This is a weird issue

#1 Post by djtrumptight »

So i went to do a sound system set up Sunday morning for a bike show and oddly 1 of my T48's wasnt working.I opened it today and took the driver out and this is what i found

Any idea on how i should fix this ? Right now my plan is to use a circular shaped one of these

I had this driver reconed before and im wondering if the tinsel lead they used was cut too short.

How good are your soldering skills?

If there two pieces were tinned properly, you should be able to solder it back together quickly. With a steady hand.

I can try it but i would much rather go with the most reliable way,which would probably be to replace the connector,i definitely dont want it fail for the same reason again.

The lead may have been too short, or the lead might have not been correctly bent, so it was flexed on long excursions and it eventually snapped. I'd re-solder it, then use the driver break-in procedure to see if the tinsel puts pressure on it in long excursions, bending it as required to prevent that from happening.

If only my soldering skills was that good,as well as my soldering iron.It broke right at the end of the hole that the screw goes threw so it would have been like soldering a "U' shaped piece back onto the main piece.I sorta kinda rigged it,crimped it and soldered it.Its a tight hold but i need to bend it a bit more,i applied a 9 volt battery to it and i can see the whole piece move a little bit on excursion,i will adjust it in the morning then check it according to the break in procedure.Its actually a bit longer now and the tinsel lead has more length.Thanks for the help fellas.

A quality soldering iron Weller or better and Youtube will give you much more confidence in your soldering. You just have to sort out the 'bunk' Youtubes from the helpful ones. I got a Weller adjustable wattage soldering station and haven't looked back. I went through a half dozen Radio Shack, different wattage irons and continued to FAIL at soldering. I got an $80 Weller station with different tips for different jobs and have been very successful. I was presented with a tiny surface mount switch on a Sennheiser wireless mic and said to myself, 'I can't do that!!!'. Well I dove in and success! I've done two more now and they are still in service. Keep the tip clean; make a solder, use the sponge, tin the tip.....keep it in good shape.

Spend the money and get a Weller station. Learn to use that sponge, get thin solder - and you'll wonder why you didn't spend the bucks years ago....

Ditto to the above...it's essential to have a nice soldering station...

I'll also add that a good portable soldering iron for the mobile audio tool kit is nice to have. I've got a Weller butane-powered iron which works well...
