BOX SIZES AND BUILDING TIPS
The material of choice for building a strong box is 3/4” to 1” MDF (Medium Density
Fiberboard or HDF (High Density Fiberboard). For a large dual boxes more than 2 Cu.Ft.
adding additional cross bracing using strips of this material is a good idea to help reduce
panel vibration. Don’t use particle board is not very good for speaker enclosures. It soaks
up water like a sponge, is exible and will crumble when you try to screw the woofer in. A
solid bead of wood glue is recommended for joining two pieces of wood together along
with 1-1/4 to 1 1/2” drywall screws or 1-1/2” staples. Remember the glue will be doing
almost all the work once it has dried. A fastener placed about every 3” will hold the box
together good enough until the glue dries. After assembling the box and allowing the glue
to set up, use silicone sealer to make absolutely sure the corners and other visible seams
are perfectly sealed. The sizes below are a guidelines according to our in car testing
and computer analysis. Don’t worry if you box is a little larger or smaller than the below
recommendations the world will not come to an end, the sun will come up tomorrow and
you will probably won’t hear the dierence. Usually a change of more than .15 Cu.Ft. is
needed before even someone with golden ears is able to hear the dierence.
