Canare 4S11 Speaker Cable, with Ultrasonically-Welded Bi-Wire Terminations (One Cable - for one Speaker); Assembled in The USA (40 Foot, Black, Two Spades to Four Spades)

Bi-wired configuration: two connectors at the amplifier end, four at the speaker end. The terminations utilize a distinctive ultrasonic welding method that bonds the copper wire directly to the brass banana or spade connector, eliminating any intervening metal, compression sleeves, or setscrews. Star quad cable arrangement minimizes the electromagnetic field around the cable to reduce interaction with other system wiring. Assembled in Seattle, Washington, with proprietary connectors and a Sonobond welder. The welded spade connectors (9.2mm opening, which fits almost all binding posts) are crafted from solid sheet copper, gold-plated for corrosion-free contact
