How to Build a Ported Sub Enclosure

Save

A ported subwoofer enclosure has one attribute that sets it apart from other types of sub enclosures--volume. The design ensures you'll hear lots of strong, low bass when you crank up your system. The size of a ported sub enclosure varies, depending on the size of the speaker. Follow these guidelines to build a sub-enclosure that'll bring out the bass.

Things You'll Need

  • MDF board (3/4 inch) Circular or table saw Wood screws Drill Jig saw Terminal cup Port tube Box carpet Carpenter's wood glue Silicone caulk Glue gun
  • Determine the size of your ported sub enclosure. Every subwoofer requires a specific volume of air (box size) for proper operation. Follow the requirements for the diameter and length of the port tube used in your ported sub-enclosure. Note the volume requirement. Draw a few designs for your box, taking into account the amount of space in your car and the size of the sub. Multiply the length, width and height of the enclosure in inches, then divide the resulth by 1,728. This will be the volume, in cubic feet, of your box. Modify the dimensions, if necessary, to come up with a figure that matches the sub's specifications.

  • Cut out panels for the front, back, bottom and rear of the box using a circular or table saw. Use 3/4-inch medium density fiberboard (MDF)--it's strong and vibration resistant. In the front panel, cut out an opening for your sub using a drill and circular saw. Make sure the sub fits snugly into the opening. In the top panel, cut an opening for the port tube and check the size. Using wood glue and wood screws, put the panels together.

  • Use your circular or table saw to cut two end panels for the box. In one panel, make an opening for your terminal cup. Mount the end panels to the box, using wood screws and glue. Seal all the joints with silicone sealant to ensure a tight, leak-free box.

  • You may put box carpet on the box--use your glue gun to attach the pieces.

  • Put your port tube into the opening on the top of the box, holding it in place with glue. Now screw the terminal cup in place with wood screws. Connect a piece of speaker wire from the back to the terminal cup to the terminals of the subwoofer. Put the subwoofer into the opening and secure it in place with wood screws.
