Enclosure Guidelines
DS - XS SERIES CALCULATIONS
To work properly, the walls of your
enclosure must be free from flexing
during high sound pressure generated by
your subwoofer(s).
For best performance, always use MDF
(Medium Density Fiberboard) or Baltic
Birch Plywood to build your enclosure.
We highly recommend that your wood be
at least 3/4" in thickness. The enclosure
should be sealed internally with silicon or
glue and secured with screws every 4".
Assemble the box before cutting the
subwoofer hole(s). If the box will be
mounted in a vehicle, it should be
fastened securely using metal "L" shaped
brackets.
To build an enclosure, calculations will
need to be made using the information
found on the following 3 pages.
Remember:
• Use 3/4" MDF or Baltic Birch Plywood
• Use silicon or glue in joints
• Use screws every 4 inches
We at Dual are diligent in checking the dimensions provided.
The engineers, staff and installers provide this information to
make your installation go as smoothly as possible. Errors do
occasionally occur. We highly recommend that you personally
measure your subwoofer prior to installation to avoid any damage.
Please follow the rule “Measure twice, cut once".
