dX Subwoofers—More Bass, Less Space The dX Series of subwoofers use the latest technologies and highest quality materials to provide you with the best bass response and greatest reliability possible. The dX subwoofers have been optimized to give the kind of skull-collapsing performance one would expect from huge enclosures in boxes that take up a fraction of the trunk space. Some of their design elements are: Attach your receipt here and file for future reference. It may be required for warranty service.
Who Is Going To Build Your Subwoofer Enclosure? Since the subwoofer enclosure is so critical to getting the best performance from your dX subs, you should ask yourself the following questions: 1. Do I really enjoy working with my hands? 2. Do I have good woodworking and mechanical skills? 3. Do I have, or have access to, woodworking and electrical tools? 4.
dX Series 6 Premium Performance Loudspeakers Usable dimensions (Minus 1.5 inches)=______inches (Minus 1.5 inches)=______inches (Minus 1.5 inches)=______inches Usable volume=________cubic inches Usable volume=________cubic feet Multiply your usable Width x Height x Depth. The product will be the usable (internal) volume of your enclosure in cubic inches. Divide this number by 1728 (the number of cubic inches in a cubic foot). This will give you the internal volume in cubic feet.
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.
