggest a smaller box volume for those subs.

Will this box work for two massive audio summo's ?
Brian G on Dec 1, 2014
Best Answer: Those massive audios call for 2.33 cubic ft per woofer. This box gives you 2.3 cubic foot per woofer. It would work perfectly. I have this box. It's really big and heavy and very well made. Tough to carry by yourself. I had to use a hand truck to get it out to my car. The carbon fiber piece (it's made out of wood) that's on the front, One of the corners of it was smashed to hell during shipping and they hand make it after you order it , So it's like a month wait and I didn't wanna wait another month if I returned it. My only complaint is it's tuned a lil bit high at 41 hz. That's the only thing I don't like about it. I'm picky though. You won't be disappointed. It Fn gets down man!! I just wish it hit the lower 30s but, Man from 35 hz up, It HAMMERS !!! str8 up If you have the room for it it's worth it. Definitely measure if your putting it in a trunk. I got it in an outback wagon and it takes up almost all the cargo space.
