Ryan0348 Posted February 25, 2019 Share Posted February 25, 2019 What is purpose of resistors In a crossover. Specifically I have kp301 version 1 speakers and I got some k61 horns and drivers coming so I can convert them to version 2. The version 1 have a 10 ohm resistor in the mid range circuit and a 200 ohm in the tweeter circuit. The version 2 crossovers does not have any in the mid and just a 3.3 ohm in the tweeter circuit. The only difference between the two is a tractrix horn in the mid. And 800hz woofer/mid crossover and 6000 Mid/tweeter. So what does the resistors do for the circut Quote Link to comment Share on other sites More sharing options...
glens Posted February 25, 2019 Share Posted February 25, 2019 Resistors are usually used in a crossover for level matching between drivers and/or impedance shaping. I'm not familiar with those speakers, in either version, so can't offer advice that would be worth a hoot. However, I'd have to guess out loud that you'll want to also go with a "version 2" crossover, assuming the woofers aren't also different between the versions.

jjptkd Posted February 25, 2019 Share Posted February 25, 2019 The series II (301 II) uses a completely different mid driver from all of the home versions, it is a screw on type 2 inch titanium driver used exclusively in the proline Quote Link to comment Share on other sites More sharing options...
Ryan0348 Posted February 25, 2019 Author Share Posted February 25, 2019 Everything is the same. Driver wise. I was gonna build the version 2 crossover so it will all match. Quote Link to comment Share on other sites More sharing options...
jjptkd Posted February 25, 2019 Share Posted February 25, 2019 If you're going to use these for home use I'd recommend building chorus 2 crossovers they are designed for all the drivers you have with a lower crossover point for the mid to woofer section Quote Link to comment Share on other sites More sharing options...

oldtimer Posted February 25, 2019 Share Posted February 25, 2019 But great idea. Let's put someone in charge with a fourth grade vocabulary. Sorry Chad, you are out in the new paradigm. Quote Link to comment Share on other sites More sharing options...
Deang Posted February 25, 2019 Share Posted February 25, 2019 They irritate Bob. Other than that, I don’t think they serve a purpose. Quote Link to comment Share on other sites More sharing options...

Ryan0348 Posted March 2, 2019 Author Share Posted March 2, 2019 So if I’m going active bi amp my kp301s and I’m only going to use the low pass of the mid and high pass of the tweeter there no danger to get rid of the 200 ohm resistors. Since i posted this I have purchased a Xilica crossover with the help of Chris A and I am going active bi amp. Special thanks to Chris for all the help and questions he’s answered. He did tell me I could get rid of everything but the mid low pass and tweeter high pass. I’m not second guessing him at all. I just letting you guys know what happened to this post. I do wonder why the kp301 have a 200 ohm resistor and the chorus 1’s and 2’s have no resistors. Is it cause of the kp301 being more of a pro speaker and they are rated for a lot more dB output so the tweeter won’t blow. I’m a welder by trade so maybe I should have my wife proof read these for me more often. Lol JK Quote Link to comment Share on other sites More sharing options...
Ryan0348 Posted March 2, 2019 Author Share Posted March 2, 2019 I think I might just build the top end of the chorus 2 band pass filter. the low pass of the mid and high pass of the tweeter. It crosses a lil lower then my kp301 and then like Chris said we can do the rest with rew and the Xilica. 1 Quote Link to comment Share on other sites More sharing options...
