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

Bi-wired configuration: two connectors at the amplifier end, four at the speaker end. The terminations use a unique ultrasonic welding process that bonds the copper wire directly to the brass banana or spade connector, without intervening metal, compression sleeves, or setscrews. Star quad cable design minimizes the EM field around the cable for less interaction with other system wiring. Assembled in Seattle, Washington, with proprietary connectors and a Sonobond welder. Locking banana plugs and gold-plated copper 9.2mm spades ensure secure engagement at all amplifier and speaker connection points
