Codyred Posted January 6, 2018 Share Posted January 6, 2018 Hi All, Just want to inform you of a nice tweak for the RF7II's. I have changed the jumpers on my speakers a few times, abandoning the stock brass metal jumpers a few years ago. I have used solid core (JW Audio Cryo Nova), no name aftermarket jumpers, and bare cable (Audioquest sliver plated copper jumpers). But the ones that have really beefed up and opened up the midrange have been Mogami 10 gauge. These jumpers have made the midrange and highs have a presence I have not heard in the previous years I owned the RF7II's. I highly recommend them. By the way, a respected audiophile, Duster, at Audio Asylum posted in the past recommending that for speaker jumpers to get the heaviest gauge possible, as low as 9 gauge. The fact that I am getting improvement in the midrange presence from these 10 gauge jumpers, backs up his recommendation. Your mileage may vary, but worth trying. Quote from Duster at Audio Asylum: "Believe it or not, a jumper really needs a rather massive aggregate gauge in order to provide any body. High conductivity is very important for a bi-wire jumper (bridging from either direction). I tested one 20 AWG solid core conductor at a time and found that at least an 11 AWG aggregate gauge per leg was needed. 9 AWG is not uncommon in commercial products."

Schu Posted January 6, 2018 Share Posted January 6, 2018 Did you do the evaluation with your eyes shut? Because you know, seeing is not believing. Quote Link to comment Share on other sites More sharing options...
Codyred Posted January 6, 2018 Author Share Posted January 6, 2018 Ha! No, I remember reading about that in a post, but I tend to listen with my eyes open and ears! Quote Link to comment Share on other sites More sharing options...
wuzzzer Posted January 7, 2018 Share Posted January 7, 2018 What happens when the audio signal goes through the thin gauge wire inside the speaker? Quote Link to comment Share on other sites More sharing options...

I had the same thoughts. However, I can see how there might be some benefit to improving the jumper, just as there is with using the right gauge speaker wire for the distance. I don't know whats inside my RF-7II, but my Forte II now have pretty decent gauge wire thanks to Crites x-over replacement. It's also a very short run internally. The jumpers from Klipsch are going to be the most economical solution, and maybe not the best conductor. Why not swap them? Honestly I hate that they are even there, bi-amping and bi-wiring is rarely done, and when it's done it's rarely done properly (if bi-wiring can even be done properly). Hmm. Maybe a better upgrade is to replace the bi-wireable RF-7II terminals with single, eliminate the stupid middle man. Quote Link to comment Share on other sites More sharing options...
Codyred Posted January 10, 2018 Author Share Posted January 10, 2018 I had another pair of jumpers that I had yet to try. These are Canare 4S11 (11 gauge). Replacing the Mogami jumpers with the Canare brought on more clarity and refinement to the presentation of the RF7II's. That is an improvement to my ears.
