It has been my experience that custom wire will always perform better. Another tip would be to play around with your speaker wire connections, that is, jumper down or jumper up. I was told by a speaker manufacturer to try jumper down (connect speaker wire to the mid/high connector with the jumper supplying to the bass driver). With my small Aerial that I had at the time, jumper down was better than jumper up. Try it!
Custom jumpers?
Are the stock gold jumpers for Bi-wirable speakers any good? I was wondering if short runs of high quality speaker wire between the posts would be better? Of course there is the possibility that I'm a complete weenie who thinks about this stuff too much and I should just not worry about this kind of crap!!!
