Cardas Cold Forging

Geez Bobby, sorry but I totally missed tuboglo's post. I am on board with the process since I use high pressure hydraulic crimpers on the cables I make; using a similar die, two crimps and trim the spades, very similar to the Cardas video, but of course not the same pressure or degree of fusion. I much prefer that crimped connection to soldered connections I have done, but I haven't tried it on litz wire. I am glad to hear those who have had cold forging done to their Cardas cables prefer the sound, although I would expect nothing less from Cardas.

This process of doing this this does not leave you with a solid one piece of copper. Cutting it open will actually let them separate into multiple pieces again. If they melted and turned into one, that's what you would have, but this most likely wouldn't be the case. Also, this process is actually over crimping. Copper is soft and malleable. If you run the cable at its full rated capacity, you will most likely have a hotter terminal with this method, than a normal proper crimp, with the correct dies used for both crimps. When over crimped like this, some of the copper will squeeze out, leaving a lighter gauge wire, than you started with. I'd like to see the terminal cut the opposite direction, to show this claimed solid theory. Also under a scope before filing, and letting some stray fillings appear to fill the gaps. You could polish the cut end enough to make a nice shiny finish. It is still not one, like taking in to its melting point, and actually turning the multiple pieces into one. For low current speaker termination, I'm guessing this process is fine. I don't think it would ever be adopted for termination that involves carrying electricity to anything, that may have human lives on the line.

we are talking about speaker wire termination and not conducting electricity. but george assures me this connection would be fine for that too.
best, bobby

They can be cut open quite easily, and that would reveal they are not fused. I didn't know anyone used a chisel to check something like this.

For speaker termination, they should get by.

As far as they are not for electricity, speakers need that to make music.

I'm glad I didn't make the claim.

H, are you usually this argumentative about things you cannot disprove? your knowledge of crimping may be considerable but this is not the same process. mr cardas has worked for years to make this a considerable improvement of the norm.
and we are discussing speaker wire terminations here and nothing else. for those that have had this done, they like it and that is all that matters. as i said, first hand knowledge is everything. now is you want to purchase a pair of cold forged speaker cables and chisel them apart which which george said would need to be done, then you would have some first hand knowledge.
have a nice day.
ok?
best, b
