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.
Bandpass
Number of Subs/Speakers
This value represents the number of speakers or subwoofers that the enclosure accommodates.
2
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.
11-1/8"
Maximum Speaker Depth
Your subwoofer or speaker must not exceed this dimension in order to properly mount in this enclosure.
6"
Total Box Volume
The internal volume measurement in cubic feet before subwoofer magnet displacement.
3.0 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.
1.5 cubic feet
Height
The height of the item, measured from top to bottom, in inches.
14"
Width
The width of the item from left to right (side-to-side) measured in inches.
29"
Depth
The front-to-rear depth of the item, in inches. If the item is angled or slanted, this value is the bottom measurement.
19"
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.
2
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

Port Details

Number of Ports
The number of ports the enclosure has.
4
Tuning Frequency
Port Diameter
The outside diameter of the port. Check the product's owner's manual for the recommended port diameter for your sub.

This box is amazing!!!

May 7, 2013

I just got this box a couple days ago and i couldn't be happier! i have 2 12" audiobahns each 1000 watts, and the sound quality was stunning. crisp and clear bass fills your car and makes the subs you own right now sound even better! great design and is very sturdy and well built, only bad thing that happened was that one of the port cylinders popped off because of the intense boom but dont let that stop you from buying it! nothing a little industrial glue cant fix! ITS SOOO WORTH THE MONEY, BUY IT

loud box,built nice

May 28, 2012

Running earthquake 12s with mrx-50 alpine 500 watts mono into 2 ohms, bass is fair for rock music, recommend blocking off all four ports for hard bass to be felt. Just place a five inch wide 3/4" particle board across all four ports, carpet board first though, box will hit hard and sound deep. Ghetto bass for sure!

Decent

March 22, 2012

Good box, but I would recommend chucking the plexi glass, and covering up one port on each side. Will hit just as hard and hit the lows a lot harder and louder. I was the guy below, and yes my alpine type s sounds like type rs in a sealed. It instantly took the breath out of me and im running 275w rms to each.

good but not sturdy

March 15, 2012

This is definitely a hella loud box, got two Alpine type s new models and running 600w rms of clean power. I aint' gonna lie they freaking slam, HARD, but the box is cheap mdf. Screws stripped out from changing subs so much, and i cracked the plexi glass. Get some caulk and longer screws. This box will blow you away, i love it but it doesnt produce much vibrations. It's all sound which was kinda dissapointing, but it's well worth the $ I payed for it!

Seen A Lot

October 16, 2008

There is a good reason you will see this style of subwoofer enclosure a lot. It's because this system is sleek, stylish and works well for a hard-hit bass system. If you have the room and the budget and are looking to impress then look no further.

One of the best products i have bought

August 28, 2008

When i got the box in the mail, lets just say at first i was so excited.lol When i got home Opened the box up i really liked how they packaged it. bubble wrap and foam balls to protect my box. Inserting my speakers into the box was easy and quick. i couldn't believe it. very easy installation. I recommend people buying this box. Buy the box and your speakers separately its cheaper that way to.

Even the crappiest subs can sound good

July 3, 2008

im not a fan of just low base so i thought a this box could give me the best of both worlds and it does. i currently have to DUB audiobahn 12's which are not the best subs but money only goes so far. anyway they make my subs sound amazing hitting all the mid to high rumbles and even most of the lows. i like a louder bass so the lows don't bother me definitely a great box and its easy to work with

Nice lookin bandpass box

August 29, 2007

I just bought this bandpass box for my MTX subs, the box is a step up from a sealed but I think the bandpass tubes leading through the top may not be the best idea. My friend has a bandpass box with tubes leading to the front and it really sounds good. The box has a really good look to it and has pretty good sound quality.
