krustyoldsarge Posted October 11, 2002 Share Posted October 11, 2002 Howdy, Anyone out there got a schematic for the kg4 crossover? Anyone know the mh values for the inductors? KG4 00 RV, Speaker Serial number is 8854836, 8854837 Love my KG's! Steve (in S. Korea) Quote Link to comment Share on other sites More sharing options...
dougdrake Posted October 11, 2002 Share Posted October 11, 2002 Hey Sarge - Thanks for serving us and your country!! If no one here has them, email Trey Cannon at Klipsch tech support. He's a poster on this board, so you can find one of his posts and send an email or private msg to him. Love my KG4s, too! Doug Quote Link to comment Share on other sites More sharing options...
Klipsch Employees Trey Cannon Posted October 14, 2002 Klipsch Employees Share Posted October 14, 2002 This should help... If you need more info, let me know. KG-4.pdf Quote Link to comment Share on other sites More sharing options...
STL Posted October 14, 2002 Share Posted October 14, 2002 I believe I have the Cap and Inductor values at home. Email me a reminder, and I'll get you the info... Quote Link to comment Share on other sites More sharing options...
krustyoldsarge Posted October 15, 2002 Author Share Posted October 15, 2002 Got it! Thanks Trey! Looks like the values are .5mh and 1mh, caps are 3uf, 8uf and 33uf. Steve Quote Link to comment Share on other sites More sharing options...
Klipsch Employees Trey Cannon Posted October 15, 2002 Klipsch Employees Share Posted October 15, 2002 Remember to use 100Volt caps ( or higher ) Quote Link to comment Share on other sites More sharing options...
STL Posted October 15, 2002 Share Posted October 15, 2002 Trey is the man! I guess I should have just asked him instead of dragging in my parts and using the inductance meter at work. Quote Link to comment Share on other sites More sharing options...

On my pair of KG4s the values came out to be: 1.134mH, 1.134mH, 0.532mH, and 0.530mH. Quote Link to comment Share on other sites More sharing options...
krustyoldsarge Posted October 17, 2002 Author Share Posted October 17, 2002 Thanks for taking the measurements! Actually that's good info for me right now since I am going to try to hit the electronics district in Seoul this weekend to try and snare this (and some other) stuff. Might be able to get something custom wound. Electronics parts are one of the few bargains left here in Koreas. Of course, when you try to buy some of the high end goodies, you pay and a fair bit of the premium stuff is imported from the States! Also appreciate Trey's reminder to watch the capacitor voltage values on the caps. Always do, and I try to double the voltage rating if I can, in order to bulletproof/derate the project when physically possible. Also, on my shopping list are electrolytics (they're cheap here) to recap my Marantz' power supply section. Interesting that cap technology has gotten to the point where you can double the capacitance and voltage rating of a 1970's era cap in the same physical case. Also want to trade some electrolytics out of the signal path. My neighbor's are probably gonna start calling me "Uncle Dielectric" soon.

krustyoldsarge Posted October 19, 2002 Author Share Posted October 19, 2002 Trey and all, Just got done shopping in Seoul. Got most of what I was looking for. Ran into a very helpful guy who rebuilds speaker drivers and seems to like us Americans. He hooked me up with some Solens 22uf + 12uf = 34uf X2 from another shop for the woofer side. Also sold me some nice, big used air inductors and complete networks pulled from some "wrecked"JBLs. Saved a chunk of Won there! I'm on my way (Hopefully not down the Highway to Hell)! Will most likely buy the tweeter caps from the States (next payday)! How does inductor value work on the tweeter side? Can/should the .5mH be doubled? DO two inductors in series = double value vs. two in parallel = half value (my guess, been many years since electric shop in high school)? I'll check on the web. Looks like I'll definitely need a new board for this hefty stuff. Mount on the bottom of the box on wooden risers? Outside the box? What do you guys think? Also picked up enough of some impressive looking German flat silver wire to rewire the guts. Two meters of the stuff wasn't that expensive, and I'm going in there anyway. Here goes another controversial thread! Quote Link to comment Share on other sites More sharing options...
