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.
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.
2.50 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.
1.25 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.
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.
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.

Sounds awesome, great quality

April 29, 2016

I have 2 Pioneer TS W3003D4 12" subs in this box. I was doubting the airspace but let me tell you, if you want these subs to last, and you want to run them at a true 1200 watts RMS, do yourself a favor and get this enclosure. Any bigger and you might wreck the subwoofer suspension or motors after a bit. The subs are VERY loud in it. I didn't want to deal with the whole prefabricated ported box crap (yet) and I did not want to pay $200 for a nice custom made ported enclosure. Plus, I really hate how ported boxes only allow you to play music a few hertz around tuning frequency. I wanted clean precise bass at all frequencies. Trust me sealed boxes CAN pound, and cleanly. Only thing I would STRONGLY recommend is you dont even use the speaker terminals on the box. I have my 12 gauge subwoofer wires ran through the box via a drilled hole, and into a 2 in 1 power/ground distribution block (1 distribution block for each sub, 4 wires in from sub, 2 wires out to amp), each distribution block has two 8 gauge wires going from it to my subwoofer amp speaker inputs. If you dont want to spend more money, you can just connect some 12 gauge wires straight to your amp through a drilled hole in the box as previously mentioned.

Drill a hole in each chamber, wire the subs with 12 gauge wire to the amp and seal the hole with a hot glue gun, or expanding foam spray and silicone. Let it dry overnight.

That being said, the bass on 2 12s in this box, and my SoundQubed 1200 mono amp is very loud and hits hard. Roof flexes and windshield flexes when I want it to. But of course, if I want very musical bass, this box does it flawlessly aswell. It does it all. Deep bass, low bass that shakes everything hard, and great punchy and "kicky" bass if you like Rock or Electronic music.

Great box

July 8, 2016

This is a very good constructed box, and the "carpet" finish is flawless. The spring loaded terminals are a breeze to use, and hooked up easily using 12 gauge wire. However, the reason for only three stars on ease of use was because the cutout diameter was slightly too big for the Alpine subs I installed. But because of the power supplied to them, I left the original baffle on the box and glued and screwed a new baffle with the correct size cutouts on the box and covered it with exact fabric. Can't go wrong with a double baffle lol...great box overall.

Tight sound

Box is well built. Handles hard knock with no box vibration. Make sure you stuff the box with poly. Makes it sound twice as big

Will this be a good fit for my two Pioneer TS-W3003D4 subwoofers? Looking for the best sealed enclosure I can find. If better suggestions let me know. Thank you!
Brian on Mar 19, 2017
Best Answer: Looks like those subs require 1.25 cu ft each and the enclosure is 1.25 per side so yes, these are exact spec. It's a nice enclosure for the price using the 3/4 MDF.
