Speaker Box / Enclosure Specifications

Subwoofer Size
Refers to the diameter of the subwoofer, measured in inches.
10"
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.
9-1/8"
Maximum Speaker Depth
Your subwoofer or speaker must not exceed this dimension in order to properly mount in this enclosure.
11-1/4"
Total Box Volume
The internal volume measurement in cubic feet before subwoofer magnet displacement.
0.77 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.
0.77 cubic feet
Height
The height of the item, measured from top to bottom, in inches.
12-1/2"
Width
The width of the item from left to right (side-to-side) measured in inches.
12-1/2"
Depth
The front-to-rear depth of the item, in inches. If the item is angled or slanted, this value is the bottom measurement.
12-1/2"
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.

It is square and holds my Infinity sub. Is great and I have no complaints. I bought this awhile ago for $19.99, which is about as much as a wood box should be worth.

I got this box for an Earthquake dbxi10 and thankfully the sub fit right in despite me thinking the measurements for the cutout were a bit off. The little bit of polyfill lining is a nice touch. The box felt secure and solid with a good bit of weight for the quality of wood. It definitely didn't feel like a cheap particle board box. The carpeting was on snug and looked good as well. Great pre-fab box for your sub. I expect it to last but can't say for sure as I just got it in recently.

Box is built damn well for the price. Only complaint was some sealant was missing in some spots, especially in the corners. Not a big deal though, I just bought some silicone sealant and filled in the missing gaps.

Box is well built, its hard to mess up building a small sealed box.. The only problem was sub opening wasn't large enough for my sub, 5 minutes with a jigsaw and vacumn took care of that though..

This product is cheap, but is worth much more than the purchase price! It's built just as if I purchased a sub box worth 3 times as much! It was really easy to screw in the screws for my Alpine sub.

Strong, clean, durable box! I had my JBL GTO1014D in this box, then my NVX VSW104 in it! Both subs sounded great! Very tight & accurate, but deep & loud as well! Would definitely recommend to anyone who likes sealed boxes! Thanks Sonic for great pricing and prompt delivery!!!

Decent box

January 10, 2012

This is a decent cheap box, says sealed and it was, all except the speaker side of the box, I sealed that my self and then mounted my FLI Audio FL450S-F2 amp to the top of the box. After amp was mounted in went my JL Audio 10W0v3-4 this is a great combo, I set this in my jeep rear facing in the corner and the bass really hits hard. I would reccomend this box.

How many hertz is recommended for a ported box cerwin Vega 104d 250rms? and the displacement for it also?
Shawn Graves g on Dec 30, 2014
Best Answer: If your talking about a pre tuned box at like 32 hertz of 28 hertz stuff like that, don't do it that's overkill for that small sub. it doesn't take alot of power and will be better off in a smaller ported or sealed box, but not a truck enclosure lol
