The BC-2S18 (500') by Kramer is an 18-gauge standard bulk speaker cable used for connecting speakers and amplifiers in security, commercial or residential AV systems. It features a twisted pair of unshielded bare-copper conductors designed to inhibit electromagnetic interference and prevent radiation of signal, and is well-suited for relatively short runs (less than 50').
This UL-certified cable offers a temperature rating of 167°F, and a maximum operating voltage of 300V, and it's protected from the rigors of installation by a rugged gray PVC jacket.
