How to Repair Speaker Cones

By Techwalla Electronics Editor

Speakers can be extremely expensive investments in your total sound system. You can repair a small tear in a paper speaker cone yourself using very simple ingredients and prevent the large expense of sending the speaker out for repair or replacing it entirely.

Step 1

Take some tissue paper and cut it into a few pieces that are a little larger than the tear in the cone. You'll need about 10 pieces of tissue for each tear. Use craft tissue paper that you can purchase from a craft store or a gift shop.

Step 2

Put some white school glue in a bowl. Dilute the glue a little with some water; stir in a small amount of water at a time until the glue is soupy and easy to work with. Don't dilute too much or the glue may not hold when dried.

Step 3

Carefully soak the strips of tissue in the diluted glue. Be careful not to tear the tissues when handling.

Step 4

Apply the glue-soaked tissues one at a time. Allow each piece to dry to a tacky consistency before adding a new layer. Apply three to five layers of tissue to each side of the cone.

Step 5

Let the tissues dry overnight in a well-ventilated area.

Tips & Warnings

  • Getting the consistency of the glue right is a little tricky, so it would be a good idea to practice this repair technique on a dead speaker cone first.
  • This repair trick only works with paper cones. Rubberized cones require a special repair kit that you can order online, or they need to be sent to a repair shop to be repaired.
