SpeakOn plugs feature the quick-lock locking system and have become recognized as an industry standard. The contacts are designed to prevent damage from arcing if disconnected under load, ensuring fail-safe conditions for both the equipment and operator. The plugs also have a rigid plastic sleeve molded directly over the soldering points for maximum protection. A flexible, ergonomically shaped plug housing is then overmolded on the plug, offering supreme strain relief. Plus, Planet Waves speaker cables use 14 AWG oxygen-free copper wire which delivers enhanced clarity and maximum transfer of power to your speakers.Quick-locking SpeakOn plugs Strain relief at critical points Safe if disconnected under load Rigid plastic sleeve over joints Ergonomically shaped plug housing 14 AWG oxygen-free copper wire Limited lifetime warranty
