Canare 4S11 Speaker Cable, with Ultrasonically-Welded Bi-Wire Terminations (One Cable - for one Speaker); Assembled in The USA (12 Foot, Grey, Two Spades to Four Spades)

Bi-wired configuration: two connectors on the amplifier side, four on the speaker side. The terminations use a unique ultrasonic welding process that bonds the copper wire directly to the brass banana or spade connector, without any intervening metal, compression sleeves, or set screws. Star quad cable configuration minimizes the electromagnetic field around the cable, reducing interaction with other system wiring. Assembled in Seattle, Washington using proprietary connectors and a Sonobond welder. The welded spade connectors (9.2mm opening, fitting almost all binding posts) are crafted from solid sheet copper, gold-plated for corrosion-free contact
