BUILDING THE ENCLOSURE
∙Determine the dimensions of your enclosure.
∙Be certain the box you have designed will fit into the location you have chosen. Sometimes making a cardboard box with the same outside dimensions is helpful.
∙Use 3/4 inch thick Medium Density Fiberboard (MDF) or High Density Particleboard. It is preferable to cut the wood with a table saw to ensure straight, even joints. If a table saw is not available, a circular saw is acceptable.
∙Use a “T” square to verify precise right angle gluing.
∙Use a high quality wood glue and air nails or wood screws to assemble the enclosure. Elmer’sâ woodworker’s glue and Weldwoodâ work well. To guarantee an airtight box, seal each inside joint with silicone sealant.
∙For Sealed Enclosures, stuff the chamber with
∙For Vented Enclosures, staple 1 inch thick fiberglass insulation or Dacron to all walls of the enclosure except the baffle to which the woofer is mounted.
∙Use the supplied gasket to seal the woofer in the enclosure and eight(8) wood screws or
∙Use
