ZEUS121996 Posted November 15, 2017 Share Posted November 15, 2017 The 2007 Khorns I just picked up have a problem with the K-55X drivers. I have no idea how they did it, but they managed to cleanly break off the posts on the drivers themselves. Klipsch tells me I need to buy new diaphragm kits for $105 each. I should be able to solder posts back on or does someone have better idea? Both drivers look like the attached pic. TY Mark Quote Link to comment Share on other sites More sharing options...
jjptkd Posted November 15, 2017 Share Posted November 15, 2017 I don't think it would hurt to try and solder them back together seeing how they're already broken, worth a shot. 1 Quote Link to comment Share on other sites More sharing options...

The corollary would be, how do you solder the terminals safely? Do you take them apart, what temp do you set the soldering iron to so you don't damage the diaphragms? If I thought I could get away with it I'd solder the wires directly to the old terminal stubs. Quote Link to comment Share on other sites More sharing options...

I agree, and Mr. Crites might have some good advice as well..... @BEC 1 Quote Link to comment Share on other sites More sharing options...
ZEUS121996 Posted November 15, 2017 Author Share Posted November 15, 2017 He didn't have the terminals, not a big deal I'm sure. I can't figure out how they did it without damaging anything else. I could solder the wires directly to the drivers, not ideal but functional. Being anal, that would drive me crazy tho Mark Quote Link to comment Share on other sites More sharing options...
ZEUS121996 Posted November 16, 2017 Author Share Posted November 16, 2017 Mr. Crites was nice enough to get back to me immediately. He recommended soldering the wire directly to the drivers. The good thing was the Atlas driver has a small hole I was able to tuck the wire into. It's not pretty with my shakes but I think it will work. Going to fire them up at the club tomorrow and see what happens. I'll also be interested to see how much difference I can hear between the 2007s and the 73s that had been recapped.

The worst case would be new diaphragm kits. Use a small iron, 15 watts?, tin the leads, wet the tip with solder and make the connection as quick as you can. 1 Quote Link to comment Share on other sites More sharing options...
JJkizak Posted November 16, 2017 Share Posted November 16, 2017 Kind of wondering why they went to soldering terminals when the old style worked so well, especially as hard as it is to screw those drivers on the horns with wires flopping around.

I would use a 50 W iron with an 800 deg. tip, pre-tin the wires and the terminal, and sweat them together 1 Quote Link to comment Share on other sites More sharing options...
WMcD Posted November 16, 2017 Share Posted November 16, 2017 Have you tested the resistance at what is left of the connections? My thought is that the lack of terminals might be obscuring a burned out voice coil. In any event, if there is some problem after you're done soldering, it will be instructive to know there wasn't one before you worked on it. (Even if it might cause some self blame. Smile.) (Edit: In retrospect the question may be insulting -- but I'm suspicious of unexplained damage which interferes with casual testing.) A few years ago I bought a temperature controlled Weller soldering station. It really takes the worry out of soldering. If you have the cash you might consider buying one. BTW: Is the unit really from Klipsch, with a Klipsch trademark on the back? You say it came out of a K-Horn. But I see the Atlas tag. You're calling it a K-55-X but is that true in a strict sense?

Marvel Posted November 19, 2017 Share Posted November 19, 2017 Here is a pic of a new Atlas PD-5V. It looks like the terminals could pull off rather easily. There are no posts... Quote Link to comment Share on other sites More sharing options...
