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.
10-1/4"
Total Box Volume
The internal volume measurement in cubic feet before subwoofer magnet displacement.
0.7 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.
Height
The height of the item, measured from top to bottom, in inches.
13"
Width
The width of the item from left to right (side-to-side) measured in inches.
14"
Depth
The front-to-rear depth of the item, in inches. If the item is angled or slanted, this value is the bottom measurement.
11.5"
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
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.

Sonic Box

September 21, 2013

This is a pretty good box. The frequency response is much more linear than a ported box. I used a TS-W3001D2 (high power but requires a smaller box due to Pioneer's "air suspension system." Even though the box isn't the loudest thing in the world (500 watt BASH amp), it's in a bedroom so it doesn't need to be. For that purpose, it sounds good and is plenty loud. The only thing I would be cautious of is the connector. It seems a little brittle and I'm not sure how it would fare if it was left to bounce around in a trunk.

Can't beat this for the price.

May 16, 2013

I would highly recommend this box. To fit my Stereo Integrity BM MKIII subwoofer I did need to carve out about 1 mm overall diameter for the mounting area but this was expected because of the solid basket design on that subwoofer. Most subwoofers with stamped or cast frames will not have this issue. Also, I would recommend using caulk around the speaker terminal as it has a pretty large gap between the plastic and the box itself. One of the terminals has rattled loose but will be easily fixed by tightening from the inside. Overall, I paid less for this box than it would have cost to build it myself, saving me time and effort. Great value!

I am impressed with the design of this box. The cut and build is solid inside out. I love the easy use of terminals as well. The lining are straight and durable. Carpet is just as you would expect for a good finish. Wood quality is good. It's not going to win show awards but for someone who needs a enclosure for a daily set-up, this can't be beat!

Nice box, sad terminals

November 2, 2011

I ordered four of these and they were exactly what i wanted. They look good and sound good. One big problem though- The terminals suck!! They're super cheap. I knew they wouldn't last the moment i saw them and sure enough they fell apart and actually melted so i had to switch them out. Other than that I liked the boxes.

Average quality at best.

October 2, 2011

The sub box was a perfect fit for my sub, with 3/4" mdf board. But was not of quality, the fabric. The fabric was not glues down properly or was it a strong material. It has started to peel in corners and from where the seams meet.

If you're looking for a good sealed box to push a single sub, this box does it well. I bought this box for a single Kicker Solo Classic 12" sub and the box is holding up great after six months of pushing that sub with a Kicker SX650.1 amp.

Works Great!

November 7, 2010

This box has held up perfectly! I'm using a bridged 1k watt Kenwood amp with a 3500 Watt Pioneer Premier Sub. (I blew out a previous Pioneer Sub with 1200Wat peak power, so I decided to increase the max rating with the replacement.) The bass response is very linear, as one would expect from a properly sized sealed enclosure. This is the only box which matched the sub's (uniquely small) space requirements.

I actually have used this box as an extension cabinet for my guitar amps. I had an extra 12" guitar speaker sitting around and wanted an inexpensive enclosure for it. This cab has worked quite well. I am very pleased with it. Very solid, no frills, works as advertised. I would buy again without reservation. That said, I am not sure how it would perform with a Sub, so there you go.
