not my precious heresy!!!!!

Oh NO!!!!

Today I was thumping away with my Heresy's and my KSW15 and I thought it sounded a little bright. After turning it down I discovered the the woofer in the Heresy II was not functioning. I about lost it. Many four letter words were involved.

After I settled down I took out the woofer and realized what had happened. The positive feed (after the speaker wire hookup on the basket) broke off from the woofer. I hope you understand what I mean. The thin silver wire from basket to paper woofer broke reight at the point where it goes throught the woofer.

Now I have just enough (barely) to sodder the two back together, but the first times I tried it broke again. This is because of the movement, the sodder is not flexible.

Do you think that I could sodder and then put super glue or other type of glue on the sodder to hold it and prevent it from breaking? But I don't want to damage the paper woofer or discolor. I am thinking maybe about that black stuff they use under the dust caps of woofers. I have no idea where to get such an item nor do I know what it is called.

Please please help. Anyones input or help would be GREATLY appreciated!!!!! Thank You!!!

Yes I know what you mean...

I did have some old speakers years ago and the same thing did happen.

Just use a weak(15-20W)soldering iron,DO NOT USE POWERFUL IRONS(25-45W)you may ruin the driver.

Just solder the tip of the wire,then use a flexible glue(go to a good hardware store and ask the specialist there for a flexible glue).

Dont use SUPERGLUE,these are good for hard surfaces that dont move,vibrate.A woofer vbrates,so a flexible glue must be used.

Even bry the glue should have some flexibility.And dont put too much glue on the spot,cover the spot around it too.Most of these glues come in glass bottles with a small brush like alpicator.

Again ask the hardware store and explain on what the glue goes on and it has ro remain flexible.Dont buy SUPERGLUE.

I did repair two woofers my way and they worked very well after(may still work,I gave these away).

Good luck,

OUPS!

Not good,even in a lower shape then the woofers I fixed.

Do you at least see the wires(sticking just a bit out?)

If yes all is not lost...

first I would use the glue just below the break(closer to the outer edge) to hold the two covered leads(wires).If you can then use a 15-20W soldering iron to just join the leads(wires).If you can do this try the woofer at very low input to see(hear) if it works.

If it does gently apply more glue around and on the problem area.Now try again...witha weak signal..does it work...

If yes wait 10-15 minutes and apply a thin coat on the opposite side.BOTH SIDES MUST BE REINFORCED

The cone is very dry,if not this would not happen.

It may happen to your second woofer too! I would reinforce the second the same way(care is of importance here too,it could break).

Only very old and dry paper cone suffer from this.

Check the sourround!It may also be very dry and ready to fall apart.

Speakers dont like to sit in very dry rooms.After 10-20 years in a very dry room or too close to heating elements sourrounds,paper cones and glues start to fall apart.

I almost lost by Sunfire Mark II this way,it was too close to a electric heater.The thick sourround started to dry up ! Frown.gif I was lucky it found this out and applied a good dose of Mink Oil(used on leather shoes)this way the sourroundsa retain flexibility and will not crack.

Heat sources should be away,dont expose speaker to direct sunlight.

Hope this helps a bit more,

Most of the time the K43 may be repaired without re-coning.Usually the tinsel lead goes open where it is crimped to the voice coil wire just under the dustcap.Cut the dustcap off with an exacto knife leaving a 1/8" ridge to glue the new dustcap over.Replace both tinsel leads while you are at it.Use GOOP to glue the connection back on to the cone, RC56 for the dustcap to cone.Wait a day for the glues to cure.Cost you about $2.

Thanks TheEAR and djk! I will try this and I hope all goes well. I have heard of GOOP. I used it for a couple of jobs around the house. Is there any particular one you suggest? I suppose one that is somewhat flexible, but if there is a particular type of GOOP to use let me know.

Once again thanks!
