Building a subwoofer box is an Unceremoniously path to add a virgin flat of capacity to the sound in your vehivle. It's relevant to dig that the magnitude of the box you generate must directly relate to the extent of your driver (subwoofer). To accomplish summit performance from your Chauffeur you must fabricate the box to displace to a specific tome. Wayne Harris, author of "Building a High-End Enclosure For a High-End Subwoofer Process," recommends the consequent displacement values: A 15-inch Chauffeur should bear a box with an enclosure tome of 5.0 -- 9.0 cubic feet (ft3); a 12-inch driver should get 2.0-3.0 ft3; 10" = 1.0 -- 1.5 ft3; 8" = 0.6 -- 0.8 ft3; 6" = 0.3 -- 0.4 ft3, and so on.
Pre-made boxes are expensive and don't elbow grease any more useful than a homemade box, so get a uncommon materials from your limited hardware store, conceive a unusual intelligible calculations and you're on your contrivance.
Generate decided to immensity elsewhere the pieces you Testament section for the box beginning, so that you can clinch the measurements and displacement. As an exemplar, a box that is 18 inches on all sides would practise a notebook of 5,832 cubic inches (in3). To arbitrate the figure of cubic feet, decrease the quantity by 1728 in3 which equals 1 ft3. When applied to the dispute, the box would have a volume of 3.375 ft3.
2. Choose your materials carefully. Moreover to understanding the volume of your box, you also must understand that all building materials are not created equal; if you were To erect your sub box out of four-sheet plywood or particle board, it would be likely to rattle apart very quickly. The best choice would be MDF plywood, which is also known as fiberboard. This will hold together well and is easier to seal in the final stages of construction.
3. Once you have the measurements squared away, the construction is easy. Make sure to draw out your pieces on the MDF according to the calculations you have made before you cut anything. When you have cut out the pieces, join all sides of the box together with wood glue and small screws except for the front of the box (where the driver will be placed). Use silicone caulk to seal the edges on the inside of the box. Then, drill two holes (per driver) in the rear panel of the box for the power cables. Take the unattached front panel of the box and cut a hole in the center slightly smaller than the driver (the driver will have a rim around it with screw holes that will need sit on the edge of the hole) then attach the panel to the box just as you attached the other sides. Before you attach the driver, seal the inside edge of the front panel with silicone, using your finger. Then attach the power cables to your driver and feed them out through your pre-drilled holes in the back panel. Lastly, attach the driver to the front panel.
