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

Bi-wired configuration: two connectors at the amplifier end, four at the speaker end. High-quality terminations: a unique ultrasonic welding process fuses the copper wire directly to the brass banana or spade connector, with no intervening metal, compression sleeves, or set screws. Star quad cable configuration reduces the electromagnetic field around the cable for minimized interaction with other system cabling. Assembled in Seattle, Washington using proprietary connectors and specialized welding equipment. The welded spade connectors feature a 9.2mm opening, which fits almost all binding posts, and are made from solid sheet copper, plated in gold for corrosion-free contact
