NOTE: Works with 1 or 2 twelve inch woofers.
This is the correctly designed way to scale up our famous 10 inch Deathbox for use with 12 inch woofers.
As you can see it is not scaled at all, but a different design using
the same technology. This maintains the killer ratio of Size vs. Bass Output that makes the design
so successful. The difference between this 12 inch Deathbox and
the 10 inch is increased low bass extension and SPL. After all if
you're going to try to scale up a 10 inch Deathbox you have to get
something in return for that extra space!
Like it's little brother, the new 12 inch Death Box is easy to build.
It has a self sealing removable access lid eliminating the need for gaskets.
Designed for single or compound loading of 12 inch subs, it features a
removable insert making it easy to install the woofers, and tune the
box. And of course don't forget, the DBK212 will work with
most car audio 12" sub-woofers* and can be tuned AFTER BEING PLACED IN
*Free-air woofers excluded
MAX: Bass from 14x14x32 inches of space.
For those of you who are not familiar with this box design, it is quite
simply the most quality bass you can get from this amount of space
(14x14x32 inches). It fits in trunks and hatch backs with ease,
but more importantly it works anywhere you can make it fit!
Unlike boxes that sound OK in the garage and then have no bass when installed in
your car, the DBK-212's self loading design ensures serious low
frequency output in literally every vehicle you can cram one into.
Besides great frequency balance and extra low bass, this box can be tuned to sound the way you want it via a movable
baffle assembly. You just try it in different positions during
your install and pick the one that hits the hardest!
The design also works with the majority of car
audio subwoofers designed for small ported or sealed boxes. It doesn't
care if it's a Rockford, MTX, Apline, Polk, or any other brand of
woofer. It just works.
Like the original ten inch version, this Deathbox
will more than double the power handling of whatever woofer you put
inside it. In fact, the technology that makes this box so
devastating is explained rather well on the DBK10 Deathbox video
below. Remember, this Deathbox is just a larger version of the
DBK10 so all of the technology that makes them work is the same.

can be slid up and down inside the box letting
you tune it by ear while music plays.

HOW TO BUILD ONE YOURSELF
design also works well in the home for either audiophile use where
speed and accuracy are a must have, OR for movies where these same
qualities just make everything sound more real!
- SKILL LEVEL: This is an easy box to build provided you have a good table saw and can make accurate cuts.
- TOOLS NEEDED: Besides a table saw
(with sharp blade) you will need clamps, carpenter's wood glue, a
sander (belt sanders work well) and a drill.
- WOOD NEEDED: The box can be built
from less than one sheet of 48 x 96 inch plywood, MDF or high density
particle board. Below is a cut-sheet illustration showing how each panel
should be laid out for cutting:
- TIP The trick to assembly is to
construct the insert first. Then wrap the side panels around the
insert and install the bottom panel. This way the insert will move
inside the box with a perfect fit.
- SCREWS are typically only used to
fasten the removable top (lid) so that the woofer can be
accessed. If you properly build the box with wood glue and clamps,
nails are not needed as the glue becomes stronger then the wood
itself. If you have an air nailer, you can use 2 inch finish nails
to hold the panels together in place of clamps while the glue dries.
- FINISHES: The most common
way to finish this cabinet is to paint it. There are tons of
finishes available that can make the box look like anything from rock,
to marble. Also you can use real wood veneer for a completely
professional look in the house.
- WOOFERS: The design
makes it compatible with 100's of different 12 inch car audio woofers
that work in smaller boxes. Even an inexpensive woofer will see
double it's rated power handling in this enclosure and sound great doing
- JOINERY: The quality of your cuts
determines the joinery or fit of each panel. Quality joinery is a
major part of the distortion free performance of this box.
- WIRING: Since this box can
be pointing in any direction other then face down, no official back or
front have been defined. We recommend soldering a pair of stranded
16 AWG copper wires to the woofer terminals and run the wire out
through the port opening. Make it long enough to connect directly to
your amp. If you decide to hide the wire, you can drill a small
hole through one of the sides of the box and seal the wire with caulk
where it passes through the hole. Terminal cups leak air and are
