Here is an informative website discussing speaker wire in general and the oxygen-free-copper type, OCf

In essence, using good quality copper wire is needed, but reducing the oxygen content of copper wire beyond what it usually is doesn't improve anything in audio applications.

Has anyone seen the cat lately?

Thanks David! Yeah, these II's will be good for quite a while now. And the kitty escaped to safety before the "woofer" came home.

Well if you noticed, I'm just using my own DIY "White Lightening" speaker wire from the amp to the speakers. To me, wire is wire. As long as it's big enough, it'll work just fine. I don't get into all of that marketing stuff.

As for the whole "OFC" thing, I just figured it meant that it wouldn't oxidize so easily or quickly.

This sounds right. Oxygen free and wire size is pretty much the only selection criteria I've ever used.

I do have some old apature 10 gauge wire that I was offered at a 90% discount from a buddy that runs a stereo shop because an error was made in manufacturing and it was terribly oxidized. I've had speakers connected with it though and even though it's as green as the statue of liberty, it still seems to function just fine.

Yeah, for the longest time I used some old original 12awg Monster Cable that my oldest brother had from the early 80's. That stuff was totally green from one end to the other. I just used a knife and scraped off the green on either end and used it for a long time. Later on, I got a job and bought brand spankin' new "original" 12awg Monster Cable... Absolutely no difference in sound.

However, I always enjoyed the smell of new speaker cable and how it filled the room of that fresh rubber smell.

Default update info

Hi Charles
very nice job! I have the same speakers from the 80' and I want to make the same update (I need to refoam them for the 2nd time), could you please tell me if you have done further adjustments or improvements? where is possible to buy online the crossover/plate parts?
any other suggestions?
thanks
best regards
Dario
