roughlytraded Posted January 31, 2020 Share Posted January 31, 2020 Hello! Hoping someone can help here, I'm installing new crossovers onto my Cornwall II, and I'm almost done. All that's left are the two cables that run but the Input terminal, but I'm not sure where to put them? I removed the screws to the circuitboard, but there's two pieces still braced against it so I can't lift it up. Pictures attached, does anyone know where to put the binder cables? Second question...for two out of the three drivers, i forgot to take pictures of the L-R wires before, so I'm guessing on which post they go on. is it dangerous for the speaker to test it out like this, and will i know immediately if they're backward? Thanks everyone! Quote Link to comment Share on other sites More sharing options...
PrestonTom Posted January 31, 2020 Share Posted January 31, 2020 The best bet is to contact whoever made/sold these and ask them. I would not guess. Part of the problem is that we can't see the markings on the board. Quote Link to comment Share on other sites More sharing options...
roughlytraded Posted January 31, 2020 Author Share Posted January 31, 2020 i talked to bob, here's his reply, check out the two connectors circled below but i don't have a soldering iron, never used one before. any ideas for how to get the soldered-on wire off the circuit board? "The terminal come all the way through the board and are connected by the bare wire on top of the board. You need to unwind the soldered bare wire from the two connections and then the board will slip off of the terminals. Then with the board out of the way, you can connect the wires you show under the nuts that old the terminals on." Quote Link to comment Share on other sites More sharing options...
PrestonTom Posted January 31, 2020 Share Posted January 31, 2020 If those "wires" are just mechanical fasteners then you might be able to snip them off. However, if they are part of the electrical circuit then do not. Either contact Bob again to get his okay, or have a friend with a solder pencil do it for you. It will only take a minute or two.

roughlytraded Posted January 31, 2020 Author Share Posted January 31, 2020 ok i was able to get them off, wired everything up but now no sound is coming out of the midrange driver. i thought the problem might be that i switched the polarity on the back of the driver, but i tried that and still no sound?

PrestonTom Posted January 31, 2020 Share Posted January 31, 2020 Let me be honest with you. Don't do anything! 1. You took it apart with out taking a picture ahead of time - bad idea 2. You were advised to get "Bob's ok" before going further - apparently you did not - another bad idea 3. I did a google search and within less than a minute I found a schematic and photos of the crossover and wires. Why weren't you able to do this yourself? 4. If the driver is not working after you fooled around with the circuit boards, and connectors, then it is quite likely you have a simple case where you need to check the connections and connectors. This may require require re-flowing a solder joint. This may not be a task for you. I am just being brutally honest. Take everyones advice and call Klipsch 4 Quote Link to comment Share on other sites More sharing options...
Deang Posted February 3, 2020 Share Posted February 3, 2020 He got new networks, he's only reusing the terminal cup and attached binding posts. Your midriver is not working because you probably connected both wires on the same side of the driver. Each side has two connection points. You will have to connect one of the wires to one of the terminals on the other side. But which one? Look at the back of the driver for the "factory mark". The mark is usually done with a magic marker or paint. This is the positive side. Attach the red wire to this side. Dean Quote Link to comment Share on other sites More sharing options...

Deang Posted February 4, 2020 Share Posted February 4, 2020 Maybe not. It was just a guess. Quote Link to comment Share on other sites More sharing options...
ricktate Posted February 4, 2020 Share Posted February 4, 2020 Probably;y have to send to Bob Crites so he can fix it right. next time take pics. 1 Quote Link to comment Share on other sites More sharing options...
