Many of these, most notably KLH and Realistic, used RCA connectors for both the amplifier outputs and speaker inputs. Back in the day they were supplied with the flimsiest of molded connector speaker cables.
These superbly flexible round cables feature a pair of 17 AWG conductors, each composed of 56 strands of 1mm oxygen free copper wire. They are terminated with sturdy Amphenol RCA connectors which feature a die-cast satin nickel shell, gold plated contacts and red and white flexible rubber grommets for easy channel identification.
