I am Not hurting anything right ??

Paulwp - The point, I believe, is that current is the same throughout a series circuit. The + speaker wire, the crossover and driver, and the - speaker wire comprise a series circuit. The amount of current for a given voltage applied depends on the impedance of the load - the crossover/driver, but it is the same in the entire circuit. That is; there is not a lot of current down the + wire to the post, then a little current through the load, then a lot of current back through through the - wire. (Discussion of electromagnetic field needed here, but beyond scope) The crossover is frequency sensitive and represents a high impedance to frequencies outside its bandpass. Current resulting from voltage alternating at frequencies outside its bandpass is therefore relatively small and it is so through the entire series circuit including the wires. No harm is being done by biwiring with the jumpers in place, however. It is the same as running two wires to each post of non-biwirable speakers - each "polarity" wire of the set is simply common at both ends - you are just running more wire in parallel to each post. Do your speaker wires have multiple strands? Same thing. Some may feel that it is advisable to do or not do one or the other because of different sound, but that is a different discussion. :)

Thanks Sndsel, that makes it a little clearer, I think. I do prefer my own speakers bi-wired and think people should just try it both ways and see if it makes any difference to them.

Thanks to all.

My general non scietific "sense" told me that running the jumpers + my Biwire cable (kimber 8 pr) would be the same as running "standard cable" on two posts. As always though I have this FEAR of hooking something up wrong and smelling smoke! (What I like to call the bad smell) As always I appreciate the knowledge and advise I get from this site!

Best Regards

I recall reading in another thread about the practice of using a jumber on the (-) side only in a bi-wire setup. Does anyone do this? I did not understand the explanation that was given before (and probably won't this time either if it comes up).

It was a recommended tweak to try, by Jon Risch at AA, which I mentioned previously. Doesnt work for me. My speakers sound better to me with no jumpers. But some people report that they like it. I dont know why.
