Custom jumpers?

IMO: Dekay, Hrcapers, Khaki8, and Leafs each gave correct information. I have tried them and you should too. Select the method that sounds best on your system :-) !

I would give DIY jumpers a try. If you can use the same speaker wire as your long runs try that first.

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!

I have always thought jumper down is the correct method, I cannot see where the reverse would be better.

For optimum results, get a second set of speaker cables. I used to use two sets in years past and it easily outperformed the jumpers I tried. The jumpers were just some heavy gauge speaker wire, I forget what gauge. (I used Cardas Quadlink for highs and Audio Quest Midnight for lows)

I am currently using jumpers though. They are JPS SC2 jumpers. Another company to consider for jumpers is WBT. www.wbtusa.com

Contact Bobby at Merlin. He will make you a set of jumpers using Cardas (?) wire.
