Canare 4S11 Speaker Cable, with Ultrasonically-Welded Conventional (Non-Bi-Wire) Terminations, (One Cable - for one Speaker); Assembled in The USA (20 Foot, Black, Spades to Spades)

Conventional star-quad configuration: two connectors at each end, joined to a pair of opposite-side conductors. This cable is also available in bi-wired configurations. Featuring premium terminations: a unique ultrasonic welding process fuses the copper wire directly to the brass banana or spade connector, eliminating intervening metal, compression sleeves, or setscrews. The star quad cable configuration reduces the electromagnetic field around the cable, minimizing interaction with other system cabling. Assembled in Seattle, Washington, using proprietary connectors and a Sonobond welder. The spade lugs, with a 9.2mm opening, are made from gold-plated sheet copper and fit almost all binding posts
