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.
13"
Total Box Volume
The internal volume measurement in cubic feet before subwoofer magnet displacement.
3.77 cubic feet
Height
The height of the item, measured from top to bottom, in inches.
16-1/2"
Width

not my first choice

August 14, 2013

It's a decent box but lacks in quite a few areas.. it's not tuned properly, the port wall is made from 1/2" MDF which affects the quality of sound. definitely not worth the money.. spend a little more and get a good box.

Great Sound!

July 25, 2013

Overall, This is a great box to have in a system that you want others to hear from really far away. This box really makes my Type-R 15 sound incredibly loud. I recommend tuning your subs down to a lower frequency in order to get them to sound perfect in this box. I would definitely recommend this product!

I replaced a cheap ported box with this box and I'm impressed. It hits lows that old box did not. It looks great and sounds good too and it's not tuned too high like a lot of prefab boxes.

Just buy this box

February 10, 2014

I have an audiopulse axis 2300w rms sub screwed into this box and it truly sounds amazing. The sound is superbly smooth even though it obviously wasn't built to specs with my older sub. It also delivers on sheer power output, enough to virtually rattle apart my cavalier (it's a GM... not surprised). I had to do some grinding to get this beast to fit but it was worth it. Only problem is now the trunk won't stay open... partly due to dynamat and a couple cut brackets. I couldn't be happier with it though.

Amazing sound

December 20, 2013

This box is big for a 1996 accord but the sound quality is amazing. im pushin 5500 watts to an audiopipe 15 sub and this box sound deep. better then any other box i used, and ive been through alot. if your looking for a nice box built well and sounds great this is the box for you. be careful though my box came with a broken sub wire terminal. i have plenty so that was no big deal for me> but still an amazing box
