Try Audioquest Type 4 speaker cable in bulk. Terminate yourself or leave raw cable ends and twist together. $4/ft and sounds very good once it has run in for a while (breakin key for this AQ wire). Kimber in bulk is another good choice. I like both of these bulk cables because you are paying for the wire and dialectric and not fancy packaging or connectors.
