Shaggy Posted September 14, 2012 Share Posted September 14, 2012 Anyone tried re-coning a blown speaker themselves using one of the commercially available kits? Being the cheapskate I am I'm tempted, but can see me making a pigs ear of it and then having to fork out again for a pro repair.... Driver is an Electro Voice EVM10M (10" / 8 ohm / 200W) Ta!

3below Posted September 14, 2012 Share Posted September 14, 2012 Tried repairing Peavey B/W where the cone edging had lifted from the metal frame - age caused glue to fail. It was not a good result (I am pretty fair at repairs - usually) There is a good amount of info about how to recone available - shims to set voice coil in correct position seems to be the secret. What is blown? describe the damage - cone damage to paper can be fixed with varying degrees of success. Quote Link to comment Share on other sites More sharing options...

[/quote] Couple of times in the past I have found open circuit speakers to be a bad connection where the flexible braid is soldered to the coil, just had to melt the plastic sealant with a soldering iron and re do it. It causes a weird distortion as it makes and breaks when the cone moves. always worth a try, much cheaper than a re cone and if the cone or coil is duff you got nothing to lose.

As you say, nothing to lose! Quote Link to comment Share on other sites More sharing options...
dincz Posted September 15, 2012 Share Posted September 15, 2012 (edited) I've reconed a fair few JBL and SWR drivers but it was some years back. The kits came with shims and glue and it was a pretty straightforward job. I used to clean the coil gap with doubled-over gaffa tape to get rid of bits of old burnt coil and lacqer. Only one went horribly wrong - the voice coil rubbed in the gap and I don't really know why. It's possible that the coil former wasn't correctly aligned to the cone or maybe I didn't clean it carefully enough Edited September 15, 2012 by dincz Quote Link to comment Share on other sites More sharing options...
