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.
Ported 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.
7-1/2"
Total Box Volume
The internal volume measurement in cubic feet before subwoofer magnet displacement.
1.21 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.
Height
The height of the item, measured from top to bottom, in inches.
14-1/2"
Width
The width of the item from left to right (side-to-side) measured in inches.
32"
Depth
The front-to-rear depth of the item, in inches. If the item is angled or slanted, this value is the bottom measurement.
16-3/8"
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 (banana clip ready)
Box Exterior Color
The color of the enclosure's exterior/outer finish.
Gray
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
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

I bought this box with 2 12" boss phantoms and later on i bought a 4000 watt Boss amp and then i blew the plexiglass right off out of the screws. Then a few days later fixed box and still worked like a champ, then i blew the 12s.

Put 2 RE SE-X 12's in this box with a HiFonics Brutus amp running about 600 watts and they blew the ports off the box. in my opinion this box is not built very well, but would work for someone that wants a little bump.

I have this box.

June 18, 2010

This box slams so hard. I have two kicker 12's cvr at 4 ohms in this thing. They bolted right in. The plexiglass makes all the difference bro. It's insane. I ou beat everyone. I have a 2000 watt Power Acoustik amp and it takes everything i put at it. I also have a cap and a optima battery. Get this with two CVR's and you'll be sounding good.

Awesome Box!!

March 30, 2010

Ive had a few people in the past tell me to stay away from bandpass boxes. I decided to ignore them. I bought this box and put 2 12in MTX 200RMS watt subs in and plugged it into the amp in my truck (building a system for a friend.) I was VERY impressed with the sound. At roughly 400rms, this thing hits hard!!! Even harder than my 600RMS setup thats in my truck which makes me jealous. Its a fairly attractive box and is built pretty tough. Keep in mind that this thing isn't flexing my roof like a more expensive setup may do but for the money you cant beat it. The only downfall is that the screws that hold the plexi-glass in are just floating in the ports of the box. I came up with 2 missing. I would DEFINITELY recommend this box if you want to save a few $$$.

April 7, 2012

I bought this box bout a month and a half ago and I put two 12d lanzar subs and it was amazing. The power that this box produces with each hit it literaly sucked the air out of me. I have it in a 2004 jeep grand cherokee hooked to a jl split 3000 watt amp and wow great product. Just one problem the plexi glass is starting to break, one screw has stripped itself out. Other then that great box. Recommend it to evryone that wants a great box at a low price.

Great box

July 10, 2008

I got this box to go with my 2 kicker 12's. Sounds great and puts out some nice solid clean bass. Since the kickers i picked up 2 alpine type R's and they wont even begin to fit in the box. But for a predesigned box over the internet it was a great box and deal. Especially with sonics prices!!

Perfect Bandpass Sub Box

January 24, 2008

I have two Type-R 12" Alpine and i put them in this new box and they sounded like 15". My School security told me to keep it down or ill get a ticket next time! I also set off a few car alarms. This box is perfect for anyone how wants a lot of bang for their buck.

January 24, 2008

I have two 12" Fubar's and a 500w rms amp and a infarad cap with this box. i have got to say. this box can take a beating. I can hit 140 db with my setup. the box looks sweet too, my friends say its the coolest box they've seen. one complaint is that the carpet inside the sealed portion isn't secured down well and it is stained in a couple spots, easily fixed though, and i did have to make the hole a little bit bigger to drop my sub into its spot, but it was fun. overall, this is a good box to get if u need to protect your subs and get massive bass at the same time.

I bought this and plugged my two cvr's in to the wall to test and make sure they work. Let me tell you that these slammed so hard it blew the Plexiglas right off. I put it in my car and immediately shattered my rear window and knocked my rear door open. Slams dude at least 190db.

Sound Vs. Flashy

April 30, 2008

Ok I'm a big fan of bandpass boxes because they can make the best out of cheap subs or take advantage of quality ones. Recently, I gave my other bandpass box (Adrenaline ADRBP12) to my step brother, because when i wanted to upgrade my subs they wouldn't fit because the mounting depth was too small! Plus i noticed the bass was loud but some of the low frequencies were coming out real muddy (i hate that). Those flashy chrome Plexiglas loaded boxes r nice but i don't recommend them if you ever plan to upgrade to better subs with bigger magnets (i.e 45oz to 140oz) I got 2 spl dvc 12s on a 1200watt amp bridged in my 07 Yaris...the bass hits so low and loud its amazing. The bass goes through me and my seats rumble its crazy. Nowhere near the performance of my old box and subs. A++

nice box, putting the subs in was a easy. iv got two Volfenhag ZX-4812 subs, with two Kenwood KAC-8103D amps, hits hard. i cracked the plexy pretty good, and one of the screws was blown louse. might try adding more screws or just a thicker piece if your using some hard hitting subs
