Never fear, this instructable will show you how easy it is to repair a ripped cone. The great news is you won't even need any strange materials for this fix:
- Sewing thread, one (1) spool. Pick a color that closely matches your speaker material, unless you plan on being meticulous in the following steps. I used a cotton thread, but the type shouldn't be a major factor here.
- Sewing needle, one (1). Use as small a needle as you're comfortable working with. If this is your first time, don't fret too much, just don't use a needle that's so big it could tear the cone even more.
- Elmers General Purpose Glue or equivalent, one (1) bottle.
- Glue spreading apparatus, one (1). Finger, gloves, paper towel, pencil, credit card, use your imagination.
- n speaker(s) to repair.
- Just a little patience.
Step 1: Thread and Stitch
Push your needle through the cone, approximately 1/8" to 1/4" from the outer edge. You may start from the top of the cone or the underside, I found it easier to start from the underside going up. Pull your thread tight, and then push down through the ribbing, near the inside edge. Keep the stitch tight. Repeat this until you have gone all the way around your cone or have run out of thread (in which case, thread your needle again and start where you left off by just overlapping the last stitches). Tie off and cut the thread.
Repeat as necessary for each speaker.
