Canare 4S11 Speaker Cable, with Ultrasonically-Welded Conventional (Non-Bi-Wire) Terminations, (One Cable - for one Speaker); Assembled in The USA (30 Foot, Black, Spades to Spades)

Conventional star-quad configuration: two connectors at each end, connected to a pair of opposite-side conductors. This cable is also offered in bi-wired arrangements. The terminations utilize a distinctive ultrasonic welding method that bonds the copper wire directly to the brass banana or spade connector, without any intervening metal, compression sleeves, or setscrews. Star quad cable configuration minimizes the EM field around the cable for less interaction with other system cabling. Assembled in Seattle, Washington, employing proprietary connectors and a Sonobond welder. The spade lugs, featuring a 9.2mm opening, are crafted from gold-plated sheet copper and fit almost all binding posts
