Mediabridge Open-Screw Banana Plugs - 2 Pair Per Package - (Part# SPC-BP1-2 ) Includes 2 pairs of banana plugs, which are meant for attaching to speaker wire and supplying a high-quality signal path from audio components like a speaker to an audio/video receiver, amplifier or other professional sound application. Compatible with bare wire, spades, or other banana plugs, and work with 12-18 AWG speaker wire. Corrosion-resistant gold-plated connectors provide secure fits with clarity, natural sonic accuracy and minimal signal distortion. A 2-piece screw-on design makes for reliable termination. Simply connect existing speaker wires to a plug, either through the bottom or through the holes in the side (step-by-step installation guide included). The plugs are color coded, distinguishing left from right to enable matching polarity. Open-screw is a great plug-and-play alternative to using bare wire when connecting devices, taking away the hassle of fiddling around with fraying speaker wire. Each versatile plug can act as a splitter, with a female banana plug connector on the bottom, allowing you to hook up multiple speakers to a single output (amplifier must be capable of handling increased loads).
