Canare 4S11 Speaker Cable, with Ultrasonically-Welded Bi-Wire Terminations (One Cable - for one Speaker); Assembled in The USA (50 Foot, Grey, Two Spades to Four Spades)

Bi-wired setup: two connectors at the amplifier end, four at the speaker end. Industry-leading terminations: a special ultrasonic welding method bonds the copper wire directly to the brass banana or spade connector, eliminating extra metal, compression sleeves, or setscrews. Star quad cable design minimizes the electromagnetic field around the cable for less interference with other system wiring. Manufactured in Seattle, Washington at a specialized cable facility, employing 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
