You can build your own subwoofer enclosure. (speaker image by Byron Moore from Fotolia.com)

A subwoofer box is needed for any subwoofer. Oftentimes, subwoofer boxes are not the correct size and a custom box needs to be built. You can build your own subwoofer box using simple tools. Subwoofers are designed to produce low-bass sound waves. A subwoofer box not only houses the speaker, but offsets the sound waves as well. Building your own subwoofer box will save you money.

Instructions

  1. 1

    Measure the space you would like to place your subwoofer box. Determine the size of the subwoofer box.

  2. 2

    Develop a cut list. Build the subwoofer box out of 3/4-inch MDF. The sides will need to be the height and depth you want the subwoofer enclosure. The top and bottom of the box will butt-joint into the sides so you must subtract 1-1/2-inches from the length of these parts. The front and back section will be the length and width you want your subwoofer box to be.

  3. 3

    Draw each part on a sheet of graph paper to scale. This will allow you to determine how many sheets are needed and the best way to cut out each piece to avoid wasting any material.

  4. 4

    Draw lines on the sheet and cut out each piece using a circular saw.

  5. 5

    Apply a small amount of glue to one edge of the top and bottom. Butt-joint these pieces into the sides and fasten them together using a power drill and 1-1/2-inch grabber screws. Place the screws about 3 inches apart.

  6. 6

    Apply a small amount of glue to the opposite edges of the top and bottom and attach the other side using a power drill and 1-1/2-inch grabber screws.

  7. 7

    Place a line of glue around the edges of the top, bottom and sides for the back to mount. Fasten the back using a power drill and 1-1/2-inch screws.

  8. 8

    Cut the tip off the silicone and puncture the seal. Place the silicone inside the caulking gun.

  9. 9

    Apply a large bead around each seam on the inside of the subwoofer box. This will ensure the box is airtight.

  10. 10

    Place a small amount of glue around the front edges of the box. Attach the front section using a power drill and grabber screws.

  11. 11

    Place the template onto the subwoofer box that came with the subwoofer. Draw a line around the template on the box using a pencil. Repeat this process to the other side of the box for two subwoofers.

  12. 12

    Cut out each circle using a jigsaw.

  13. 13

    Attach the subwoofer to the box using the screws provided and a power drill.
