Copper foil

I always start at McMaster-Carr www.mcmaster.com for things like that

Excellent, Regalma1.

Both of you thanks for the info. I just added a single tail copper foil to the negative side of my speakers and the improvement was outstanding as if I upgraded my system. The system sounds fast, dynamic and downright transparent. I was so thrilled that I am trying to get more for my home theatre speakers but McMaster does not have the .0075 thick foil. I will try the .003 that you Muralman1 mentioned.

Thanks

For speaker cables, try 5mil x 2", or 7mil x 2" for more LF emphasis.

gentlemen:

how do you terminate such thin foil ?
