If you are using the Dayton Audio double binding post plates, these jumpers
are a must! They allow your speakers to be easily changed between bi-wire,
bi-amp, or single input configurations. The innovative single-piece design
transmits the positive and negative inputs through what appears to be one
central conductor, simplifying installation while providing a unique high-end
look. Designed to work with either the premium or fully insulated binding posts
and the Dayton double binding post plates. Sold individually, one jumper
required per speaker. Two inch center-to-center horizontal fork spacing.
