Has anyone tried the GR research Klipsch rp600 kit parts on the rp160s. Thanks.

Hi
I will move this topic to the GR Research Circle.
-
Crossovers are specific to the speaker model, so there would need to be a specific crossover redesign for the 160 for you to use. I’m not sure if Danny has worked on the 160.

Disclaimer: I don't have first-hand information on this, but I found this thread over on the Klipsch forums:
https://community.klipsch.com/index.php?/topic/163667-how-to-make-the-rp-160m-come-alive/page/4/ (https://community.klipsch.com/index.php?/topic/163667-how-to-make-the-rp-160m-come-alive/page/4/)
Specifically this quote:
My crossover circuit board even says RP160 / RP600 on it. I know the resistor and Capacitor values are identical and the Inductors most likely are the same values also. I watched all the GR Research stuff on Danny's crossover mods, and have pretty much figured out what he did different than has been talked about here. His results seem pretty good.
My understanding of the rp-600 vs rp160 were mostly cosmetic and the same for the rp-500 vs the rp150. I would suspect using the rp-600 upgrade would yield positive results, but Hawkeyejw is right - sending one to Danny would let you know for sure.

That’s interesting, I did a google search and it looked like different drivers with different enclosures. Didn’t realize they may package the same model with different model numbers.

Take a look at this post: https://www.audiocircle.com/index.php?topic=166535.msg1856414#msg1856414
"Now in terms of sound, I have the Klipsch RP-160M (yes I did check the crossover network and checked with Danny if it could be done to the RP-160M and he replied yes, as many others have done so)."

I feel obligated to flag that at that price scale, just.doinf one of the GR kits might be better. The cost of a mini with a premade cabinet is pretty close to what resale on the Klipsch plus the upgrade kit would be. Since the crossover is a lot of the work on a kit if you don't have to touch the cabinet, the effort is similar.
No judgement or anything, I'm just wonder if the existence of the cheaper kit without requiring any effort on the cabinet changes the math for a number of folks.

I did something similar for my Klipsch center channel. Danny did an upgrade of RP504-C. My center channel was the previous iteration of the center channel model in the premier line (RP450-C). In looking at the crossover, it was labeled for both the RP504-c and RP450-C models. Rolled the dice and haven't regretted it much, as it was an improvement.

the rp600m and 160m share the same crossover board but not 100% sure if the values are the same though. I purchased the rp600m speaker kit from dany. I chose to upgrade the resistors to path audio resistors as they are the best audiophile resistors out. you can only get the path audio at partsconnexion.com or www.hificollective.co.uk I also swapped out the sonicap for a higher quality better sounding cap but it is more expensive. Audyn True Copper or Jupiter Copper Foil Paper and Wax caps will give you more detail, staging, imaging and somewhat more of a warmer sound etc over a sonic cap. Both those caps are considered neutral but has some warmth to them as well. They are bigger size than the sonic cap but not that big to where it would be a problem to fit it on a crossover board. Now Miflex and Dueland caps for example are huge so avoid those. you can also add a small bypass cap that you wire in parallel with the tweeter cap to give it some extra detail if you wanted to. small sizes like .01uf, .1uf, .22uf will work for bypass cap sizes. I wouldnt go over .33uf size for a bypass cap though as it will start to mess with the value of the tweeter cap
