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.
2.1 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.

Binding posts
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.
Tuning Frequency
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.

Port Details

Number of Ports
The number of ports the enclosure has.
Tuning Frequency
Port Length
The length of the included port tubes. Many tubes are cardboard and may be cut to the length recommended by the sub's manufacturer. Check your product's owner's manual for the recommended port length for your sub.

Best bandpass enclosure

November 7, 2011

Ive had this exact style of bandpass enclosure years and years ago and its amazing what it can do. I bought this one and have had it for about 2 years now. Solid box, performance is insane. I had a single ppi pcx 124 loaded and on an alpine mrp m500 and this thing just crushes. Turned a small chip in my windshield into a 1ft crack, rattles everything. The bad thing about it is you cant fit a very large sub with a big magnet. I tried to fit a RE audio in it and it will not fit. Buyer beware, make sure to do your homework and find the right sub.

Works great

July 24, 2012

First impressions... the terminal cup is crap, the plexiglass is a bit too thin, and there is some exposed MDF(without paint) in the port. Oh and the carpet on the inside is only partially glued in. So after some gluing and a bit of black paint this box looks awesome.

Performance wise, this thing is a beast! I've got 1200rms pushing my SPL and just switched from a sealed box to this one. It is so clear, and so intense, I really can't believe it.

Great quality built box but not so great sound

June 27, 2012

I purchased this box as a present to my girlfriend for her new 12" alpine R. Me knowing that she probably wouldn't tell a difference in sound quality from a bypass box to a ported box, I purchased this box. It looks great and had the nice plexi glass front I assumed she'd be very happy but when we received the package it was humongous! I know they give the dimensions but never thought itd be that big. Again it looked great and the speaker fit fine. I got everything wired up and started to tune the amp with her car speakers, trying to get that well-rounded sound but never could with this box. It would hit so hard with a specific sound frequency but when it got to high or low bass there was no bass. I would talk to people that knew about systems and me knowing a good bit about them would ask questions and let them hear. Sometimes they said it was the amp not having enough power but that was just ludicrous. The amp we used was an alpine m500 and if you owned that amp you'd know it had major power. A week later I purchased another box, a Polk audio ported box. After installed the speaker and bass came alive. It almost has heart stopping bass! Now I don't like bashing products unless they deserve it but this product wasn't bad for the price. Just didn't work with my girlfriends system. It was my fault for thinking that if it looked nice maybe it'd sound nice but that wasn't the case.
