Simple copper speaker terminal jumpers? Lost my originals.


Can anybody recommend simple, but good quality, copper jumpers that bridge the bi-wire terminals?  I mean just the little piece of copper with the openings on each end.  I see the Cardas ones, but I don't understand how you can adjust them for the distance between the terminals, as they seem to be a solid piece.  Can they be bent a bit to make them fit?  Any other suggestions? 

The reason I'm asking is that I seem to have misplaced the original jumpers for my speakers and I found a set lying around the house that seem to have been from different speakers and don't really fit completely onto the terminal posts.  Also, they look more like brass than copper.  So, I'd like to try a different jumper.

Also, I currently have the cables connected to the HF terminals, but I saw on some threads here that people were connecting the cables to the LF terminals and jumping to the HF.  Which do you think is better, audio-wise?

You might be surprised at the good sound one can achieve by purchasing copper wire (12 or 14 gauge) solid or stranded at your local HomeDepo or Lowes store and use that with bare wire terminal jumpers or buy some Duelund 16 gauge tinned - copper in cotton oil impregnated wire as jumpers.

Thanks.  Actually I ran these speakers bi-wired for years, but when I bought some new cables that were not bi-wire type, I found that the sound, including bass, was far superior.  The sound is so much better that I regret having bi-wired them for all those years.  Perhaps it's something to do with Legacy's crossover implementation in these speakers.

I'm currently connected to the HF terminals and jumping to the LF terminals.   The reason for that is that I want to get the best highs and mids, and considering that these jumpers are not very confidence inspiring, I want the cables directly connected to the HF terminals. 
Assuming that one's working with a fixed budget, and assuming that there's not a very special crossover that requires bi-wiring, it seems to me that single wire + jumper of same wire makes the most sense.  I'd rather have one pair of $600 cables running to the speakers, rather than two pairs of $300 cables.
