biwiring using 4PR?

I personally would not run the the cable this way. (3 wires to woofer/1 tweeter). I really think you should consider buying some Kimber 8VS. The VS is much better cable than the PR series. I really don't think running another set of inexpensive cables to your tweeter will do the trick nor will look all that good. Are you using the straping bars on the binding posts that came w/ the spks? If so, remove and use a short length of your PR to go to the tweeter's binding post. This will make things sound better.

This is the way I would do it using your 4PR. Assuming you have enough wire, cut aprx. 6" from each end of your existing cable which are attached to your spks. binding post. Make an 8 wire splice and attach this to your woofer's binding post. (I like to use a little silver-bearing solder just at the ends of the wire. I try not to solder too much as i like to have only cooper make contact w/the binding post.) The short 4 wire 6" cable goes to your tweeter. Or you could use some other cable going to your tweeter. I hope this helps. Bill
