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.
Sealed
Number of Subs/Speakers
This value represents the number of speakers or subwoofers that the enclosure accommodates.
1
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.
11.25"
Total Box Volume
The internal volume measurement in cubic feet before subwoofer magnet displacement.
1.0 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.
Height
The height of the item, measured from top to bottom, in inches.
12"
Width
The width of the item from left to right (side-to-side) measured in inches.
16"
Depth
The front-to-rear depth of the item, in inches. If the item is angled or slanted, this value is the bottom measurement.
13"
Wood Thickness
The thickness of the wood the enclosure is made of, measured in inches.
3/4"
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.
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
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.

AWESOME BOX

September 13, 2006

I have a DUB MAG 1200 Sitting in this box and all I can say is that this box hits HARD!!. Now first off for those of you who don't know, you are actually going to get the best base response with a sealed box and I would definitely recommend this one. It is also not too big and is good for about 1.5 cubic feet of volume. Also I have a 3000GT which is notorious for it's shallow trunk and small amount of trunk space and this box fit easily with room to spare!!! So this is definitely the box for you if you are looking to save space and/or want to have excellent sound.

This is a well built box. Very sturdy. Accidentally dropped a few times and it didn't even phase it. I used it with a 12" Alpine Type R and it did ok for being sealed. Of course after I went to a ported box, I got a lot more output out of the sub.

Sub Box, 6 months later

March 22, 2012

Overall I've been very happy with this box. It seems pretty responsive and seems to be sealed properly. Though I'd still highly recommend it, I have had two minor issues with it:
1. The first day I had it hooked up my bass kept cutting out. Took a look and the back side of the terminal (on the inside of the box) were loose, creating a poor connection. Simply tightened it up with a screwdriver and haven't had issues since.
2. I just noticed that the carpeting is starting to pull away in 2 spots. Granted, it's pulling away where I usually grab the box to move it, which I do fairly often.

Overall though, I'd recommend the box if you're needing a sealed, compact box for a 12" sub.

November 21, 2012

I really liked the box. Bass was really tight and precise. Pros: tight bass and hit real hard sounds good in SUV also it was a little small for me but if you are tight on space as i was, this box is the one for you. Cons: Little small. It will slide around a little, so take my advice and mount the box down or you could velcrow it to the carpet other than that it rocks

This was a really great box, it was well built and was airtight. Carpeting was very nice. I used this for an Alpine Type R 12" was all I could have asked for. I have now upgraded to a ported box, and of course it's a lot louder than this but hey, it's ported. I would totally reccomend this box to a friend.

Sonic Sub Boxes 1SL12-1.0-BLACK

June 17, 2010

I love this box! I have owned and tried several variations of single 12" enclosures and for my needs this was the most versatile. Being as I am an adult with a family and a life I cannot completely dedicate space for the 'system'.I can throw this in the back seat or in the rear hatch.If I'm bringing home the bacon, eggs, milk, etc from the store I can always move the enclosure if needs be and don't have to strain or unbolt anything. The sound is tight and punchy. Its small and movable. The carpet is good quality and the construction is top notch! The binding posts leave a bit to be desired for me, but you can upgrade them easily yourself if you so choose

April 20, 2009

I love this box. Bass sounds loud, clean, and punchy. The hook ups were high quality, as were the seals. Just be sure you get a grill if your sub doesn't come with one. I didn't, and taking the whole thing apart just seems like a pain. Also, get baffling if you want it.

I would recommend this product to any of my friends for the simple fact that it was inexpensive. They usually say, you get what you paid for, but in this case you get more than what's expected. I've been running 1 Alpine Type R 12" in this enclosure and could not be happier. The box is on the smaller size but is perfect for allowing my subwoofer to maintain that tight and accurate bass. I am for sure going through Sonic Electronics for future subwoofer enclosures!

I bought two of these to house my Infinity Kappa Perfect 12d VQ subs. They fit great and looked good. One of the boxes has a slight leak of air when in use from the top where they "glued" the corner...this I will fix later with a sealer from the inside. Other than that...worked great!

good little box

January 3, 2012

The box is perfect for the simple enclosed box setup. The volume is small, so I just added some polyfill and now the box makes the sub's bass sound clean, with a good solid punch. So having polyfil will help with subs that need the cubic vol, if getting this box.

Great performance, great cosmetics!

June 5, 2011

When I purchased a 12" Alpine Type R sub, I looked up the recommended size to mount it into. I decided to go sealed for sound quality (tighter and punchier bass) over ported for loudness, and went with this box from SonicElectronix because of its low price. The box looks great, feels solid, and best of all, my Type R POUNDS in this thing! I am very pleased with my purchase.
