How to Make an Xplod 12-Inch Subwoofer Box

By Nichole Liandi

Sony's Xplod subwoofers feature a unique pentagonal cone that provides a large surface area for high-performance bass output. Despite the pentagonal cone, the woofers are built into a more conventional circular basket, so they can be mounted into standard sub boxes with a round speaker cutout. If you don't want to purchase a sub box to mount your subwoofer into, it's a fairly straight-ahead task to build your own sub box to mount your Xplod 12-inch subwoofer into.

Cut two 15-by-15-inch panels for the front and back of the box from the sheet of medium density fiberboard, using your circular saw.

Carve out two 15-by-12-inch panels for the top and bottom of the box from the sheet of medium density fiberboard, using your circular saw.

Cut two 14-by-12-inch panels for the sides of the box from the sheet of medium density fiberboard, using your circular saw.

Assemble the top, bottom and side panels together, with the top and bottom panels overlapping the side panels. The outside circumference measurements will be 15-by-15 inches. Screw the panels together with wood screws and a screwdriver.

Place the front and back panels onto the box. Screw them onto the box with wood screws, using your screwdriver.

Cut a round opening measuring 11 1/8 inches in the center of the front panel. Drill a hole in the back panel, directly opposite the front opening.

Push the end of your speaker wire into the box from the back. Reach into the front opening and pull the wire out of the front of the box.

Connect the ends of the speaker wires to the terminals of the Xplod subwoofer. Place the subwoofer into the opening in the front panel and screw it into the box, using screws placed in the openings of the subwoofer's outer rim.
