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.

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.

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.

3
Carefully soak the strips of tissue in the diluted glue. Be careful not to tear the tissues when handling.
-
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.

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.

If I repair the speaker like this, would this noticebly change the sound quality? And having tissue stuck to the speaker would make it look really tacky. But thanks for the helpful instructions.

I would not suggest this. White glue becomes hard and brittle when cured. The vibration from the speaker will likely make the above a regular maintenance routine.

soak in , then used a shapie to color the tissue black to blend in somewhat to the speaker, put the speaker back in the cabinet and gave it a test run for 30 min ( low to near max volume) so far it holds and sounds like great,no buzz nothing. i would reccommend giving it a try since all you got to lose is about 5 dollars for the glue and tissue. -

you make a point spex, if its a long tear then the cone has to be replaced. however i dont think that applies with small tears... One of my 10" speakers for my gallien krueger got a 1.1/2 tear due to rough shipping . I across this article and give it a try since the same logic applies to fixing a surfboard or a hole patch on a vehicle with paste and screen.... why not tissue and glue to a paper cone? now Instead of dipping the tissue into the dilluted glue ( because i was worried that too much glue will make the patch too hard and mess up the sounds comming out from the speaker) i just slightly applied the d-glue to the edge of the tear which pressed back together and left a slight ooze of glue for me to tear finger pieces of tissue and press the pieces together ( from both sides letting the glue soak into the tissue. after 4 hrs i used pliers to pick of pieces of tissue that didnt...
