Features
- SINGLE 12 INCH VENTED SUBWOOFER ENCLOSURE: The Bbox 12 inch single vented subwoofer box enclosure is designed for optimum bass response and low-frequency reproduction which is ideal for lower profile sound quality subwoofers. Get the most out of your vehicle's subwoofer with a truck sub enclosure designed for power and quality.
- SPECIAL FORMULA: We use Aliphatic wood glue on our 12" subwoofer enclosures to ensure an airtight seal between all MDF parts. Each 12 inch subwoofer box also gets a second application of glue around all internal joints after the final assembly.
- HIGH GRADE MDF: Our subwoofer box enclosures are built with a durable MDF that is 5/8" thick for solid frequency response and accurate music reproduction and we use a CNC Miter to ensure an airtight fit for your powered subwoofer. Our Dado design and construction offers a precision fit for our car subwoofer boxes & enclosures, which ensures a rattle and noise free environment.
- AIRTIGHT RECESSED SIDE PANELS: We use quality materials like our special aliphatic resin wood glue and brad nails from a pneumatic nail gun to create a tight hold on the MDF parts during the glue drying process to ensure that our subwoofer boxes have an airtight no-leak, no-rattle air chamber improving the overall sound quality of your sound system.
- ENCLOSURE DIMENSIONS: Since your subwoofer box or enclosure most likely goes into the boot of your car, checking their dimensions is highly important. Enclosure Dimensions Mounting Depth:13.875, Sub cut out: 11.125, Height: 13.625, Width: 16, Depth: 17.375

Was a perfect fit in my Grand Marquis to have a small subwoofer and the price is actually good and it seems quality enough for what I'm doing. The sub was finicky to put in but that's not the boxs problem. The main and really only problem I ran into was the included terminals and wire gauge used on the terminal case. Waaay too small for my comfort level on a 500 watt rms subwoofer. So I had to take the terminal case on and solder on larger wires. After that it's functioning as I prefer and is the perfect size for the space as seen in the pictures if I post any.

This is a reallly good box for the price, can't go wrong. As another reviewer said, the description is a little misleading as part of the construction is 3/4" mdf (as advertised) and part is only 1/2" mdf. I sprayed the interior with plastidip to sort of thicken it up and prevent vibration, although I'm not sure if that was necessary, it does seem well built and glued together. Porting frequency seems a tad high (see UPDATE below), maybe 45 or 50hz or even higher? ...but it's easy to lower the porting frequency with a wadded up old tshirt or a pool noodle as another reviewer suggested. In an automotive application it might be low enough, for home theater or dnb or hiphop shows maybe experiment with a pool noodle in the port *grin*. Overall, this is a fantastic box, well built, pretty compact, a real steal for under $80 shipped. ~~~ Note you will need a drill bit for speaker holes, some screws for mounting, some wire to connect your sub to the terminal. UPDATE: Confirmed the porting frequency is much too high, added it at a show to a KV2 dual 15 (one of the best sub setups) and this was literally canceling out the lowest notes of the KV2. We finally shut off this sub. BUT, that is an easy fix, partially obstruct the port with something like a pool noodle OR if you are near a wall place this sub an inch or way from the wall facing the wall. This will effectively lower the porting frequency and it won't cancel out the 35 hertz notes from your other speakers. Still great for the money! editagain: In my pic I'm using "Allstar - ALL14100 Black 3' Roll Bar Padding" to mostly obstruct the ports and the porting frequency after doing that is about 31 hertz. MMM mmmmmm (I'm guessing it was 45 or 50 hz before that, much much too high)

Very nice enclosure. Sturdy construction, looks well sealed. The interior volume is 0.83 cubic feet or about 23.5 liters, which is just about right for my Polk Audio DXI124 that I plan to run in it. Ordering the box from Electronic express was a different story. The price was attractive, but they apparently were out of stock on this box and send me the wrong box that I had to return and then made me wait about 2 weeks until they received a new shipment of these boxes. The customer service via email was not helpful about order updates; calling them worked though. Overall, I am satisfied with the box.

Box is just ok. It sounds good, but I had a couple of issues. When I got the sub mounted, I pushed the cone and there were severe air leaks in the box. The first leak was the extremely cheap terminal on the side. It was free flowing air through the cup, mostly the spring terminals themselves. I swapped it out with a plate, but still had an air leak. I finally figured out that they had a 3/4" datto cut for the side board, but the scrap board they used wasn't quite 3/4", so they laminated it with another board that looked like 1/8" thick. When the sub would depress, the air would go into the cutout for the terminal cup, go between the layers of wood, then come out from the joint at the corner. I never got it sealed 100%, but it is close. It really does have a solid 1" mdf face board, which made for a super sturdy sub mount and homemade speaker grille mount.
