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

Bi-wired configuration: two connectors at the amplifier end, four at the speaker end. The terminations utilize 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 setscrews. Star quad cable configuration reduces the electromagnetic field around the cable for minimized interaction with other system cabling. Assembled in Seattle, Washington, using proprietary connectors and a Sonobond welder. Locking banana plugs and gold-plated copper 9.2mm spades provide a secure connection at all amplifier and speaker connection points
