This box is offered for hobbyists
who love to experiment. Since there are so many ways to load it, you
should be able to find at least one that works with your woofer -
regardless of the driver specs. (Theil&Small)
The above illustrations depict only a few of the many ways this
enclosure can be loaded. You may also experiment with running one of the
woofers as a passive radiator for increased gain. (Higher Q)
The ideal woofer selection if you going for the lowest bass would be a
sub-woofer with an fs around 20 Hz, and a Qts less than .38 and a
minimum VAS of 10 cubic feet.
You can sale the plans up 18 inch woofers or down for 12 inch woofers.

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 exactly 1/2 sheet of 48 x 96 inch plywood, MDF or high density
- 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.
- 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. If
you're into box carpet and liquid nails to hide your joinery, and demand
the best performance consider purchasing one already built by
Decware. We use CNC machines and build the cabinets more perfectly
then is possible to do by hand.
- 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
