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