Too confusing

I have been looking at all the classifieds for used speaker cables, and just get more and more confused by the minute. Can someone tell me what the heck I'm looking for?

I am going to vertical or horizontal biamp. The final method I use will be determined after testing and results.

The cables I need must have 4 individual conductors or two pairs within each cable, with each conductor having a banana on the amp end, and a spade on the speaker end. I am told that the 2 pairs of conductors within each cable should be different for the low and high frequencies. Is there anything special about this cable? All the adds I see say "single, single biwire, double biwire, triwire, etc, etc" All the biwires I look at including, the double biwire have the four spades on the speaker end but only two on the amp end. This would be a biwire arrangement but not a biamp arrangement. Can someone please just simply explain this to me?
Sfrounds; I don't think you can use an internal bi-wire cable for bi-amping-- unless it has four individual leads on each end that are clearly marked, and even then, it would not be ideal. As you know, in a bi-amp system, each channel of a stereo or dual-mono amp drives either the bass or treble drivers of one speaker, but not both. I think the best, and maybe only way to bi-amp, is with four individual wires per amp/speaker combination-- this would be a true bi-amp/bi-wire set up. I'm going to be doing this myself in about a week using four individual wires per amp/speaker with all spade connectors. If you purchase used wires by a major manufacturer, you should be able to have them terminated as you need by the maker, but it'll cost a few bucks. Good Luck. Craig continue, if your are going to horizontal bi-amp, you will need four individual runs coming off each amp anyway. My advice is not to mess around with internal bi-wire cables, just get individual wires-- which is sonically better anyway. Also, it is best to use the same wires for both top and bottom frequencies-- this avoids weird colorations and electronic mis-matches between wires and the speakers cross-overs. BTW, this wire advice comes from R. Vandersteen and S. McCormack. R. Vandersteen recommends vertical bi-amping, but says nothing about horizontal. I'm going to do the vertical. Again, good luck to both of us. Craig.
