By looking at the chart at the end of the technical sheet, you find that this usable volume is slightly more than double the recommended volume for a single dX10, in either a sealed or vented enclosure. Assuming that you will be using a pair of woofers, this will work out well.
If you are using a single subwoofer, you can cut your width in half. Since we will
be using a pair of dX10 subwoofers, for our sample enclosure, we now need to determine the center divider displacement. This can be figured out by multiplying the height x depth x thickness of the divider (in our enclosure the thickness of the divider will be the same as the rest of our enclosure, 3/4") and subtracting that number from the total usable cubic inches.
You now have all the dimensions you need to begin cutting out your wood. The illustration on page 7 shows a diagram of the enclosure with all the panel sizes that need to be cut.
After you have cut all of the wood, it’s time to start assembling your enclosure. Before you assemble your enclosure there are a few things we recommend doing. You will need to cut out the hole for your Dynamic Balance® subwoofer and your terminal cup, and

wood glue in combination with wood screws for the strongest joint. We also suggest that you use one screw about every three inches along the seams of your enclosure. Assemble the enclosure as shown in the above diagram but leave one side off. We suggest that you leave off the baffle board, this will allow you to seal your enclosure more easily, and an
One last thing you could do to your enclosure before installing it, is stuff it. The primary reason for stuffing an enclosure is to “trick” the woofer into thinking that the enclosure is larger than it actually is. You would want to do this if you build your box smaller than the recommended size. By stuffing the box you can build the box as much as 10% smaller than recommended, and achieve the same net result as the full size unstuffed box. The easiest way to do this is to use dacron pillow stuffing. It can be bought from craft stores fairly inexpensively. The rule of thumb for “stuffing” your enclosure is 1 pound of dacron per cubic foot. When putting the Dacron into your enclosure, do not pack it in, rather place it evenly around the inside the enclosure. When stuffing a ported enclosure it is important not to obstruct the port or the vent on the back of the sub

Although your new dX subwoofers were designed to work in a wide variety of enclosures and configurations, we have included only the most popular ones. For more enclosures and configurations, please contact your local authorized Polk Audio dealer. We hope that this manual has helped to take the mystery out of designing an enclosure for your new Polk Audio dX Subwoofers.
