Tributaries - 6SJ - Series 6 Jumper Cables (Pair) If your speakers are equipped with 4 binding posts they are meant for bi-wiring. One pair is for high frequency and the other pair is for low frequency. If you prefer not to bi-wire, speaker manufacturers provide gold plated brass bars to bridge the negative posts and the positive posts. Using Series 6 Speaker jumpers will improve the performance of your speakers over standard brass binding post bars. The 6SJ is designed with heavy 14AWG High Conductivity Oxygen-Free (HC-OFC) copper conductors that are terminated with a combination of Series 6 spring clip banana plugs and/or Series 6 Spade Lugs. The conductors have a unique individually insulated dual-gauge configuration for superior sound clarity. The 6SJ is terminated with red & black Series 6 spring clip banana plug and/or spade lug connectors. The wires are secured by dual screw terminals.
