Repair a blown speaker

It happens to anyone blaring their music at any respectable amount of decibels. Sooner or later you blow a speaker. The cone rips away from the ribbing and you think to yourself "Why the hell do I even spend money on this crap?"

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

Once you have your materials together, begin by threading your needle. Use as much thread as you're comfortable with; you can always tie off your stitching and re-thread your needle. I found it easier to work in sections. Tie a big knot at the end of your thread if this is your first time sewing anything, otherwise use whatever fastening method you're comfortable with.

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.

I got a tiny "rip" on the paper part, I guess that is the "cone"? Can I tape it or put some other material on it and glue it. The opening flaps when the speaker is on, so not too good. I saw under "materials" a coffee filter, but didn't see it's use accept as a possible "material" for cone repair. Am I off base?

um, thts not how you permenently replace a speaker

You're right; but when you need to patch it and make it work until you can get a new speaker this works fairly well. No one said this was permanent, however, I will note that I still use those same speakers and have had no problem since.
