The Gold Eclipse 10 biwire jumper cables provide superior fidelity adapting standard 2-terminal speaker cables to speakers with 4-terminal biwired inputs. Grain Optimized solid silver conductors provide the best sound when the arrows point in the direction the signal flows. For the best preservation of delicate musical information, we recommend connecting speaker cables directly to the high frequency terminals and using the jumpers to connect the low frequency terminals. The jumper arrows should also point to the low frequency terminals. Pack of 4 biwire jumpers with Banana plug or Spade lug terminations. Jumpers are six inches (6") in length.
