Copper foil

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 ?

The ends can be folded down to a pointed triangle and shaped with needle-nose pliers for crimping & soldering inside a convention spade. Alternatively the ends can be folded into several thicknesses and punched for direct copper termination. A Cardas no-stress binding post is perfect for this, as it clamps down without twisting.

Mrtennis, I use silver rhodium spades sourced from Home Grown. To start the narrowing of the ends, I gently curve the edges into a U. I snip the last three centimeters into strips for intertwining. The spades have two allen bolts that secure the intwined copper.

My amps have to be carefully guarded against shorts. That is why I use clean spades. Bare ending the copper to the speaker terminals may be advantageous.
