Speaker Box / Enclosure Specifications

Subwoofer Size
Refers to the diameter of the subwoofer, measured in inches.
15"
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.
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
Maximum Speaker Depth
Your subwoofer or speaker must not exceed this dimension in order to properly mount in this enclosure.
17"
Total Box Volume
The internal volume measurement in cubic feet before subwoofer magnet displacement.
2.54 cubic feet
Height
The height of the item, measured from top to bottom, in inches.
16-1/2"
Width
The width of the item from left to right (side-to-side) measured in inches.
21-1/2"
Depth
The front-to-rear depth of the item, in inches. If the item is angled or slanted, this value is the bottom measurement.
20-1/2"
Wood Thickness
The thickness of the wood the enclosure is made of, measured in inches.
3/4"

Decent Buy!

November 10, 2013

Although the hole for the sub was bit small, it seems that this sub box is sturdy and tuned nicely. I had to sand it down to fit the sub in there but other than that it is doing its job and at a great price! (Not to mention it looks good too)

Nice Box

October 22, 2013

Well i love this box, it looks great, its what my sub needed. I own a 15inch Polk Audio MM1540 nice sub by the way. A lot of boomy bass, it sounds very nice i would recommend this to any one with this type of sub. One draw back is that this enormous box cant fit the trunk in my 2001 BMW 325i, sadly i had to resort to my SUV:( Its a good value and I love it!

Good looking and high quality ported 15in. box

June 5, 2013

I purchased this box to house a 15in. alpine type-s subwoofer. It's internal dimensions are very close to the 2.6cu ft. that alpine recommends as ideal for this sub. Also, it's nice and loud without sounding sloppy. I really wanted a boomy sounding ported box to deliver the deepest bass response and this is perfect so far. Looks great in my trunk and the black/grey matches my black car with charcoal interior very well. Only negative is that the box wasn't wired for the sub already, but that was cheap and easy to do myself. Overall very pleased with this ground shaker! =)

boom for your buck!

January 3, 2013

I am so happy with this box. I didn't know how much of a difference it would make.. the box I had before got damp due to a window leak and pretty much vibrated itself into a rattling P.O.S. this new box was a very inexpensive and much needed replacement, all pro's no con's! Thanks Sonic!
