Canare 4S11 Speaker Cable, with Ultrasonically-Welded Bi-Wire Terminations (One Cable - for one Speaker); Assembled in The USA (15 Foot, Black, Two Spades to Four Spades)

Bi-wired configuration: two connectors at the amplifier end, four at the speaker end. The finest terminations in the industry: a special ultrasonic welding process fuses the copper wire directly to the brass banana or spade connector, without intervening metal, compression sleeves, or setscrews. Star quad cable configuration reduces the electromagnetic field around the cable for minimized interaction with other system cabling. Assembled in Seattle, Washington at our own cable shop, utilizing proprietary connectors and a Sonobond welder. The welded spade connectors (9.2mm opening, which fits almost all binding posts) are made from solid sheet copper, plated in gold for corrosion-free contact
