Does speaker cable length really matter?

Hi Carl, Sam, Thanks for your thoughts, they helped ease some tension I need to keep my rack on one side of my system for now, forcing me to use longer cables than I would normally use. I hadn't thought of longer interconnects with amp in center, hmmm... Going from an expensive 1 meter to a 3 meter interconnect seems a little impractical financially, and might that not create as many problems as it solves?

Thanks guys,I have installed the 12' cables and they are breaking in as I write. So far they don't seem to have any negative affects. sam, i'll think about your advice in future applications. Appreciate all the help here. Bye for now.
