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.
Vented / Ported
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"
Total Box Volume
The internal volume measurement in cubic feet before subwoofer magnet displacement.
3.4 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"
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.
17"
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.
1
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.
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
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.

Substandard Quality

February 24, 2012

I bought this enclosure and was disappointed. My 1500w system with two 12" subs kick so hard that the walls of the enclosure vibrate as if they are going to come out of its joints. It results in a loud vibration noise. Would not purchase again.

not the best

May 24, 2012

This box plays the notes amazingly. From high to lows, it will slap you in the face and keep coming 'til you can't take it. But like the guy before me, the walls flex as if they are goin' to blow. I have 2 Kicker CVR's in this, and the first week was great. Then, all of a sudden, I heard a vibration. So I popped my trunk, and found a line of saw dust on my trunk floor behind the sub box. Looks like the back wall was literally blowing out and creating dust where the nails are. So, I had to screw a bunch to stop the rattle, but it still bounces, and isn't very sturdy like the other walls. Very flimsy. Not too happy. Would not purchase again.

I put polyfill on the walls inside and it is overall a great box, very sturdy strong walls unlike the previous comments, the box looks great and my two 12'' infinities sound beautiful in it thank you sonic.
pros: great looking great sturdy box

I bought this for my son on his 16th birthday... He was greatly surprised it fit perfectly behind the seats of his SL 500. The workmanship on this box is great and I would purchase this again.

Terrible Quality Box!

December 22, 2012

The box wasn't even glued together on some parts...
The wood was some of the lowest quality wood, it compared to particle board.

Had to get a new box after 3 weeks of use because the walls vibrated so much and it sounded terrible.

You get what you pay for with this box.

beginner box

September 2, 2012

im running 1200 true watts to 2 alpine type R's the power from my subs rattled the walls loose and made a terrible noise...if you are running 500-800 watts this would be an excellent box, but its not built strong enough to handle more power than that.

Loud!

April 7, 2012

This box hits hard and fits my 2 12" kenwood performance subs well. I'm running a 1800w kenwood 9105D amp (900rms @ 2 ohm) to the 2 subs (400rms each). Shakes the entire car, even with sound deadener that is literally on every inch of the trunk and most of the interior. Unfortunately, the 2 terminals are poorly designed for this box I think, I had trouble with them right away, the subs shook the nuts off of the bolt holding the wire almost immediately, so if you notice any problems w/ power, check there first. Otherwise this is a great buy.

Excellent Box for Pioneer Premier Champion Pro Series

March 17, 2012

I bought this box, and I was skeptical on how they would sound with my brand new 12" Pioneer Premier Champion Pro Series subs (TS-W3002D2), and let me tell you thing things slammmm! The lows are amazing and the highs are alright. I'd say if you're looking for that deep bass with these speakers, this is the box to use. The highs don't hit extremely loud, but you can still hear them pretty well. I was looking for deep bass anyways. Talk about severe trunk rattle. Spend the $80 on this box, it'll be worth it, especially with those subs.

this box is awesome

March 7, 2012

I bought this box for a Kenwood system and am extremely impressed. It was not as big as you would think so it will fit in your trunk. For the price you can't beat it for a custom box. Well worth the price and then some if you want the best from a system go with this box or any profesionally ported box the only con is the terminals the plastic nuts make me nervouse and they would be easy to lose. SonicElectronix got you covered for sure if you don't know what your doing ask them for what you think you want it to sound like and they will get you squared away. A huge thanks goes out to SonicElectronix. They know how to put a system together that will be compatible for you.

Better than expected.

February 18, 2012

Put this box in my Durango and it is LOUD. I'm running 2 Boston Acoustics G112-4 on 400W RMS. Its like the box was made for those speakers. I expected the box to be nice for the price but it competes with some custom boxes Ive had in the past. If this box matches the specs for your subs, don't hesitate.

The only cons about this is the terminals are plastic and can become loose. This however has not effected the sound quility. This box is very heavy duty and sounds outstanding. It matches my interior and was impressed with the craftmanship. It smelled freshly crafted after opening the box!! love it
