Canare 4S11 Speaker Cable, with Ultrasonically-Welded Bi-Wire Terminations (One Cable - for one Speaker); Assembled in The USA (40 Foot, Black, Two.

Bi-wired configuration: two connectors at the amplifier end, four at the speaker end. The finest terminations in the industry: a unique ultrasonic welding process fuses the copper wire directly to the brass banana or spade connector, with no intervening metal, no compression sleeves or set screws. Star quad cable configuration minimizes the EM field around the cable for reduced interaction with other system cabling. Assembled in Seattle, Washington at our own cable shop, using 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
