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

Bi-wired setup: 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, without any intervening metal, compression sleeves, or set screws. Star quad cable design decreases the electromagnetic field around the cable for reduced interaction with other system cabling. 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, plated in gold for corrosion-free contact
