Creating a speaker enclosure from PVC pipe can be an interesting afternoon project that may become a conversation piece. Speaker cones and PVC pipe are readily available and simple to work with. Create as many speakers as you'd like, add them to various locations around the house, and enjoy the time spent creating them. The size of the finished product is something you determine, so let your creativity be your guide.

  1. 1

    Create a speaker template. Place the speaker face down on a sheet of heavy paper and draw around it with a pen or pencil. Use scissors to cut out the circular shape, staying inside the line. Discard the cut-out circle.

  2. 2

    Place the template on a plywood square slightly larger than the diameter of the speaker and trace the circle, staying just inside the line. Cut on the inside of the line with your jigsaw to create the speaker opening. The opening must be slightly smaller in diameter than the speaker or the speaker will fall through the hole.

  3. 3

    Attach the cut out plywood to PVC pipe. Using a 4-inch diameter PVC pipe fitting, such as an elbow, use the silicone to glue the cut-out plywood to the pipe and let dry. This is the mounting surface for the speaker.

  4. 4

    Notch the opposite end of the PVC to make room for speaker wires. Use a utility knife to carve out a small void for speaker wires to pass through.

  5. 5

    Use silicone to glue a flat plywood base to the notched end of the PVC pipe. Let dry. Then pass a speaker wire through the notched out section of pipe and leave it hanging out the top.

  6. 6

    Attach the speaker wire to the speaker cone and insert the cone into the cutout. The speaker is glued into place using silicone caulking. After the silicone cures, your enclosure is complete and may be attached to your sound source.

Tips and warnings

  • Silicone caulk will secure wood to plastic and eliminates the need for screws.
  • The inside diameter of the PVC pipe must be greater than the outside diameter of the speaker cone's inner body.
  • Protect your eyes with safety glasses when using the jigsaw.
  • Protect your hands with leather gloves when cutting with the jigsaw and utility knife.
