View Full Version : Reason for reconing

Hello and best wishes for 2005 !.

I have to recone one of my Le15A ( I have 2 ) and I can't find any reason why this speaker does not work .
The Le15 began to resound badly more and more , I know he is well protected so it was not hurt and I did not use it so loud !!!, last reconing was 10 years ago .

What can be the reason ?

thank for answers .

Maybe the tinsel leads to the coils are opening up??? Hows the foam???

May be the cone and coil is offset, so the coil is "hanging" in the gap and produces sounds, if you know what i mean ! ten years is a long time and may be surround and spider loosen his strength (?). Sorry about my very bad english.
Turn around the speakers every year 180 degrees, so the top is now at the bottom(?).

After removal from the cabinets, gently move the cone in and out with your fingers on both sides of the edge of the cone. Listen and feel for any rubbing or scraping effect. If not, move around the circumference and repeat. If not still, try gently pushing on just one edge to see if it rubs anywhere around the whole diameter, if not you have no problem with "centering" and your problem may be a possible loose voice coil? Those can sometimes become unglued and separate from the former and rattle loosly around in the gap...or something else causing noise. Have those units been recently re-surrounded? I had some LE15's from the early seventy's or maybe the sixty's and they had the Lans-a-loy type early white/yellow "foam" and they will be hard and brittle by now. I know you said the edges were fine, but I want to be sure. Have a great 2005! RE
