How to Re-Edge Your Speakers

Repair your drivers and save money

A good set of speakers is one of the few hardware items you can buy that can last several decades.  While the speaker cone is pretty reliable, you will eventually have to service the foam that surrounds it.  Over time, the foam becomes brittle and flakes off, or (in my case) you have some pesky children who think it’s fun to pick all of the foam away.  In my case the destroyed speaker was a Kenwood SW-300 subwoofer, which had the 10″ cone demolished.

Regardless of how you got to this point, you have two obvious choices: either buy a new speaker or replace the entire driver assembly.  The hidden option number three is to repair the speaker yourself.  As long as the paper cone isn’t damaged then really all you have to do is replace the foam and gaskets around the paper cone.  This could save you a lot of money, especially the bigger and more expensive your driver is.  In my case, I could not locate the specifications on this speaker, so there was a possibility of a mismatch if I chose a third-party driver.  The exact matching Kenwood cone cost over $100.  For around $15 and a little time I was able to repair my driver and salvage my expensive subwoofer.



All the parts: Busted driver, replacement foam, four paper gaskets, a brush, and Elmer’s Glue

Doing repair on your speaker may be intimidating to those that aren’t experienced with such things, but it is very easy.  Let’s face it; this isn’t rocket science and you don’t have to do anything electronic.  If you’ve ever glued popsicle sticks onto construction paper in kindergarten then you’re more than qualified to re-edge your speakers (but you may need help with the Safety Scissors).
