oldmeo Posted April 15, 2012 Report Share Posted April 15, 2012 Hello all,My first time here. I just bougt a pair of model 5's and after reading about recaps the crossover that will make the speakers sing better I think I'm going to do it and this is my very first time but I have been workingin manufacture PC board building and remorking since 1987 so soldering should not be a problem with me This morning I removed both of Xovers. What I have done so far before ordering parts:I measured all the resistors and they are all fine except the R3 = 1.5, 0.5, 0.5 ohm. It changes when I turn the back switch. It's the same for both Xovers. According the drawing R3 should be 6 ohm so why it shows less? is it right or I have to replaced it?My woofers are different in the back so which one is original woofer? one is square and another one is round.I did deoxit both switches.Thanks,Vu Link to comment Share on other sites More sharing options...
Carlspeak Posted April 15, 2012 Report Share Posted April 15, 2012 I suggest, just to be sure, replace all caps and resistors as I did. Below is a pic of a upgraded board and original one.Mills resistors and Dayton caps will get the job done. I have more photos if needed. Link to comment Share on other sites More sharing options...
day67 Posted April 16, 2012 Report Share Posted April 16, 2012 Both the round and the square magnets were found on the Model 5 Woofers. I don't know where in production this change occured. Same with the crossovers. There are at least 2 different versions I know of. The ones shown look like niether I have seen. Very nice, BTW! Link to comment Share on other sites More sharing options...
JKent Posted April 16, 2012 Report Share Posted April 16, 2012 Hi Vu and welcomeI agree with Carl. If you search here there is at least one long thread on recapping KLH Fives. I did a couple of them, with some help from Carl. "Normally" wire wound resistors don't go bad but KLH used 5 watt resistors and I have seen at least 2 case of failed/burned resistors in a Five and the similar Twelve.The Mills resistors Carl used are very nice but you can also use plain sand cast, less expensive ones. Erseaudio has very good caps and inexpensive resistors. Another source is Parts Connexion--they have Axon caps 50% off.Kent Link to comment Share on other sites More sharing options...
oldmeo Posted April 17, 2012 Author Report Share Posted April 17, 2012 Thank you all for responding.Yes I will replace them.Will post picture when it's done and I can't wait to hear my model 5's sing with new X-over. Link to comment Share on other sites More sharing options...
