Whirlwind Power Series multipair cable is a cable within a cable - the outer layer contains audio pairs surrounding an inner core of 2 pairs of 14 ga. wire that has its own overall foil shield and jacket. Each of the two speaker lines is terminated with 2 paralleled 1/4" jacks on the box. A heavy-duty wire mesh strain relief secures the multipair cable to the box and a wire mesh hanger grip is provided at the fanout.
Whirlwind is often asked about the advisability of running speaker level signals in the same cable as mic level signals - the concern being possible crosstalk from the speaker lines into the mic lines.
Whirlwind pioneered the Medusa Power Series snake and has been producing it for over 30 years. In all that time, they have never encountered an issue with crosstalk caused by the snake. The Medusa Power snake was designed so that the geometry of the cable creates physical distance between the separate sections, guarding against crosstalk.
There are other issues regarding power loss and damping factor that can come into play when running speaker lines long distances but that is the case whether or not the speaker cables are integrated into a single snake or split into separate cables.
