CMG Posted June 27, 2019 Share Posted June 27, 2019 I recently acquired a set of used KLF 20 speakers. While putting then into the car I hear a loud sound and realize the crossovers were in the bottom on the speaker not attached to anything. Upon further investigation, the crossovers are not stock since I have another set of 20's at home. I am not an electrical engineer, so I'm not sure if they are just a DIY job or from a reputable crossover builder. I would like to know if it is a DIY job, if they choose "good components" or if there is something I could change to make them better. I have only a limited time listening to the new speakers but they didn't sound bad when they were on. I removed the tweeters but the divers look to be stock other than the crossovers.

babadono Posted June 27, 2019 Share Posted June 27, 2019 First I'm no expert, but it looks like DIY but with pretty darn good components. What say you @Deang? or @BEC? Quote Link to comment Share on other sites More sharing options...
Deang Posted June 27, 2019 Share Posted June 27, 2019 Parts I use (but I didn't build them). AudioCap PPT Theta film and foils in the high pass Erse Super Q low pass coil Jantzen CrossCap low pass capacitor Mills resistors Supra tin annealed stranded copper wire Provided the values are correct -- should sound awesome.

CMG Posted June 27, 2019 Author Share Posted June 27, 2019 Would the individual have just known what to use and then built it? Gotten the wiring schematic and done it themselves or is there a kit? The guy was from Central Ohio, not sure if he happened to know someone. Glad to hear they are good components, I'll have to hook them up again and see what they can do. Thanks.

babadono Posted June 27, 2019 Share Posted June 27, 2019 there's a thread with Klipsch crossover schematics. I don't know if KLF-20 is in there. Quote Link to comment Share on other sites More sharing options...
babadono Posted June 27, 2019 Share Posted June 27, 2019 And its there on page one. Kind of hard for this old man to make out some of the values when i blow it up enough to read. But should be easy for you to check and see if it is built correctly or been modified. Quote Link to comment Share on other sites More sharing options...
Deang Posted June 27, 2019 Share Posted June 27, 2019 It looks correct. He used the schematic and bought the parts - no kit. Quote Link to comment Share on other sites More sharing options...
CMG Posted June 27, 2019 Author Share Posted June 27, 2019 I appreciate the help in identification of the parts and what I purchased. Sometimes buying from Craigslist will get interesting results. I posted this question on another forum and was told they were junk and to update to something else. Looks like I'll be switching them with the stock ones to try and A/B them.

Deang Posted June 27, 2019 Share Posted June 27, 2019 "Junk", lol. How much did you pay for the speakers? $350.00 worth of parts on those boards, and if I were to build them for someone, the cost would be $600.00. So, enjoy. Quote Link to comment Share on other sites More sharing options...
CMG Posted June 27, 2019 Author Share Posted June 27, 2019 I paid a little more, but I also got a C7 center, rs7 sides, sw 12, and the towers. Not all forums are as friendly or as helpful as this one. That's why I came over here to ask, just took a minute to reset my password. 1 Quote Link to comment Share on other sites More sharing options...
CMG Posted June 27, 2019 Author Share Posted June 27, 2019 I'm not knocking the build, just not something I know a lot about. I think the guy who built them did a good job. And all. I also think there are many people who like to troll the internet when someone asks an innocent question. 1 Quote Link to comment Share on other sites More sharing options...
Deang Posted June 27, 2019 Share Posted June 27, 2019 I didn't think you were knocking the build. It's good that you came over here. Welcome back. Quote Link to comment Share on other sites More sharing options...
Heritage_Head Posted June 27, 2019 Share Posted June 27, 2019 That nice you would think they would have at least used velcro to hold them in place.... Congrats by the way. Quote Link to comment Share on other sites More sharing options...
