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".
