Cables that are built to last
From tiniest tweeters to most gigantic subwoofers all speakers need speaker cables. Cables that withstand moisture, heat, cold and vibration. Cables than can handle twisting back and forth for thousands of times if you route them from chassis to doors. Cables that are built to last and are able to deliver the power.
Oxygen free copper
Amongst all materials, only one is second to none when talking about serious signal delivery. That is OXYGEN FREE COPPER aka OFC. It has much better current flow that other materials used for manufacturing cables. Therefore it is an obvious choice for manufacturing FOUR Connect STAGE 2 speaker cables. The cables that deliver. Seriously.
Attention to detail. No single feature makes your cable flexible. Threads are super thin, because thin flexes better than thick, and thin threads improve the current flow. Twisted bundles make cable more flexible than straight, and kill interferences. Silicon based high quality rubber insulation flexes better than crappy plastics, and protects your cable better. This is how SUPER FLEX STAGE 2 is created.
