The enclosure is very simple in design and construction, and can be built from one 4 x 8 sheet of material. Since the largest panel sizes are relatively small, I decided that special bracing or joinery was unnecessary and that 3/4" MDF was adequate. Simple butt-joinery construction was used, with everything being secured with yellow wood glue and a few brads. From my experience, using more elaborate construction techniques would only yield very small improvements in performance in this case, and simplicity was once again favored. Since the drivers would all be surface-mounted, I chose to cut out the cabinet holes using a compass and saber saw.

After the enclosure was built, all of the interior joints were sealed with a latex caulk to prevent leaks. The upper portion of the cabinet behind the driver cutouts was lined with 1-1/2" acoustic foam, and the lower portion was fi lled with approximately 1 lb. of Acousta-Stuf per cabinet. Be sure and "fl uff up" the Acousta-Stuf before you put it in the cabinet, 1 lb. should fill almost up to the bottom of the woofer hole.

The cabinets were finished with the Parts Express cherry vinyl laminate, requiring two rolls to do both cabinets. It was applied by hand and the edges were trimmed with the Parts Express standard heavy-duty locking knife (#360-373). When working with the vinyl veneer or any veneer, I prefer to first cover the bottom panel, and then the back, the sides, the top, and then the front.
